Thanks for the responses! T/C fan, glad you brought up the muzzle brake thing, because I was wondering how much this would help. Unfortunately no bottle necked cartridges are allowed in Iowa and the only rifle allowed is a muzzle loader. For that I've got the 209x50 rifle set up on the Encore. Of the straight walled choices, it boils down to the the three listed calibers for me, as far as a handgun cartridge. After reading these posts I've decided on a muzzle brake and guess I'll have to keep my eyes open for the best deal I can find on any of these calibers.

Thanks again.
