I've seen a couple of posts recently about primer fit and blowback, and got to wondering if I'm the only guy that adjusts the breechplug for a tight seal.

I use teflon tape on my plug, and screw the plug in against the stop. Then I put a primer in and close the action. If it closes easily, I open the action and back the plug out 1/8 turn, then close it again. I keep doing that until it will no longer close. Then I turn the plug in 1/8 turn so the action closes tightly against the primer. The tight fit really reduces blowback.

Does anyone else do this?
