    Any benefits of a heavy buffer in an Aero Precision 308 with A2 stock?

    I built it with Criterion heavy 20" barrel and adj gas block for NRA LR Service Rifle. I noticed that when the gas adjustment is set for reliable operation ( Odin works, 7-8 "clicks" open) I'm showing a forward ejection pattern and slight ejector swipes. With the gas system closed, no signs of...

    How accurate are Electronic target's terminal velocity readings?

    ShotMarker or SilverMountain/SOLO are pretty common now in NRA F-class matches and gives us those readings at distance, just curious if they are "correct"? They seem pretty consistent from one mfr to another.

    AR 308 barrel twist rate

    Looking at 20" .308 Criterion barrels for a 308 AR build, 1-10 or 1-11. I normally use 175's for all my loads when shooting NRA midrange and long-range (800-1K). Tech at Criterion says either will work fine. My F-T/R rifle is 1-10 and the LRB M14 is 1-11 and both do the 175's fine. Just looking...

    **Update** How much chromatic aberration is accceptable in a Steiner T5Xi?

    I recently picked up a Steiner T5Xi 5-25 (used) and was surprised by the amount of CA in the 10x thru 25x range. I have no complaints about clarity or detail at distances 800 thru 1100yds, really good resolution actually. For years I have used and still own several Leupold Mk 4's such as the...
