i read Zaks cleaning thread a few times and decided I didn't care about cleaning. Recently though I've had a new barrel, new brass (alpha), and needed to do some load testing. I run 6.5 creed in an AXMC 26" and an ultra338 can. I broke barrel in with 300 rounds. I've struggled getting this brass to shoot half inch or better. I figured it was the brass until today. I took the can off and my groups were easily .25 to .5 immediately. While shooting with the suppressor is get .5-1.2 which is unacceptable. I have about 2k rounds on this suppressor and cleaning it now but my question, has this been experienced by anyone else? Curious if cleaning would fix this or if it's something else.
