All this hostility? What is the matter? Paul, what kind of an engineer are you, Civil? I am only a lowly mechanic and I can figure this stuff out. You state I am full of BS, prove it. Seriously, in engineering terms explain to this old mechanic, how the combustion process and expansion of gases in a rifle barrel during the firing of a bullet IS NOT governed by the "First Law of Thermodynamics". Step up the plate, and tell us how it really is since I am so wrong.
Come on, don't be shy. Tell us all! Oh, please spare me the BS about "how I have melted down". No I haven't I just expect to be educated by those that have stated I am an ignorant man, and full of the so-called BS.


To the rest of you.
The only requirement I have seen here at AR to qualify as a big bore is that the bore must be equal to, or greater than, 0.375". So I am a big bore shooter with my 50 Beowulf. Stick that in your pipe and smoke it, children.

I don't have to prove you're full of BS, when you do a much better job than I ever could.

I remember in grade school a kid would occasionally get a "kick me" sign taped on to him, and after one or two kicks in the butt, and all the attendant giggles, he'd figure out what was going on. I never remember a kid that would make his own "kick me" sign and tape it on himself, then wonder why he was getting kicked, and ask everyone to prove he had a "kick me" sign on him.

I don't know if that is too subtle for you. First time I've been accused of being civil.

Paul,
I think the B.a.S.s_clot tatooed "kick me" in the mirror, itself..

So, now it's no longer a german national (the original Posuer ID/member number has PM'ed me as axel, teg, and 500ahr) and it no longer married to judy... it's from some southern state... (his mind went south, that's certain) and it has a 50 beowolf.. but not a big bore rifle to talk about.. but he sure does say "in my experience" about alot of topics...

Come to think of it, I think it had a neon sign installed on it's back.. "kick me" ... guess where it shoved the power supply

Paul H - I think you explained the Ass Clown's latest folly in terms even a small child should understand. Apparently Scott Sweet doesn't rise to that level. I'd crawl into a hole and shovel the dirt in on top of myself if I'd made a fool of myself as often as "Le Clown."

Paul, that is because you CANNOT! I would have to be full of BS to begin with.

Your profile says you are an engineer, so I ask you, what is your discipline?

jeffeosso,

By Saeed's definitions for this forum a 50 Beowulf IS a big bore.

Ed,

Serious question. Why do you like heavily compressed or compacted loads? The 600 OK can easily reach 2400 fps with a 900 grain slug without the need for heavily compressed / compacted powder charges. Simply shifting to Rel 15, VAREGET, or IMR4064 will get you there with an approximate 97% to 105% case fill depending upon which powder you use.

At least in my experience "touching" (99% - 100%) to slightly compressed (< 102%) loads have been the most consistently accurate.

Just curious.

By the way, any progress on the 12 gauge Savage?

This is an interesting flip flop for you Ass Clown.

You've been pissing and moaning and doubting practically everything said about the 600 OK all over this website, even though you've never laid eyes on one and likely never will. You mouth off with your clueless crap like:

Quote:

This sight is full of overly optimistic ballistic data, the only reason I can comprehend for it is personal ego. ASS_CLOWN




Now all of a sudden you capitulate and reverse yourself 180 degrees and say the 600 OK will EASILY do 2,400 fps.

Why don't you just admit the obvious, that you haven't got a clue what the rifle will or will not do, and then sit down and shut up? Is that so hard for you? Or are YOU the one with the "personal ego" problem?

Re: Shooting the .600 OverKill [Re: GeorgeInNePa]
#655270 - 05/10/04 09:51 PM Edit Reply Quote



GeorgeInNePa,

Very nice!!!!

Here is what the software says for your loads. The calculated case capacity was 211.7 grains of water. COL was taken as 3.75"

150 grains of IMR7828:
Muzzle velocity - 1762 fps
Muzzle energy - 6197 lbft
Chamber pressure - 27,223 psi (max avg)

155 grains of IMR7828:
Muzzle velocity - 1810 fps
Muzzle energy - 6545 lbft
Chamber pressure - 27,873 psi (max avg)

160 grains of IMR7828:
Muzzle velocity - 1858 fps
Muzzle energy - 6895 lbft
Chamber pressure - 28,458 psi (max avg.)

Not up to 600 NE levels yet, but still impressive. Pressures are nice and low too. Analysis suggests a better powder selection would be one of the 4350s or Rel 15 for 600 NE power levels. If you want to really rock and roll go with Varget, IMR4064, 4895 or IMR3031. These will push your pressures up into the 50+ ksi range and the velocities get REAL impressive. So will the medical bills I would wager.

For instance:
155 grains of IMR4895
Muzzle velocity - 2451 fps
Muzzle energy - 11,991 lbft
Chamber pressure - 56,357 psi (max avg)

Post Extras:






Since you have "45 years of reloading experience" ,at least you do according to jeffeosso, you should realize that it is the powder selection more than anything else that will get you the muzzle velocity. The simple truth is that H414 is too slow to get to 2400 fps with a 900 grain bullet (unless one HEAVILY compresses it), and there is NO WAY that IMR7828 is going to get you there. There are better choices! If you have not learned this yet in your "45 years of reloading experience" I don't know what to say.

By the way, the aforementioned load data was calculated before George posted the chronograph results. I would expect that the IMR7828 loads above may run about 15 - 20 fps faster. Same for the IMR4895, although I should wouldn't start out with 155 grains as the recoil may shatter the stock and the thrust force more shear the lugs, fracture the abutments! Then that is just me.

Now why don't you go crawl back to the "Political Forum" were you belong.

In all the thousands of rounds I have experimented with,

those jackass powders, stretch the brass twice as fast

as larger loads of ball that will do as good and in my cases 2% better.And those pressures not only come quicker but spike a little higher which is hard on stuff.And the OK is similiar to my cases.Jackass powders get to peak pressure in less than 2/3 the time the right ball powders do, but they don't have the area under the curve denoting total energy compared to the ball powder.My

first requirement in what I do is max case strength and life, with the greatest power if you want it...Ed.

Ed,

I agree completely with what you are saying, I am just curious about accuracy.

For the record I have never shot loads more than ~ 110% - 112% (10% - 12%compressed) and they did not show the accuracy of the ~ 100% loads. That isn't to say that they weren't acceptable for hunting.

Another question. How do you keep the bullet from "cocking" while compressing such heavy loads? I had serious problems with this, and suspect that it may have had something to do with my reduction in accuracy. The SD of the loads in question was not bad (in some cases better than the 100% loads) but the groups had opened up considerably (around 2X). I figured either barrel harmonics had gone to hell (working pressures can do that to you) or it was the "cocked" bullets, or a combination of the two.

My little wildcat would do 2" 3 shot group, once in a while, a few years ago with scope, when my eyes were much better.The load compresses nicely with shaker on the press, while seating bullet.Ed.

2100, 2200 ,2300 ,2400fps who cares? I think 450 grain bullets at over 2100 fps will do the job on anythink I can think of. 900grains doing the same fps must be well "overkill"
I see the point of the whole thing is Rob designed built and fired this beast from start to finish. That is quite a feat in my book. I have enjoyed reading the posts from the start; enough so that I have started one. I think its great George also is sharing info with us all.
I doubt if I dont screw my project up that I will even push it over 2200fps but Im thinking that would be just about enough.
Good show George I only hope I can build a working 600OK that looks 1/2 as nice as yours!
Talked to pac nor last night they have my barrel and are threading it for the Enfield and while they have it taking it to 24inches. I have the action 90% inletted to the wood. When the barrel is back ill give head spacing a shot and finish up the feed work. If I dont screw anything up I hope to shoot mine before fall. If I mess up I will be looking for a Smith that will mount my barrel to another Enfield action I bought. George Your guy do that type of work? Or only entire weapons?
Dean




Dean,
Do you mean if you screw up the head-spacing? Rob has the only reamer, so you'd have to talk to him. Unless Pac-Nor still has it. They install barrels too, don't they? My gunsmith does everything, I can IM you his email address if you need it.

Ed,

Thanks for the info. Did you ever test your wildcat for accuracy with one of the faster powders?

I was seeing increases that took ~ 1.5" to 2" groups up to the 3" - 3.5" range. Again that ain't bad enough to not hunt with (unless you are a long range hunter).

Since I invented the .600Ok let me state a FACT THAT ASS-CLOWN can't REFUTE. The .600 OK with a 26 inch barrel will hit 2400FPS with a 900 gr bullet! Been there, done that! I have two GUNS in.600OK and each will hit that level of velocity!I would be happy to let you shoot that load, in fact it would give me great pleasure to see it knock you senseless(even though that effect may be hard to clinically diagnose in your case)! I also have a 26 inch barrel on each gun which gives me a 100 plus fps advantage over a 23 inch barrel. MAKE SENSE? EXCUSE ME ASS-CLOWN but since when do you OWN a .600 OK or.600 NE or anything over a .50 Beowulf? Where are your facts derived from a computer program you created? I know you don't have the smarts or education to write a computer program of any type much less a sophisticated ballistics program! Even then, they are just simulations, facts are facts!You probably just have some crapy program you stole off the web! Again Ass-Clown where are your CREDENTIALS? They don't exist do they?Now pay close attention! Focus, Concentrate. STOP TALKING about GUNS YOU KNOW NOTHING ABOUT! If you don't OWN one and/or have even shot one what in the world makes you think you qualify as an "expert"?-Rob

Ass-Clown- 60KPSI is beyond the design criteria I set for the 600 OK. My calculations and those done by others suggest that the CZ has an adequate safety margin, but I'd prefer to keep it below 55KPSI. You are correct in that Rl-15 and Varget will drive a 900 Gr bullet to over 2400 fps in my guns.I do not publish the actual loads that do this due to concern over how others may use them. As I've said before the recoil/torque of the gun is ferocious at these power levels and a person inexperienced with recoil like this may be seriously hurt. Heck, I'm not totally able to control it! 1900-2200 fps will keep the majority of people very entertained IMHO! I accept your apology!-Rob

Um...HELL YEA!

Seriously, it's not terrible at 2150fps. Pleasant? No. Controlable? Yes. Painfull? Not really. This coming from someone who has fired a .458Win a few times and has a few hundred rounds through a .416Rigby. I think I can handle 2200 to 2250fps. I'll know next time I shoot it.

Of course now that I have a .600 and a .416, there is a BIG gap in my selection. I need something in-between!

Robgunbuilder,

I hope now we can, at the very least, converse in a civil tone to one another. By all means, if I slip up and start acting the jerk, please tell me off post haste!

By the way, I have NO doubt that the recoil of a 900 grain bullet going 2400 fps is violent, to say the least! Ouchie!!

Regards,
ASS_CLOWN

George,

To fill the gap maybe Rob can design and develop the .500 Over Kill. There might be something similar but I'm sure Rob can successfully build one.

No need to just stick to the .50 BMG and this Robar then you have all the overkill you want
Slap ammo for more speed

DOS? DOS is not extremely outdated... until you are running a program on a old(1) *nix(2) box that has sourse with .cbl on the tail of the names which the company that made it doesnt even know who wrote it anymore.(3)

then we will talk about outdated.

dont mind me just venting about a place I used to work.... speaking of which anyone got a job for a 26yo computer geek? i work cheap


1: it was UPGRADED to a dual 486.
2: SCO unix version 3(? i think)
3: its true. they had no record of the programers name or when it was written, in fact we were the only people that they knew of still running the system
