Quote from: graydigger525 on April 16, 2017, 06:37:56 PMCAUTION RL16 !!!!!!!!!!!!!!Hey y'all just want to put out a yellow flag if you are starting to play with RL16... did some initial testing of RL16 and RL 26 today. (Berger 140 VLD-H out of twice fired, sized, turned and annealed Nosler brass (158 gr) , pockets uniformed, Fed 210 M, BTO 2.182, COAL 2.844 (0.025" jump this gun), neck wall 0.0130", 0.285" bushing, loaded neck dia 0.289", loads trickled with calibrated GemPro; this gun Defiance Deviant Tactical w/small pin, 24" Benchmark on a Manners overbedded mini chassis w/Jewel, barrel fully sweetened.)Primers cratering at 42.6 gr RL16 2908 fps (LabRadar 56F). Progressive development of pressure signs: 42.9 (mean 2934 fps), primers flattening with slight E marks, blown primer at 43.2 (2945 fps), very heavy bolt lift 43.5 (2963 fps). I can't believe the suggested higher end load data posted for the SMK pill. (My control load shot today was my pet load of 42.0 H4350 (everything else the same) making 2815 fps, sd 8, 0.38 moa 300 yds, which is kinda where it usually is given temperature.)I dont know if others have tried, just wanted to get this out - PLEASE EVERYONE BE CAREFUL!!!Interestingly, RL 26 was strikingly benign with absolutely no pressure signs from 46.5 gr. up to a slightly compressed load at 48.1 gr (making stupid 2965 fps). I remain intrigued by both powders as a possible temperature stable alternate to H4350. We'll see on precision, but < 42.5 gr. RL16 appears promising.
