I am getting lazy. Help to get me shooting this great cartridge.
#1
I am starting a tentative drop chart on the hornady 123gr amax load in a 19.5" alex arms upper.I am wondering if anyone would share prelim drops with 100 yd zero for 50,100, 150,200, 250, etc. Just to get me started? I am behind due to recent trade and really amscrambling to get it ready for the season. Many thanks in advance. Mingokid

Need to know your muzzle velocity, density altitude, scope height above bore, and what output unit your scope knobs use...MOA, MILS. Use Brian Litz's ballistic calculator from Berger's website, or other ballistic programs. Here's just a preliminary idea based on sea level, 2550fps mv, 2.7" scope height, and Mils.

Code:
.......Range Velocity Energy Trajectory TOF Drift (yards) (fps) (ft-lb) (MILS) (sec) (MILS) 0 2550 1776 0.00 0.0000 0.00 50 2463 1657 -0.35 0.0598 -0.10 100 2378 1545 0.00 0.1218 -0.21 150 2295 1438 -0.17 0.1860 -0.31 200 2213 1338 -0.48 0.2526 -0.42 250 2133 1243 -0.86 0.3216 -0.54 300 2055 1153 -1.30 0.3932 -0.66 350 1978 1069 -1.77 0.4676 -0.78 400 1903 989 -2.28 0.5449 -0.91 450 1830 915 -2.82 0.6253 -1.04 500 1759 845 -3.40 0.7089 -1.18

Many thanks. I will make my measurements and chronograph the loads in my upper. I haven't been this excited about a new "stick" in a while. MK
