I have a high end AR-15 I put together last year. Proof Research CF 16" 1/8 barrel running a NF ATACR 4x16 in a badger C1 mount. Benched with Bipod and rear bag.
I have it zeroed for BHBB 223 75g MHP. I decided to get some Federal Gold Match Premium 77g SMKHP and upon firing 3 rounds, at 100 yards, I didn't even hit my paper target. Hum. I found out that the Federal was shooting about 3"- 3.5" inches high at 100 yards. (I didn't measure the exact distance at the range)
I really didn't think there would be that much POI difference going between the two. I'm curious to see if that is normal or not.
