In 1984 I bought my .54 renegade, I shot it many years deer hunting. I shot 430 grain Maxie balls. At first I used black powder, then I switched to Pyrodex and it closed my group up some, after that I switched to Pyrodex select and it closed my group up even more. In the end I ended up with a 2" to 2 1/2" group at 100 yards. Then I switched to T/C 3 piece sabots with 240 grain nosler JSP, I got solid 1" groups. I killed many deer with this set up. Then I bought me a T/C pro hunter a few years ago, I used pyrodex select in it also and got good results, nothing wrong with it at all. I have recently switched to BH 209, clean up is easy compared to Black Powder and other substitutes and accuracy is repeatable. If the wolf NW shoots anything like the Posts I have read about accuracy and shooting conicals, I don't think you will have any problems. Do what mountaindevil54 says and you won't have any problem. If you do call CVA & tell them what kind of powder and loads you are shooting, they will be able to help you, along with members of this forum. For greatest accuracy I would recommend cleaning between shots with a T-17 cleaning patch or a pre-saturated CVA cleaning patch, then a dry patch then loading for the next shot. Good luck
