Who does not trim their brass?

You can buy the little caliber specific plugs to check your actual maximum brass length. Most of the "maximum brass length" SAAMI numbers are much shorter than what a chamber allows.

I think they may be made by Stoney Point, but I can't recall off the top of my head, sorry!

Fairly simple to check your chamber’s actual maximum brass length. Resize and trim a case extra short. Cut a slice off the mouth. Insert a bullet in the case. Add the slice to the bullet. Chamber the modified case/bullet. Seat the bullet deeper until you can close the bolt. This will show your maximum brass length for your chamber.

Wipeout and JB’s, and elbow grease.

That literally the barrel fresh from the gunsmith…….. before shot 1

I only started using JB recently to clean up a real wreck of a milsurp bore, used the Red, and it works like a charm. Wish I got into it sooner.
The old school carbon/copper removal layer after layer forever is pointless now.
It gets it all out in 1 go.
