[QUOTE="kraky2, post: 99225, member: 3532"] The can also says START 6% LOWER. But all that aside I'm gonna try and copy over the data they show at Hogdons' website for 180 grainers. Goodness the start load is running 58,000psi and the max is only 4,000 higher for all that difference in powder. I've never seen that many grains make so little difference. I'm beginning to wish I hadn't volunteered to load my buddies gun....it looks like a project I should be doing and watching closely myself. 180 GR. SPR SPBT(Starting Loads) DIA. .308" COL: 3.530" H50BMG 103.0 3005 53,700 PSI H870 103.0 3130 54,000 PSI RETUMBO 94.0 3182 58,400 PSI H1000 91.0 3018 52,300 PSI H4831 84.0 2997 54,000 PSI 180 GR. SPR SPBT(Maximum Loads) DIA. .308" COL: 3.530" H50BMG 108.0C 3159 62,100 PSI H870 106.0 3206 58,200 PSI RETUMBO 100.5C 3300 62,400 PSI H1000 96.0 3218 62,800 PSI H4831 89.0 3167 62,500 P [/QUOTE]
