In honor of John Parker:

Jason did a great job on his revolver.

I like your Freedom 500 JRH. I own a 5 1/2" Freedom in 500 JRH it is the first one ever built. It is the one that Buffalo Bore used to develope the factory loads. Grizzly Ammo has my BFR 500 JRH developing their factory loads now

I prefer the 5 1/2 to 6 inch barreld revovlers

After chronographing some of the lighter bullets, and seeing the velocity variation, I'm going with heavier bullets, at moderate to slow speeds.
John Taffins' table with velocity variation in the .475 sold me on full figured bullets being the way to go in these calibers.
I bought 200 rounds of .500JRH 440's at 950 fps, and, I'll be shooting them soon. I'll think about about giving the .475 barrel reduction.

Does make it easier to tell them apart...

Been preaching that for years and it holds true in rifles as well

Never said that one can't get good accuracy with light bullets

I shot that revolver and it's rather lively with the 425 grain loads! Great piece!

Nice FA 83, Greg -- and yes, Jason's is gorgeous -- he sent me photos of it right after he assembled it. It's quite stunning!

They are all nice pieces.And FA makes an attractve gun,but that piece of Jasons would make me loose my mind,and sell things not for sale,probably even my house,so I could live in a tent and own that amazing piece.You all laugh but for some reason that thing is calling my name,Hey stupid!

Very sweet gun GS! He did a great job.

Did you buy Jack's custom .500JRH BFR?

I shot that gun, and really enjoyed it. I was surprised that the buffalobore ammo gets full velocity out of that short a barrel. It was boring. 950-950-950-1350-1350-1350-etc.

Have you ever had the 425's jump crimp, when fired in a shorter barrel?

I wish I would have had a red/orange insert put on the little gun.

I got between 1,412 and 1,450 out of the 425 grain Buffalo Bore loads out of my 6.5-inch BFR. That load is hot. Shorter barrel won't make 'em jump crimp. I don't know of any of that ammo ever jumping crimp. Tim Sundles puts together great ammo. From a recoil standpoint I have found that the longer barrels enabling loads to get attain more velocity tend to kick harder.

THAT is WEIRD.
That day we shot a short barreled, .500 JRH. The 425's ran 1250 fps, IIRC.

Then we used Jacks' gun:


and it ran right on the numbers with both types of ammo.
Then we went to a David Clay 16" rifle, IIRC:

In .500JRH

and both of the rounds showed no improvement in velocity, staying at the rated 950 and 1350 fps.

Perhaps you have a different batch then the ones we shoot that day...

BS

There is only one batch of the Buffalo Bore factory loads

I too find it hard to believe that a 16-inch barrel and no cylinder gap wouldn't show a pretty sizable increase over the revolver. Check your notes again!

THAT WAS THE RESULTS THAT DAY.

You're selling but I aint buying.. I have chrono'ed quite a few of those Buffalo Bores loads in my FA 5 1/2" barreled 500 JRH and the mid range load went almost 1000 FPS and the full power load went 1375 to 1382 FPS. None went as slow as the advertised speeds, which is par for the course for BB ammo

quote:

1-Anybody remember what Tim used for a test gun?

2-297 is the powder used, yes? Anyone loaded with it, or know how fast it burns?

3-I'd just loaded 525's with 28-30 grains of 4227, and they went 1350 fps:

1-Yea, my FA 5 1/2" revolver

2-No one except a factroy has loaded it since it is a non canister low flash powder

3- When did you start rteloading? You use factory ammo, because you don't reload. Remember posting that?

quote:

1. So that would be the gun the ammunition was optimized for, right?

NO, how the hell does one optimize powder for a particular barrel lenght?

Oh Geez. Here we go again.
Belittling must be a passion for some people.
Peter.

And posting inane comments the passion of others.....

I can only say the .500 JRH is one NASTY gun. Whitworth has the figures and we did get some pretty high velocities. My hand loads started low and got better and more accurate as they stepped up, still more work to do with my boolit but the DT 400 gr boolit was very accurate with my loads.
My 36" rubber mulch filled boolit trap is again destroyed. I never seen anything like it. The internal pressure peeled out the large nails in the back board and actually bent 3/4" plywood like a flapjack. Rubber was blowing out the back so I had to back it up with my steel trap.
If anyone thinks they need more power and a larger caliber then the JRH, I have to ask WHY?
Stick this thing in a light gun and you are way over the control limit anyway. If you want to hit anything at all make the gun the right weight. Whitworths little .454 on a RH is so bad it is worthless even for a backup.
I keep seeing lighter guns with shorter barrels in the large calibers and have to ask "Just what do you do with them except brag?" One shot that is nowhere near where you aim and pain that makes you quit after one shot shows little common sense. Some of you think you can shoot 1" groups at 100 yards with a 4# .700 Nitro Express! Maybe from a keyboard in the hospital!

I am waiting for a .500 S&W in a Derringer!

Would be nice to go back and try it with another chronograph...

Jack has bought another one, by the way. Same model, or at least looks like it.

How close was the chronograph?
The picture shows the gun being aimed down, so just wondering if it was too close and maybe you were clocking the muzzle blast?

I was testing some 320s in my 4-5/8" 45Colt Blackhawk and the chrony was reading a fairly consistent 1500-1550(ish)fps at 7 steps from the bench.
I moved it out to 10 steps and started getting the expected velocities of around 1200ish.(this was many years ago and I don't remember the exact numbers)

If the chrono was too close, that may explain the weird numbers from the different pistols and rifle.

My notes are right

No your notes,eer I mean memory is incorect, I spoke with Jack today and they did not all chronograph 1350 and as expected the reifle was indeed faster

I f you enjoy reading post full of inaccurate BS drivel, by all means carry on and feel free to just ignore the posts that challenge the BS drivel with the correct info

GS, I love that last gun!
No need for a barrel.
The others can be shot all day with a spike stuck in the ground! Sort of like the M1 with rifle grenades.
Of course when I was in the army I fired the grenades from my shoulder.
C'mon fellas, how about movies with you shooting those things, that would be fun.
I might be nuts but I don't put my hands under car tires either. Some of those things will split a hard hat.

I really like that levergun!
