???How often should this be done?I shoot Triple7 in my Omega and dont shoot more than 70grs..I also use small pistol primers in Variflames and lately have noticed an increase in breech fouling and a drop in accuracy and consistency.This plug has about 600 shots through it.T/C doesn't have recommendations regarding new plugs so I'm curious, How often should you swap plugs and what is the largest the flame aperture should be? Thanks.
