Need some ammo ideas to test the potential of my new AR. It's a Eagle Arms M15, 223-5.56, 1 in 8 twist, and 16 inch barrel, something in the 50 to 55 grain range. there's so many different brands and weights a starting point would be very helpful. I know no two rifles are the same but there should a good starting point. This will be mostly used for varmints. Thanks
