What Projectile

[WI Smoke]

What are you supposed to shot out a .54 GPP PRB or conical? Which is more accurate? Was wondering because the friend to my Great Plains Rifle is on its way from Impact Guns. Any feed back about them, this is the first time ordering from them.
Thanks From WI

 

I don't know anything about Impact Arms.....never heard of them to be honest.

Regarding projectile, the PRB is almost always more accurate than a conical and I believe the correct projectile for the GPP. But then I believe the PRB is always the correct projectile in a real muzzleloader.

The reasom I am wondering is that it has 1 in 30 twist Where as the GPR has a 1 in 60 twist.
Correct me if I am wrong but doesn't anything faster than 1 : 48" use conicals?

Pistols use a faster twist, I am told.

 

[WI Smoke]

I know the twist is 1" in 30" but does thast mean I am to use conicals?

The faster twist used in pistols is to offset the lower velocity pistols produce.

The idea is to get the RPM the bullet/ball is spinning to be about the same with both.

For instance, a 1:60 twist rifle shooting a ball at 1600 Feet per Second will spin its ball at 19200 RPM.
( one rev per 60 inches = 1 rev per 5 feet. [1600 Feet per Second/5 feet] = 320 rev per second. [320 X 60 seconds] = 19200 Rev per minute).

A pistol shooting the same ball at 800 Feet per Second from a 1:30 twist barrel will also spin its ball at 19200 RPM. (Note the velocity is 1/2 as fast but the twist is twice as fast).

IMHO the ball is the authentic projectile for an 18th century flinter, but provided with a proper barrel, a conical bullet with it's tremendous bearing surface and better ballistic qualities has the ball beaten hands down. The boys at Wimbledon were competing at 1000 yd. ranges with two balls apiece. Oddly enough, only spent conicals were found downrange after the competition. :grin:

Just read my Lyman manual, they say mot to shoot conicals out of their pistol because of the heavier bullet and there for the recoil may crack the stock.

Thier other reason is that, if the gun is carried, and carried muzzle down, the heavier (and often looser) conical might slide up off the podwer charge. Gun then may = little bitty peices.

I'm going to do it though with my .50 GPP. If I cant get a conical that fits tight and shoots good, I'll try paper patching, which would have the benifit of leaving the speed-loaded ones un-patched, thus easier to load for follow-up, and/or I'll make sure it seated when I get to were I'm hunting, and not even attemp to shoot it if I've been walking without makeing sure its seated.

Anybody ever experimented with a wad on top of a conical? Would it throw the bullet off as it exited? Could a ya get one to fit tight enough to prevent the conical from moving up?
