Pulled the brake on my Grendel earlier for cleaning and found a lot of carbon build up on the crown. Its thick and has a very uneven surface. I noticed that before the last match i was going to shoot, it no longer grouped at all at 100yds. Over the last two to three hundred rounds ive noticed it open up and no longer an MOA rifle. Can this build up affect grouping for zero check? Thanks for any info. [ATTACH=CONFIG]14707[/ATTACH]
