Would like options on my first attempt at an OCW using Varget in my RRA AR 20" Predator Pursuit, 1:8, RRA 2 stage match trigger, Millet 4.5-16 scope, bags front and rear, using 69gr SMK, OAL 2.260. All the brass was once fired PMC in my AR, except somehow I let 6 brass of other headstamp get into the mix. I dont think they skewed the results too badly though.
I fired two fouling shots first, using my normal load of 22.5 gr H335, same bullet, same OAL. I used the OnTarget Precision Calculator to determine the spread of each group. After shooting all the OCW test rounds, I fired two more fouling shots (I had them left over) of my normal H335. These 4 rounds had a spread of .809" (three almost in same hole).
For the OCW, 3 rounds each weight, round robbin, all rounds at 100 yds, temp 35*, no wind.
Looks to me like 25.1gr Varget is the OCW.
gr / Spread
23.3 / .751"
23.5 / .518"
23.7 / .604"
23.9 / 1.724"
24.1 / 1.272"
24.3 / 1.613"
24.7 / .823"
24.9 / .816"
25.1 / .508" (.485 MOA) <<<<
25.3 / .792"
25.5 / .679"
25.7 / .608"
25.9 / .695"
26.1 / .692"
Next, I plan on seeing how my current load of H335 compares against the Varget. (I really dont care for the Varget, as it goes through my powder drop like dirt!!)
