Rephrased; what was the "coldest temp" you either (a) killed game with your load and/or (b) you tested it for speed/accuracy?
Not from a 7x57 but two years ago I killed a cow elk with a 30-06 using W760 powder. Load was worked up at roughly 100* here in Tucson and the elk was killed in New Mexico as 6* above zero. It was maybe 10* at the Whittington Range at Raton when I checked zero prior yo the hunt and point of impact was unchanged. I've done several hunt on the same ranch in NM using a .35 Whelen with Re15 powder, and a .270 and .300 Win, Mag. that using WMR powder (long discontinued) when tested at the range showed no change of impact. The whelen was used in the taking of five elk. The .270 and .300 Mag. were back up rifles. Paul B.
