[QUOTE="lancetkenyon, post: 3006384, member: 68875"] 28 Nosler. Almost the king of 7mms. Depending on how hot you run them (195 @ 3150+ is not out of the question), expect accurate barrel life to be between 400-1000 rounds. 3030-3080 is a sweet spot with the 195s. Barrel life should be in the 700-900 range at these speeds. As for the Sherman lines (based on 24-26" barrels). 7SST (shortened SAUM case). 180 class bullets 2800-2900 is realistic. 7SS (shortened SAUM case, improved 40°). 180 class bullets 2850-2950+ is realistic. 7Max (SAUM improved 40°). 180 class bullets 2900-3000+ is realistic. 7MEGA (WSM type improved 40° with long neck). 180 class 3000-3100+, or 195s 2875-3000ish realistically. I have a 24" 7SS pushing a 184 Hyb @ 2840 w. H1000, or 2920 w. RL26. I have a 26" 7RM pushing a 180 @ 2996 w. H1000, or 184 @ 3035 w. RL26 I have a 26" 28 Nos pushing a 195 @ 3084 with a moderate load. Measure the mag length of the Win 70. That will help determine your choice. I am not sure how well a 28 Nosler w. A 195 will fit. Same with a 7-.300WM. COAL will probably be an issue, since the WM case is longer than the Nos case to start. I would look at the Max , Mega, or PRC personally. [/QUOTE]
