I'm looking at the Trijicon TA-11 series ACOGs (3.5 power)and I'm trying to determine which BDC will cover 6.8 SPC best .308 or 5.56. The load is the SSA 85gr Barnes tactical load and 110gr. OTM in tactical load also
Thanks

It really depends on which loads you shoot, A slow 115gr Rem or Hornady load will shoot completely different than a fast 100gr Nosler "Tactical" load from SSA, handloads can be much faster(200fps). Give me an idea of what you plan to shoot and I'll try to compare trajectories.

primarily the 85gr Barnes loads (TL) out of my 16 inch barrels there running aprox 3050-3100 fps, I just answered my own question, 5.56 BDC
