looking for some advice. I shoot a savage axis II Heavy barrel 223 and I reload for it and most the times its a tack driver. 5 shots I can cover with a quarter at 100yards. now my issue is I can shoot reloads and it will shoot the 5 in a quarter and sometimes tighter. I got it to shoot the same holes 3 times with fmj reloads. I loaded the same loads again that gave me the tightest groups and couldn't reproduce the super tight groups again. soo... what do you rifle guys think the issue is? part of me says it needs to be clean, part of me says it needs to be a little dirty. I have waited 3-4 minutes between shots and shot, chambered and shot and the barrel gets a little warm so I pull the bolt and let it cool down. I shoot about 20-40rds and clean it. its driving me crazy I cant get it to shoot consistently.
