Have a Wilson AR9. Use glock 33rd mags. Does not like bullets longer than 1.140". Using 5gr N340, Berry's 115 gr hollow base, CCI primers, and range brass. Not a single problem since I started reloading.
Shot Steal Challenge over weekend, 200 rounds no problem.
Like NervousEnergy's comment above;
"I just need to figure out how to get faster. In a way it would be better if it jammed more often... I could blame my mid-pack showings on the gun. Unfortunately it's all on me... sacrificing too much speed for accuracy, and that loses stages time after time."
Have a good day and a better tomorrow.
