My AR-15 has a 1:7 twist and I have several cases of 55 gr. USA ammo. My initial (and pretty much only) experience with accuracy was horrible when shooting this rifle to qualify for a CMP M-1 Garand. I'm not at all sure it is sighted in correctly. My question is...is 55 gr. ammo suitable for a 1:7 twist? Or do I have a lot of ammo that is a mistake? Sorry if this topic has been beaten into the ground previously. Thanks.
