    Really slick idea. I was wondering about the rule book though. "No magazine, clip or similar device shall be allowed".

    Keith,
    I think I understand you at this point. If there is stable, repeatable vertical impact over a range of MV that is less dispersed than the mathematical value predicted due to drag, there must...

    Also of note, I was shooting 215 Bergers with a BC of .696 from 2700 to 2900 at 100 yards with up to 30fps spreads. Comparing this to your above example of .040 at 100 I would say I am not seeing...

    I welded and threaded a 541T before. It was a lot of unnecessary work in hind sight. I'd leave the holes. Just a thought on the pitch - a 3/4-16 is a common thread so if for some reason you needed...
