Home Forums Hunting & Shooting BPCR 45-70 vs 45-90, -100, -110, ets

Greg no problem with the slick barrel, just shoot some pyrodex and don't clean for a day or two.... problem solved.

Yer Hunney will go into shock that ya AIN'T blamin' me!!!

Oh she does pard BIG TIME She gets real nervous whenever she sees me on the puter with the plastic in hand!"OK now what you gotta have for that "watcha ma callit" rifle that Jim talked you into!"

I would hazard a guess that if'n you had a large pic of my mug, it would end up as ground zero on her dartboard!! Then SHE would get to see how tight a group she could get!

Don't know about that but I do know she covets your Buffler robe!

What Buffler robe?
That hairy thing was just ET with his shirt off.

NOW you have your "in" Tell her dere is only one way to git a buffler robe and that is to go kill a buffler wid a buffler gun

Ya mean this??

GTC--I don't know how Al Story's "Borchardt Chamber" is configured, so I can't make a comparison.

A friend of mine has two original Sharps barrels taken from Borchardt military muskets. We did chamber casts of these and used the casts to spec a reamer to cut that chamber. My 45-70 Business Rifle has its chamber cut like those originals.

That is where you guys Luck Out bigtime Bill. There ain't many od Sharps around here as compared to the central west from Texas to Montana. In fact I would have a doubt that there are very many 44-90 barrels around to make a good reamer from (Our compadre Kurt IS a lucky [bleep]-he had one)for the new rifles' chambers. I don't think there are very many 44/90 men out there.

Maarty don't remind me probably have to see that at antelope camp this fall ........and the tiger

10-4 Ranch, and it may not be advisable, but before I learned of the powder compression dies, i loaded my 120 with FFFG, and the 540 GG bullet, accuracy was excellent, and uniformity was within 8 fps with an average of 5 shots.

Dont all grades of BP have relatively the same burn rate, power or pressure is controlled with granule size?

And after spending a few days with ET at the boar hunt, I gotta give PP bullets a very serious and determined try.

Gunner

The more F's the faster the powder burns, the higher the velocity and pressures.
Biggest problem with going with the smaller powders in the big cases it burns hotter heats the barrel up quicker and can cause some really serious fouling problems.
1f would be my pick of the liter in the 3 1/4, plenty of velocity and hold the recoil to more manageable levels, with likely less hard fouling.

Preshade it Ranch, but if I use my new powder compression die, do you have any idea what [F]or grade the FG may be ground or crushed to after i compress it?

Gunner

It'll be ground to flour just like 3f is, but due to the bulk of the powder coming from the can you won't be able to put as heavy a charge in with the 1f as the 3.
With my Lyman 55 measure, if I set it to throw 68 grs of Goex Cartridge, it will also drop 70 grs of 2f express and 72grs of 3f express.
If I were going to shoot 3f in the 3 1/4, I'ld only use enough to just make firm contact with the fully seated wad and bullet, maybe no more than 1/10 or less compression.

Thanks Ranch, I have some Goex FG, but when I have time I'm gonna drive up to Clarksville Arkansas, ang get a load of the KIK powders as well, my rifle sure like Swiss FFFG through a drop tube and the 540 GG at 1500 fps.

The PP bullets wont be seated very deep in the 3 1/4" case, so the bigger granulation will indeed help.

Gunner

Oh hey Ranch, do you guys measure by weight or volume?

I set the measure by weight and then let it load the volumne. When I use FFG Express,I get a nice balance between the volumne,power and fouling.

Thankee much ET, you do know your responsible for my attempted surgery on 9# Onion paper today dontcha

Gunner

LMAO
