So I had a Brunton 3.5-10x50mm just laying about the house, and I decided to put it on my AR build. I zeroed it at 25yds real quick with some random 55gr fmj. After that I walked it out to 100yds. .45gr JHP Winchester Aiming at the middle of the Hazard symbol. Just under an inch. Needless to say I'm pretty happy! I'm gonna reload some heavier stuff to see what this 1:7twist can really do.
