Glenns in reading "might" have it. Being so close to reading rifle that shoot this sort of ammo.... I dont know many people though not reloading 223/5.56 for shooting matches.
Depending on how much you shoot a year and what you are shooting out of depends on your reloading investment.... current cost for me useing nosler custom comp bullets
primer .035 cents , powder .08 cents , bullet .17 cents..... brass at this point is free
total 28.5 cents each
