I don't have a chrono and would appreciate your best guesses at velocities. I am trying to come up with some starting velocities to plug into a ballistic calculater. Here are the specs.

Armalite ar10
18" noveske -smith vorte
175 smk
CFO lr primers
loads
42.5 varget
43. Varget
44.0. Varget

rem 5r
stock rifle
same loads plus
155 amax moly
43.5 varget
44. Varget
44.5. Varget

fc cases trimmed per load manual

I realize that every rifle is different and conditions vary. I am just looking for a starting point.
