| 475 linebaugh + H110 + 400 gr cast / what load? | Login/Join |
| One of Us |
I'm trying 25 gr of H110 behind a 400 gr cast bullet seated out to 1.8. this doesn't sound overload, does it? if you have any other loads with this powder and bullet weight, I'd like to hear them as i can't seam to find load data for the 475 linebaugh. | ||

should work fine. go up slowly from there though | |||

26 to 26.5 is where it will start to come together, either H110 or 296. Use a LP mag primer. 15 gr's of HS-6 is super accurate for a lighter load. | |||

A Google search will turn up lots of .475 data........ Here's a couple of places to start: http://www.sixguns.com/tests/tt475.htm http://www.reloadbench.com/cartridges/w475lineb.html Grant. | |||

bfrshooter and I developed a really nice load for my .475 and that is 26.5 grains of 296 behind a 420 grain WFN -- it's very accurate. "Ignorance you can correct, you can't fix stupid."

my linebaugh built gun must be a tad tighter as with a 420 grain bullet 26 is max and and even a tad more gives flattened primers and stick extraction. One thing ive noticed about the 475s. they seem alot more pressure sensitive then the 500s or even the 454s. they go from no pressure signs to pounding out cases with only a half a grain differnce in powder charges. So do please work up slowly past 25 grains.

Lloyd, it depends on the boolit and is why a slow workup is important--but everyone should know to work up. I have a 420 gr gas check boolit that looks like all the other boolits I shoot and all are the same diameter. This boolit will max out at 26 gr's. Then I have 430 gr boolits that will go higher then 26.5 with no pressure signs. The 400 gr boolits I have will go even higher without a problem. So not only is there a difference in chambers with different guns but the boolit itself will effect pressures. It is the same as jacketed bullets in a rifle where just a brand change can raise pressure. The .475 might seem tricky but remember we are shooting very heavy boolits and working up near the top to start with. Sort of like using 350 gr boolits in a .44 with max loads. I have not found it to be any different then any other caliber when working within it's limits. The bad thing is a lack of published information, something the 45-70 in handguns also lacks. We are sort of left on our own when working loads. If you research Linebaugh's loads for the guns he makes, you will see they are much heavier then most of our guns can take. That scares me and someone can get in trouble just picking his loads. Working with the slow powders and trying to reduce them to a starting load can get you in trouble because there is so little tested information as to starting loads. Starting too light is more dangerous then working near top to a sticky case. | |||

Well, I dont really wanna work past 25 gr. if anything, I would go down from there to find the most accurate load. I'm shooting a BFR revolver and saw the 25 gr load on the internet for a 420 gr cast and figured it should be safe for a 400 gr cast also because it isn't the max load i saw. I just wanted a second opinion on if anyone has had any problems this this load being to high of pressure. Thanks for all the reply too | |||

Spot on... Also a bullet made from high Linotype will reach peak pressure faster than a wheel wieght water quenched bullet from the same mold In My Experience.... _____________________________________________________ A 9mm may expand to a larger diameter, but a 45 ain't going to shrink Men occasionally stumble over the truth, but most of them pick themselves up and hurry off as if nothing had happened. - Winston Churchill | |||

Gohip, don't worry about the BFR. It has to be the strongest revolver ever made. Just work up slowly. If you get a sticky case, back down 1/2 gr. If you work for accuracy, you will get there before any sticky cases anyway. My brass falls out of my BFR. Be VERY carefull working down with the powder charge, more dangerous then a slightly sticky case. If you want a lighter but accurate load, use 15 gr's of HS-6. It will do around an inch at 50 yd's. My WFN 420 gr with 26 gr's of 296 has done 5/8". With 26.5 gr's it will do an inch out of Whitworth's converted SRH. Zero pressure signs. | |||

ok, that load seemed pretty good. I shot a 2.5" group at 30 yards. I need more practice. the kick wasn't as bad as I was expecting, but you could definately tell it was powerful. I wouldn't feel comfortable shooting a deer past 25 yards yet, but hopefully that will improve to 50 yards with practice. I've got another question. after firing and reloading the revolver a few times, it became sticky trying to load a round into two particular chambers. extraction was not sticky, but loading, I had to push with a little force to get two of the rounds to seat to the rim. I also noticed kind of a blast pattern on the rear of the cylinder like what you would see on the front between the forcing cone and the chamber. It's just not as pronounced. Is this normal? | |||

with 110 i wouldnt drop much below 24 and make sure your using a good primer like a cci 350. As to alloys in my experience a soft alloy will reach peak pressure in a barrel sooner then a hard alloy. Lead has very little resistance going down a barrel no matter what alloy it is and a heavier (softer) bullet will create more pressure then a light (softer) one. If you are a beliver in the fact that a bullet bumps up to fit a barrel then also a softer one would create more pressure faster as it would bump up and seal the pressure faster. Gohip if you want to load lighter then your 25 grain load id suggest you pick up some 2400 or hs6. there ideal powders for pushing a 400 to about 1000-1100 fps in the linebaughs | |||

With a load that is too light, the brass does not expand to seal the chambers, common with slow powders. You will get blowby and boolit lube in the chambers making it harder to chamber the next rounds. It is nothing to worry about. The reason to work UP, not down. I don't know why anyone buys a cannon and then looks for lower velocities? If you want slow, use faster powder. | |||

well, I was under the impression that 25 gr wasn't a slow load, but closer to a top load, but everyone seems to think it's a low load. so I guess I should load hotter? I wasn't talking about loading down to 1000 fps, but just a grain or so to try for better accuracy. I guess i will only load up cause 25 gr seems to be a mild load according to everyone. maybe I'll get a better seal with a little more powder. | |||

gohip, I know they aren't that pleasant to shoot, but 26.5 grains of 296 seems to be where mine (warning -- work up at your own risk -- I had to throw a disclaimer in there) is happiest from an accuracy standpoint. It certainly kicks, but you just need to practice, practice, practice. It's like a big-bore rifle in that you don't just pick it up and shoot well, you need to work up to a level of proficiency.

oh, it wasn't really un pleasant to shoot (as I thought it was going to be before this range session), i just need more practice with handguns in general. I did notice my most accurate shots were withing the 1st 10 rounds. I shot 40 rounds at the range and didn't get a blister on my palm like I did the first time I took it to the range with 480 ruger loads. I can shoot it now and look forward to taking the next shot. I just have to get more accurate. I can't wait to take a deer with it though. I hope to extend my comfortable hunting range from 25 yards to 50 this summer. I'll have to work my way up to 26.5 grains cause I guess I'm showing signs of low preasure at 25 gr. I did notice that my BFR has an extremely long cylinder that would allow me to seat heavy bullets way out. I don't think I need anything more than 400 grains though. | |||

You sure don't need heavier then 400 and the Lee 400 shoots great. The reason my boolits get to 430 gr's is because I made my own molds and I never know what the weight will be.I have shot up to 460 gr boolits and everything from 400 up will shoot. | |||

And his 420 grain WFNs are a piece of art! "Ignorance you can correct, you can't fix stupid." JWP If stupidity hurt, a lot of people would be walking around screaming. Semper Fidelis "Building Carpal Tunnel one round at a time" | |||
