Some more testing with RE17 powder. I used it in 2.75", 3", 3.5" 12ga plastic, 3.5 and 3.85" brass. I like it the best of all, as well as the real slow powders in our long case with BMG primer. Following tested in Savage-max pressure 35k psi. I took couple of our first made 3.85" BMG based long cases and bushed them back to use shotgun primers to fire off the RE17. Works great, with 715gr jacketed slug and 220 gr RE17 getting 2700 . With 420 gr slug in BPI sabot with 250 gr RE17 getting 3200 plus. Following tested in NEF-max pressure 25k psi. Using 3.5" MRC brass, 715gr jkt and 200gr RE17, got 2500. 420 gr in BPI sabot and 220 gr Re17, got 2900 fps. And we get real good velocities in plastic with half the basecup expansion of factory mag loads.So that solves problem-IE, being able to use regular firing mechanisms and shotgun primers, with large enough powder charges to get hairy velocities at mag shotgun pressures in plastic and higher in brass cases with heavy barrels.A good powder for plastic and brass loads.
We are being copied and heavy barreled NEFs, deepen chambers, and get 3.5" brass now from RMC. Also harrier loads as I see now that Lightfield Co has the Commander 3.5" Plus slug loads with 600gr at 1900, probably in a test barrel. But that is great- nice, as it seems we're being copied!!!ED
