[QUOTE="montana_native, post: 268866, member: 12881"] I have obtained the following load data for my Edge. All with CCI 250's, 3.920" OAL, 0.010" off the lands, runout <0.003" and 300 SMK's [B]H-1000[/B] 92.0 gr, 2827, 2834, 2836 fps, AVG. 2832.3, 9 FPS spread, 0.354" 92.5 gr, 2850, 2850, 2866 fps, AVG. 2855.3, 16 FPS spread, 0.409" 93.0 gr, 2886, 2889, 2879 fps, AVG. 2884.7, 10 FPS spread, 0.367" [B]RETUMBO[/B] 94.0 gr, 2886, 2867, 2882 fps, AVG. 2878.3, 19 FPS spread, 0.388" 94.5 gr, 2900, 2907, 2894 fps, AVG. 2900.3, 13 FPS spread, 0.410" 95.0 gr, 2895, 2900, 2898 fps, AVG. 2897.7, 5 FPS spread, 0.329" None of the brass/primers show pressure signs. I find it strange how the Retumbo leveled off. What load would I be best off with? The small difference in group size is probably from me. They all seem to shoot about the same. Would there be a huge gain in brass life by going with the lighter loads? Ballistics calculators I have played with indicate very similar performance between them all. Thanks. [/QUOTE]
