Yes Michael, I understand it shears at 1441. I went back and read all the data you published but I was unable to determine whether you tested at any velocities lower than 1441. I want to know if it will reliably shear at 1200, 1000, or even 850? I plan to mount a scope and work up a minimum velocity load, then work up to whatever I can safely shoot without getting magnum eyebrow. If there is enough metal a Leupy 2.5 Scout Scope would be the ticket. With that setup maximum velocity will be my desire. One step at a time.

Drew.... No, I never tested below 1440 and that really was more of a fluke than a determined test for LVSP. Mass is pushing the blades with that big bullet, and I really don't know what LVSP would be? Will be looking forward to your work on this....... As for the EoTech, I had Tanks mounted on my 500 MDM for awhile until his came in. One of my rifles has a forward rail from SSK on it and Tanks has the rail mounted on the receiver.....

I would like to suggest that the terminals testing is not over. consider the following from another thread on Bib Bores:
At the moment, the .375" 235grain ER raptor has a BC of .337 and is stable in normal twist barrels (12"). However, the .416", .458", and .510" bullets do not have high BC bullets that are stable in 16" barrels. The 350 grain tipped raptor in .500" only has a BC of .270. It is probably possible to design something around .400 BC and stable by leaving the 13 degree "solid" formula and maybe by redesigning the nose instead of relying on a large plastic tip needing a hollow point itself. +-+-+-+-+-+-+ "A well-rounded hunting battery might include: 500 AccRel Nyati, 416 Rigby or 416 Ruger, 375Ruger or 338WM, 308 or 270, 243, 223" -- Conserving creation, hunting the harvest. | |||

PS: the benefit of a .400 BC is a bullet that retains wonder working energy at 150, 250, and 300 yards. In addition, the bullet will shoot considerably flatter from 150-300 yards. +-+-+-+-+-+-+ "A well-rounded hunting battery might include: 500 AccRel Nyati, 416 Rigby or 416 Ruger, 375Ruger or 338WM, 308 or 270, 243, 223" -- Conserving creation, hunting the harvest. | |||

Tanz, The brass Solids and Raptors (formerly known as BBW#13 Solid and BBW#13 HP) were designed from the ‘get go’ as very deadly close range DG bullets, never as 400yd high-BC bullets. Dan and the CEB staff have done wonders with the Talon Tips to give the Raptors greater BC including the latest ER (Extended Range) Raptor iterations.
CEB does offer the high BC MTH (MTH = Match Tactical Hunting) bullets in .416 caliber: MTH_V11: Bullet Diameter: .416" Bullet Weight: 350 grains Bullet Length: 1.547" Projection Length: .784" Required Twist Rate: 1:17" or faster G1 Ballistic Coefficient: .550 Their .510 caliber offering is much longer and heavier than you’d want to use for DG hunting purposes: MTH_X04: Bullet Diameter: .510" Bullet Weight: 798 grains Bullet Length: 2.501" Projection Length: 1.809" Required Twist Rate: Standard Twist G1 Ballistic Coefficient: .970 However CEB is certainly willing to modify an existing MTH bullets specification or to create a new MTH bullet in a caliber they don’t offer as a ‘standard shelf’ model. I in fact had Dan design two MTH bullets in .423 and .500 caliber, modified with the Multi-Narrow-Banding (MNB) from their discontinued FBH (Flat Base Hunting) bullets: Here’s a photograph of the FBH_C36 150gr .308 caliber bullet (450BC, .830” Nose Projection) that the banding on my MTH bullets is drawn from: Jim "Life's hard; it's harder if you're stupid" John Wayne | |||

Capo, Yes, those dimensions and designs are exactly the kind of thing necessary for the the long-range side of a bullet design. And by long range, we are including short range figures like 150-300 yards. As Michael noticed long ago on this thread, the energy figures and velocities drop off at a precipitous rate with a large meplat, so much so that he is interested in tips for dangerous game bullets. I am also interested in tips/BC for making a dangerous game bullet an all-around bullet. However, the MTH copper design focuses on in-flight ballistics and leaves out the discussion of terminal ballistics. The MTH will allow the hunter to put the bullet on target, and it will also allow it to be used in California with those blacktail mule deer, but the question that I raise is whether or not the terminal ballistics would be improved by being done in brass rather than copper? The materials question needs to be worked out in hollow point designs without reference to accompanying flatnose solids. The flatnose solid should remain as is, with a low BC (around .150--.200). The solids are primarily a backup bullet at fleeing game or for dangerous game work up close. Weight and bearing surface can be kept reasonably close to the hollow points in order to facilitate same PointOfImpact. However, POI considerations only apply out to about 100-125 yards. After that point the low BC of a non-tipped solid makes approximately similar POI (within 1") a physical impossibility. After the materials question is worked out between copper and brass for ultimate BC and stability, a final question will concern ultimate nose tip design. Currently, the CEB bullets use a hollow point plastic tip in order to maintain stability and accuracy with the large plastic tips. With a redesigned nose in brass, would it be possible to design a small pointed plastic tip, like the Barnes blue-tips? Just what happens to stability with these hollow points and solid tips? I don't have a clue, myself. But I'm pretty sure that a "brass MTH" could be designed that would join the better in-flight characteristics of the MTH design with the better terminal characteristics of the raptor design. +-+-+-+-+-+-+ "A well-rounded hunting battery might include: 500 AccRel Nyati, 416 Rigby or 416 Ruger, 375Ruger or 338WM, 308 or 270, 243, 223" -- Conserving creation, hunting the harvest. | |||

Tanz, You drove me to thumb back through the TBP pages to page 192 for this: I don’t believe there’s an issue with the terminal performance of the CEB MTH bullets. And the primary difference between how the brass and copper petals, or blades, is how far they radiate away from the shank during penetration. The brass petals radiate wider while the copper petals radiate closer to the shank’s wound channel – but the overall trauma enhancement is about the same.

The pictures of the 'pointy things' above, bear a striking resemblance to those made by GSC in South Africa since 1997. Of course these bullets are now made in Michigan USA as well. Impact at 1600 fps. Pardon the quality of some of these photos, some were done on film camera, they do go back a while. | |||

Capo, do you have testing data on the .416 350 gr MTH? AIU | |||

It would depend what you want to do with your 416. If it is plains game that you are after, GSC makes a 330gr bullet with a good BC . This bullet has seen testing on the range at the design stage and then on plains game. It has been in use in Africa since 2002 and works well. For dangerous game, there is of course the GSC FN bullet. | |||

Ok, now to the discussion of a brass construction MTH style bullet with a small synthetic tip… This is actually incorrect. The hollowed tip evolved from Michael’s testing which indicated that in certain situations the original tips (lacking the hollowed tip) would break off at the bullet meplat leaving the tip shank within the bullet’s hollow point causing the bullet to perform identical to a solid. I believe this was first identified with the larger caliber bullets and I don’t recollect whether there was also an issue with the rat caliber tips. Basically what you’re talking about is the new CEB LAZER style tipped bullets – an MTH style high BC bullet with a small synthetic tip. Except that you desire it constructed in brass rather than copper and in .416 caliber. Or perhaps the better answer is that you desire the current 350gr .416 MTH_V11 bullet to be modified to accommodate the LAZER style tip – and have it constructed from brass. At least that’s my perception of what you’re looking for. Would this work? Most likely it would – but – I believe first you’d need to identify the target game to assure that the petals would be of proper thickness and weight to correctly perform within the target game. And as Michael has demonstrated it’d be thinner for thin skinned game and thicker for buffalo and the largest plains game. Stuff to think about… Jim "Life's hard; it's harder if you're stupid" John Wayne | |||

AIU, Michael hasn't tested the .416 caliber MTH bullets so no bullet box results. I'm not sure what the CEB guys may have; phone them or email them and they'll certainly let you know. Gerard, From what I understand from Ron Berry, your 330gr .416 HV bullet will work just fine on buffalo as well as long distance for plains game. A very good matched pair are your GSC HV and FN bullets. I'm sure both will see greater use now that they're readily available from your USA manufacturing site.

I suppose that is part of the question at hand--is the overall copper trauma equal to the overall brass trauma? If it is, then the MTH will be fine, as well as GSC and TTSX. If not, then a brass version remains to be done. The secondary question revolves around optimum BC and stability. I should probably mention here that I had trouble trying to get the 338WM to shoot the tipped raptors. I was not able to find a solution with the short windows of opportunity for me to test in the US and now I no longer have a 338WM for testing in the US. So by default we are staying with the .514 BC of the 225 TTSX. It is not a bad bullet, quite the opposite. And they were tested here on 'terminals' way back towards the beginning. For other calibres related to BC and stability: thanks to the USA production of GSCustom I recently picked up a box of 330 grain .416" GSC HV's, but have not been able to fully test them. I've only shot a few bullets in order to extrapolate the grains-of-powder/velocity for Rel-17 powder. Accuracy will await my next opportunity to do load development, possibly not until 2015. Meanwhile, the BC of the GSC is .368" and the TTSX is .444. Both are acceptable for hunting out to 400 yards and the question for them will become which shoots better in the particular rifle(s). I am reluctant to go down to 225 grain CEB for buffalo as a first choice. I haven't yet tried the 300 grain CEB's and am looking foward to testing them in the 1:16.5" traditional twist of the 416 Rigby. On paper it should work, but CEB suggests 1:14". We'll see on my next stay in Calif. Michael gave me some .416s for testing and I think that some 300grainers are in the mix. +-+-+-+-+-+-+ "A well-rounded hunting battery might include: 500 AccRel Nyati, 416 Rigby or 416 Ruger, 375Ruger or 338WM, 308 or 270, 243, 223" -- Conserving creation, hunting the harvest. | |||

Could you check on that? I'm not sure how you access results on the forum. My memory says that there were also stability/accuracy factors with the long plastic tips and that those were solved when they drilled a little hollow point in the plastic tip. +-+-+-+-+-+-+ "A well-rounded hunting battery might include: 500 AccRel Nyati, 416 Rigby or 416 Ruger, 375Ruger or 338WM, 308 or 270, 243, 223" -- Conserving creation, hunting the harvest. | |||

Tanz...... The story is that when we got to the 9.3 caliber tips and up, the material the tips are made of was too dense and heavy at that caliber +. They would not break up and disintegrate like the smaller caliber tips. When this happened, the shear and TERMINAL stability was effected negatively to say the least. The Hollow Point running down into the stem of these tips solved all those issues. It not only weakened the tip internally, but I believe we also get a hydraulic action in aqueous material and tissue of course.... Since the HPs were done, there have been zero issues with the heavy caliber tips.....

Michael, What was causing the stability/accuracy issues when tips were added? You were giving examples of various weighted tipped bullets having trouble in individual guns.

SLOW TWIST RATES...... Examples that come to mind.... 223... 1:12-1:14 Twists... I can take the standard 55 Raptor shoots great, NO TIP ADDED.... Add the Tip, sideways at 50 yards.... Bullet too long for those twist rates.... I use now standard 50 Raptor with tips, and they are fine in those slower twists, but I had two Win bolt guns rebarreled with 1:8 twists, all 1:9 do excellent with all.... Example... 308 with 1:12 twist...... Shoots great with 100 Raptors with tips, 1 tiny hole.... 130 with no tips great... Add tip to 130, bullet too long for twist, accuracy goes to crap...... Need 1:10 twist at max for 130s and tips.... But I use standard the 100 in all these rifles........ Many of the slower twist guns will do fine with the ESP Raptors and no tips, but add that tip, they are way too long and cannot stabilize. Yes, crazy as it sounds, just the addition of the tip in slow twists makes the difference in length and stability...... In the beginning Dan and I guessed all the weights in the rat guns too heavy, even if they were light for caliber, the addition of the tip was just too much, so going 10-=15 grains lighter (shorter) made all the difference in the world... CEB has some recommendations for various twist rates with these bullets, and they are spot on, so pay attention to those...

Agreed. So with the 500 AR Nyati we have a 1:12" twist. On JBMballistics it often generates stability factors of 7 to 10, which is far above typical expectations (1.5--2.5). However, with the CZ 416 Rigby everything is traditional, including the 1:16.5" twist. The only way around this would be to rebarrel. What is surprising is that the 350grain TTSX works fine in the CZ, despite its 1.603" length and stability factor of 1.579. So why wouldn't a 300grain tipped CEB work? The tipped .416" 300gn CEB is 1.623" long including the .332" tip. The JBM formula lists 2.036 as the stability factor, presumably plenty, but CEB says 14" is minimum twist. +-+-+-+-+-+-+ "A well-rounded hunting battery might include: 500 AccRel Nyati, 416 Rigby or 416 Ruger, 375Ruger or 338WM, 308 or 270, 243, 223" -- Conserving creation, hunting the harvest. | |||

When using the JBM Ballistics stability calculator for monometal bullets, make sure you use the McCoy based program. The Miller based system does not work with monos, only some jacketed lead core bullets. http://www.jbmballistics.com/cgi-bin/jbmdrag-5.1.cgi | |||

I'll vouch for that one. It is a 340-grain/.395-caliber HV from my rifle that was caught by 5-gallon buckets of water at 25 yards, using a reduced load with 40 grains of AA-5744 in the .395 Tatanka (1:12" twist). I used Dacron fluff filler with that load of AA-5744. MV was 1672 fps so it was indeed nigh onto 1600 fps at 25 yards. Gerard got that bullet right on his first try with a custom order of a prototype "experimental" bullet, with hitherto unknown barrel by McGowen, of assumed .395 groove and .388 bore. Historic. The Eagle landed safely. More history from about 2007: That early "Noncon" from S&H of 310-grain/.395-caliber brass hollow point make. It looked about the same whether hitting water at either 1700 fps or 2800 fps, and worked well on game at top end, just as devastating as the later CEB copycat bullets: "Q Sign" Exit wound: Another Noncon "Q Sign": More Noncon "Q Signs": All one-shot kills except for the wart hog I gut shot through the "long grass," sorry to say, he required a second Noncon. However the bigger baboon above got an insurance shot with an FN solid. The Copper GSC HV might be more accurate and has a higher BC, and can also be driven to over 2700 fps in the .395 Tatanka. Drop and windage check at 300 yards could be used to estimate the lower BC of that S&H Brass Noncon, the SHARRC "Velohexploder": | |||

I would second that. It would be nice to see what the witness cards show on the spread of the petals, assuming he shoots them over 2600fps impact.

That 330gr GSC HV bullet has been in use close to 10 years and it works very well indeed. It was not designed for point blank testing however, because that only tells a third of the story. Of course it must get the job done at close range and that it will do. We test at three distances to ensure that the bullet performs well over the entire range so that the window of application is guaranteed to be as wide as possible. | |||

Depending on the caliber it would be 25 to 50, 100 and 200 to 300 for HV and HP. Point blank, 50 and 100 for FN. I test on water only because how the bullet reacts is of importance. After range testing, the bullet is taken afield and not by me, by a variety of testers. SP bullets are usually farmed out for testing. I do not have the equipment for the distances at which these bullets are used and point blank does not feature anyway. | |||

Two or three Homer buckets full of water will stop most bigbore softpoints, nesting lid to base in-line on their sides. I started the tests with 10 buckets in a row, and soon found it did not take anywhere near 12 feet of water. The first bucket is very rough on a high velocity bullet. Three feet of water will make a blacktip 50 BMG AP bullet flip over and separate the steel core from the jacket. Other testing I have done: The smaller baboon above was sitting on his haunches chewing on a large palm nut held at upper chest level. I shot him in his nut. Clean pass-through of nut by S&H SHARRC Velohexploder, .395/310-grain at about 2700 fps impact velocity, a real nutbuster. Last meal: | |||
