Any variable I can remove from the reloading process , I do, & cleanin primer pockets is an easy 1 to do .
Seen accuracy issues solved with cleaning pockets & changing to mag primers in rifles(maybe not in that order) then not cleaning pockets & accuracy suffered. I will say this though , this particular rifle is capable of groups just a bit larger than bore size at 100yds & cost a good bit more than what I`d pay . 6MM Bench Rest was the caliber, forgot who made the barrel , on a Remington short action, custom stock (fiber glass) weighed 17 lb. 4oz. empty & no optics or mounts.
I feel it takes this kind of accuracy to see a difference in cleaning pockets or seeing a difference in brands of primers.
With that said , sure there`s deer rifles that are very accurate out there & shooters to go with em , but on the average shooters are after MOD (minute of deer) accuracy from an affordable rifle ,with not so premium ammo & then there`s handloaders that`ll tune the ammo to the rifle & achive MOA accuracy from a tuned rifle.
Any ways , I clean mine , all ways have , all ways will . Wish I could still see good enuff to shoot the difference !!
