Don't participate in competitive rifle shooting. However, spend a fair amount of time reloading and shooting for accuracy. Focus mostly on .223 through several rifles or different designs. Yes, AR 15 with quality barrels, one factory varmint gun. Shoot Remington 700's. One with PACNOR barrel and other Remington 700 VLS. Wondering if investment would increase accuracy or? Should I spend the dollars on bullets and powder?
