I have shot a ton of BBI threw my stock barrel without problems, I was cautious at first and checked the barrel after a few sessions. They proved to be very accurate and always available.
I can understand the feeling about the camo and BDU's at matches. I cant say that I would wear it personally, but I feel at this point its more important than every to encourage any and all shooters and make them feel welcome rather than discourage based on what they wear.
I have always said if it stops being fun, ill slack off. It's not hard to see where travel and time away can wear a person down. Especially of they're not shooting up to their own expectations.
I never had a problem with my 35 with a decent trigger, however my 23 with a stock trigger took some time to bring the poi back to the poa. I tried to blame the gun forever but it was me the whole time.
In a gas gun IMHO the 6.5cm outshines the 260 by just a bit. The shorter case will let u seat the longer match bullets and still for the mag and feed ready well. Nothing against the 260 I just think it's slightly handicapped in the gas gun
Only downside to the dpms is the weight, the barrel alone is a hog. Drop a nice trigger in, grab some pmags and your ready to go tho. I ran one in matches a few years ago and it worked extremely well for what it was and what they cost.
I think dry firing is an important way to train shooting on the move. when shooting live practice I like paper, that was I can run multiple drill without reset to see if hits and time improve
I had a harder time trusting and calling my shots on paper than I did steel for a long time for some reason, I have always liked shooting steel plates better.
