You need to use guns and barrels that don’t suck and aren’t picky about seating and pressure. I like to use stuff that works personally.
Over 15,000 rounds on this action and closing in on 8,000 on this factory 20” Tikka barrel. Never has a single patch ran through it. It still does this every time I shoot it for “groups” at 100 yards.
This was back when I switched from 73 ELDM to 77 TMK. New scope/rings, new stock, and a fresh brake clean wipe down and lightly oiled bolt. 2 sight in shots on the right and then 48 shot group to finish off the box of ammo on the left.
