Had a strange experience today at our local trap shooting match. I mentioned that I had devils own time getting plastic out of my barrel from a practice we had the week before and finally ended up using acetone. None of them appeared to worry about this, though some guys said they did clean their shotguns after a match or practice none of them appeared to worry about plastic. Several guys said they hardly ever cleaned their shotguns and two guys even showed me their shotguns. They were apparently telling the truth. What's the deal with this? I've heard this argument applied to 22's but didn't think I would hear it in relation to shotguns. Is it important to clean after each match/practice? Fred
