[QUOTE="LouBoyd, post: 287610, member: 9253"] For the data you've given and going only by Quickload I'd choose N560 for the 175 SMK seated at 3.090" OAL 64.5 grains gives 2881 fps, a load 15% under SAAMI max and a 91.8% case fill. 68.0 grains gives 3038 fps whch is at the SAAMI max pressure and a 96.7% case fill. If it was my rifle I'd probably run it at whatever load in between those groups best. I usually try for 90-95% SAAMI loads and 95% case fill. N560 gives highest muzzle velocity of the powders on your list with comfortable case fills. Reloader 25 is second choice. I like the of the VV 500 series powders. They frequently calculate to give the best performance. [/QUOTE]
