A comment in my last thread about accuracy got me curious. It seems like the norm that the first shot out of a clean barrel never hits exactly with the rest. I know it certainly doesn't in both of my CVA's. This is my first year using BH, so I'm curious if I were to fire a shot or two before loading up to hunt, how long is it ok to leave the barrel dirtly like that? I've been meticulous about cleaning them after each range session, but it irks the crap out of me that the first shot never hits with the rest. I'm sure I could fire a shot or two the day before, or the morning before I hunt, but if I don't take a shot, how long is it okay to leave a barrel dirty with blackhorn?
