I could not imagine firing off that round with out ear plugs in!!! I think it would make your ears ring for a few days.....
I did test IMR 4198 31 gr cci 250 and a Badman 405 gr cast boolit and a 3 shot group of 3/4" @ 50 yds only 1060fps but should kill any deer that it hits....
I had good accuracy with4227 but went away in cold temps looking for a substitute myself
Yeah so far I've only been able to test in the heat of summer... 2400 was strong for the amount used but accuracy was poor.... So far blue dot, RL7 and 4198 has been far performers ... There is no 4759 anymore so we has to come up with a new solution for our rifle pistol....
i hear of this amazing accuracy in the BFR but I'm still to see it for myself... Asking 1" at 50 yds isn't looking for a golden eggs in the world of accurate pistols...
They use Trapdoors for shooting poultry, like chickens?Originally Posted by Ramjet-SS
I think that poultry trapdoor load almost kill off the American buffalo..
The word is P A L T R Y.
Well, you are finding out about case size versus barrel length. Good teacher to try and solve it.
Why I cringe with a 2" .454 or a 4" .500. Not much more then 10 yard guns with a huge blast.
Guys buy great guns and get them whacked off first thing. Kool factor and balance with no regard whether they can shoot. The big excuse all around is sight radius. Not so, you need a caliber that will shoot with a short barrel and some do.
I don't know what to do about powders. We are hurting with powder losses. There are no direct substitutes for any powder. Burn rate charts are dart boards.
See you do not need those top end loads especially for poultry , just as I said, but if your ego needs them by all means load away.
Who Was talking about top end loads? Can you give a "for instance"?
Loaded 5 rounds of 38.0 gr 4198 and a 300 gr Hornady JHP as my test load...
the 405 gr with 31.0 gr of 4198 has proven to be the most accurate with .5" " 50 yds..
1060 fps...
You know what bullet is a dandy deer hunting bullet is the Lyman 457122 hollow point mould. It has worked outstanding for me from my Encore. The load was a 30.0 grains of XMP-5744 Large a Rifle primer.
What is the weight of that bullet and the velocity?
322 grains from my rifle it runs 1405 FPS but I have taken deer with that bullet running 1200 FPS loaded over a load of Unique. It is the Gould design much history behind that bullet an design. Now at lower velocities I alloy accordingly.
XMP-5744 has the same burn rate as SR-4759 have you ever compare the two.. The 4759 is no longer made so I wonder if the 5744 would be a equal substitute....
I did try it and it does not compare. I don't know what I will do with the rest of it.
I have both powders and have compared them of course the 4759 fills the case better (bulkier) however the velocities and accuracy was very close. so my findings are different than 44man.
XMR 5744 falls right in line with 4227 and is slightly slower than 4759.
Tested these loads today
300 gr 4198 38.0 gr load shot 1/2" at 50 yds 1340fps
405 gr 4198 31.0 gr load shot average 8 shots of 3/4" at 50yds 1060 fps
405 gr RL7 35.5 gr load shot average 8 shots 1 1/2" at 50 yds 1210 fps
all of these loads shot good enough to hunt with... I think the 405gr cast would be the bone crusher....
Man the gun seems to love those 405s at all velocities. Some fun work you have done the favorite part of any new gun is load development and of course all the shooting that goes along with it.
The BFR will handle a wide range of boolits, here are some I shot, from 300 to 485 gr.
One of the boolits gave me 3/16" at 50.Attachment 145551
The large group was 10 shots with my normal 317 gr.
Sight in target on the right was 5 in 5/8" then 5 in 5/16".
MR hit it as good as can get with the 1 in 14" twist. Allows for the reduced velocities.
My best group ever was 2-1/2" at 500 yards.
I just never shot a 45-70 rifle that can touch it.
I also shot these groups with the Ultra Dot. I don't know what it would do with a good scope.
Too bad all was with 4759, burns so clean brass does not need cleaned. 5744 did not do this and it is dirty.
The only difference to what you get is I have over 20# of 4759!
However mcal is doing very good with what he has. He has the gun under control. Very hard to get what he is getting with powder choices.
I read the warnings about the powder going away and called Midsouth, they took a back order and it was a few months but 16# showed up. A friend had given me a big can of it, still the old metal 5# IMR can.
It was not sold by the pound long ago, cans were 8oz. Too bulky for 1# cans.
Yup BFR are good guns my 10" 30-30 is tack driver with everything I feed it.
I have great performance with 5744 in th 458 SOCOM as well.
