i have a short cva sidelock kit gun i bought at service merchandise many years ago,any more powder than 70 & you cant hit a pie plate at 50 yards,70g & you can ring the bell all day at 100y.i have another cva that is a inline made about 95-96 that dosent like more than 70 with a round ball,i reckon it blows the patch before it exits the barrel,barrel dia means a lot with any type of muzzle loader. i have found it costs much $ to play around with the diffrent loads so now when i find 1 that works for me i try to stick with it,i helped blood trail a deer that had a 250g shockwave ran thru it from the front chest cavity till it came out the ham ,it went 1/2 mile before my buddy caught up with it ,i think a powerbelt would have killed it dead within 100y or less,hard to say but id like to try it & find out :) ,mike243
