What power is your Ranger ?? 35-50 or 80fpe

I've not shot the Range Masters but my 40fpe AirWolf loves the 21 gr Kodiaks and also the 15.9 JSB's @ 100.

I have managed 14 sub MOA groups @ 100 and and 1 sub 1/2 MOA @100. in total with my guns over the last few years.

80% of my shooting is strictly benchrested long range shooting, the other 20% is at 50 and 75 on windy days....
