Heading to the range this weekend and gonna take the mini 14. It's a 182 series with a barrel length cut to 16 inches. I have a stock of 55gr ammo (shared with a Bushy AR). Being that the barrel is a 1 in 10 twist, and cut down, I was considering getting lighter rounds like 40 gr or 50 gr. I'm looking for accuracy to 100yds max. Not using a scope, just a FastFire red dot. Should I even bother going lighter or run what I have? Will there be a noticeable difference? So far I've had no issues with the 55gr ammo. I am able to Skeet clays on the bank at 100yd.... plenty accurate for me. Just looking for a few thoughts.
