Bump a little more. If you are already chambering tight, things will likely get worse. Fouling, dust and heat can make things get sticky after several hours and dozens of rounds on the prairie.Another question: the 22-250 is set up on about a 1 thou shoulder bump, but the bolt is snug on closing. The thing shoots amazingly well for what it is, so I’ve never fooled with it. Will that be a problem After a few dozen rounds at varmints? Any reason to be concerned about the chamber getting a bit fouled and not being able to close the bolt? I can adjust the die to bump a hair more.
