I have a cheapo savage mark 2 22lr non accu trigger standard barrel I got a good deal on and could never get the dang thing to shoot worth a crap so I changed scopes and same thing so this week I decided to put a better quality bushnell 3-9 on it and see what it would do. The barrel was filthy from popping pop cans but ive always heard don't clean a 22lr. Well I cleaned mine really good the other day and set out to shoot today at 50yards with agluilla, federal auto match and Remington thunderbolts. Every shot I fired was spread like buckshot. I'm talking like 2-3'' groups and I almost said screw it and went home until I decided to fire another federal auto match group and they started tightening up and then I switched to aguilla yellow box and man I could stack 5rds in a quarter at 50yards.
Mind you, this gun is non accu trigger and has like a 6lbs trigger and its wearing a centerfire scope so parallax might be off a bit. I moved to 25yards to see how zero would change cause its a squirrel/coon gun and they now all touched with aguilla. IDK how moving closer shrunk the groups but ill take it.
After firing about 30rds every group with thunderbolts, federal and aguilla held minute of squirrel head at 50yards. I guess it is true that 22's need to be dirty and we should never clean them!
