Anyone else have a problem with a M&P 9mm stock barrel. I am using the 147rn and they wouldn't fully chamber AOL was 1.130. I purchase a storm lake barrel and haven't been having the issue figuring the chamber on the stock barrel is a tighter tolerance were the heads are .556. Been loading these with 3.1 with TG and accuracy has been dead on with a PF 132.
