Hey guys, I'm brand new to the realm of long distance shooting, and I've heard a lot of mixed reviews on gun cleaning habits. I was taught growing up that keeping it perfectly clean was the key to accuracy, but recently I've heard of some folks leaving it for a few hundred rounds, and then wiping it out but leaving the copper fouling in place, insisting it is more accurate. I've been a bit wary of trying new ideas like those, just because I don't have the funds to ruin my rifle with poor maintenance habits, so if there are any tips or tricks from those of you with experience, I'd appreciate it. Right now, due to an extremely limited budget, I'm running a Browning BLR in .30-06 and getting 1/2 MOA groups out to about 600 yards, then they start to spread to as much as 1 MOA around 1000 yards, which I'm pretty happy about given the setup, but if cleaning it differently can improve it at all, I'd appreciate the input.
