Re: Retumbo temperature expectations
A few weeks ago I had the opportuinity to fire a few rounds at coyotes when it was single digits F in the early AM. My dope did not change by any amount I could recognize, much less measure. The Retumbo, Fed215M, BergerVLD load was developed in 60 -70F weather. Took 2 coyotes with a 7RM on consecutive mornings. First yote was a 325y., broadside and the second was 665y head on, sitting. Neither one complained.
I don't get to shoot this rifle often and this was an opportuinity to shoot at a possible longer range in the cold. Now I know my cartridge load/dope table is good with a cold bore shot for the ranges I would be hunting.
