The powder is fine though I like 777 better because it cleans up better. I haven't been happy with the shockwave bullets shot 2 deer withem and they exploded befor penatrating both were H/L shots and both required 2 shots. I've had great success with 295 gr powerbelts and highly recomend them. When I clean my bp gun I use patches till they come out with verry little blk on them then put a oily patch then a dry patch and set the gun barrel down for 3 to 5 days.
