Straight from the CVA Instruction Manual: Round ball and patch loads are not recommended for CVA Break-Ac- tion In-Line rifles. The fast rate of rifling twist (1:28) associated with CVA Break-Action In-Lines may not provide optimum accuracy when using patched round ball loads.But hey your mileage may vary if all you want to do is shoot the rifle and hear it go bang. Reducing the powder load has nothing to do with spin rate the ball is still in a 1/28 barrel and the ball is going to over spin and be inaccurate.
For just target shooting and deer, I'd recommend Hornady XTP bullets. You can use 44 or 45 caliber with the appropriate sabot, which you buy separately. They are actually meant for handgun cartridges but work great for muzzleloaders and are economical to shoot.
