AR-50 50BMG target rifle. NightForce 12-42X56 Competition or 8-32X56 NXS as needed. These scopes replaced my 2 Leupold Mark 4 8.5-25X50 LRT scopes which are used on other builds now.
Main competitions are at 1000 yards - on a good day I shoot 4" 5-shot groups - normal days I shoot 8" groups - ALL groups are 5-shot groups.
I have shot my AR-50 out to 2 miles but do not attend those competitions due to physical limitations.
I'm currently shooting PECA-16 Swiss brass annealed with an AMP, CCI#35 or Genix primers (CCI#35 must be "Armed"), RL-50 or VV 20N29 powder, Lehigh 808 brass solid projectile.
Using a K&P 38" SS 416R barrel with a Match 0.554" chamber with custom throat to achieve 3000 fps with match loadings.
I shoot more 50BMG rounds than 223/5.56X45 which is embarrassing at times. I used to own 7 different AR-15 style rifles = down to 2 specialized AR-15's now, 1 in 223Wilde chambering 20" chrome-lined, other in 6mmX45 target Shilen SS bull barrel, both scoped appropriately (scopes cost 4X rifle build cost).
