Additionally, there's a BIG differencein recoil! Given an 8.5 pound rifle, a .54 with a 230-grain ball and 115 grains of powder gives 32 Foot/Pounds of recoil at 1700 FPS MV. A .58 of the same weight firing a 270-grain ball at the same MV, using 140 grains of powder, has 48 Ft/Lb of recoil-an increase of 50% over the .54!!

Wouldnt 140gr of powder be a little too much?

50% increase in recoil? 32x2=64.

Out of a 1-70" twist 58 caliber is it possible to get it shooting ball-ets with a little work?
Also, I have been looking at GM barrels. Anyone know of any other good barrels that would fit a Renegade? How about with a twist a tad bit faster than 1-70". 1-60" or a 1-48" would be better I think. Then you have bigger variety of bullets.

Some guys on another forum say the 58 with a 1-78" twist and a round ball is fantastic. They really really really love the caliber. They said the recoil isn't too bad and it will take down anything in North America. They said it can drop Elk and deer in their tracks.

The .58 caliber Green Mountain Barrel with a 1-70 twist is all the rifle you would need to hunt anything in North America. Shooting a 284 grain .58 caliber roundball is a monster chunk of lead when you consider many people are shooting a 240 or 250 grain .45 caliber projectile in their sabots. Roundballs are deadly. They have been killing critters for many years and will continue to do so for many more.

NOT if you consider the old-time Hawken load formula to be correct - in a .58, half the weight of the ball would work out to be about 140 grains.....

Twice 32 is indeed 64, but that is doubling it-in other words, a 100% increase from 32,not a 50% increase.......

IS there such a thing as a .58 cal. ball-ette? I believe any bullet that is no longer than 1.5 X the bore diametrer will shoot OK from a slow twist. After all, the U.S. Springfield rifle-musket of .58 caliber has a 1/72" twist, and it shoots 530-grain conical hollow based bullets quite well (Minie Balls!).

Buffalo Bullet Company does make a 405 grain ball-et with a hollow base and a hollow point. I shoot them out of my 1-70 twist Green Mountain Rifle with very good results actually. I up 90 grains under them and they will really rattle the steel bullet trap when they hit down range.

Sounds good to me! I am getting excited. I would like a 58 before next September! Cayugad can send me his to barrow. Just kidding:D
