[QUOTE="wildcat455, post: 1614052, member: 102653"] Lance, are you measuring your BTS (Base To Shoulder) with the spent primer in? I only ask because in 4 of my 300 Win Mags I seldom get over a 2.270” measurement without the primer. Usually 2.268”- 2.271”. With the primer, the crater throws my measurements off to about what you show. Just curious. OP, This is what I have for case data so far on the 300 Win Mag. NOTES FOR CASE DATA 300 WIN Below dimensions and weights are from FIRE FORMED CASES in my rifles. Legend: W= Weight L = Length S = Shoulder N = Neck C = Capacity filled flush with H1000 T = Thickness at neck FWV= Filled Water Volume gr=grains BARNES W 221.0-222.6 gr FWV 95.3 NORMA W 222-224 FWV 95.5 PPU CASE W 240 gr L 2.608” S 2.270” N .333” C 90 gr T .014” FWV 93.5 Case weights and volumes vary allot WINCHESTER CASE W 242 gr L 2.608” S 2.268” N .333” C 90.1 gr T .014” FWV 92.2-93.7 Case weights and volumes vary allot. HORNADY CASE W 243 L 2.606” S 2.269” N .333” C 90.0 gr T .014”-.015” FWV = Didnt measure. Stopped using these cases before data could be obtained. OLD FEDERAL CASE W 250 gr L 2.610” S 2.268” N .333” C 89.0 gr T .016” FWV 92 gr NEW FEDERAL CASE W 252.5 gr L 2.610” S 2.268” N .333” C 89.0 gr T .016” FWV 91.3 ADG CASE W 254.6 gr L 2.216” S 2.269” N .332” C 89 gr T .015” FWV 92 SIG SAUER W 254.5-259.3 gr FWV 91.3 Stopped using these cases before full data could be obtained.
