Dan,

I orignally asked the twist question because I had a line on an 8 bore underhammer with 32" 1:48 twist. Since that time, I purchased the rifle because I really like the simplicity of underhammers. With this rifle, I have shot round balls into 3 shot 1" groups at 50 yds with 150 FFG Swiss. I will try 175 next and then 200. Regardless of the twist, if they are accurate and velocity is not substantially diminished, what's the difference if the twist is fast? I have also shot 1350 grain conicals into 1.5" at 50 yds with 150 grains of FFG Swiss. If the 1350 conical and ball are both pure lead and the conical is 1.65 the weight of the ball, what's the disadvantage of a conical rather than a PRB? Having said that, I prefer PRB and will shoot them in this rifle almost exclusively - just because I like them. Does anyone know where I can buy .835 balls? I'm not into casting yet. Thanks, PJB
