For plinking I like Winchester or Fed copper was bulk pack.
Mini Mags burn cleaner and generally have better accuracy, depending on your barrel.
I shoot a lot of Wolf MT for accuracy.
Bare lead bullets will build up gunk on the ramp quicker than copper wash in my findings. When you are shooting hundreds of rounds, it does make a difference.
Remington subs are so bad that I can gum up and AR .22 action in one mag.
Dirty rounds also contribute to the problem.
Something else to keep in mind with the CMMG's is 36 gr. HP generally runs better than 40 gr. solids.
