[QUOTE="Horse1, post: 2168494, member: 112817"] I had my 257Wby assembled in '08. 'Win M70 SS Classic, #3 Lilja @ 25" 1:10 3-groove, McMillan Classic Edge fill. 22 and Ramshot Magnum were the only 2 powders I tried. Magnum was a bit faster but significantly lower ES/SD and demonstrably more accurate than '22 for me. I run the Magnum through a Harrell's Culver dispenser to +/- .1gn. Assuming prepped brass, I could run them on a Dillon 550 the powder meters that well. I haven't actually chrono'd Magnum in really cold temps, but, I've taken a cow elk and at least 1 Mule Deer @ 0F ambient with zero drama. [/QUOTE]
