[QUOTE="nbowlin, post: 1702431, member: 39335"] I have a 16” .458 socom. I have a thing on the end to help with noise. I ordered some 400gr sbr subsonic and it’s supersonic. I ordered some black butterfly 500gr subsonic and it’s supersonic. I ordered dies and bought some cheap Speer 400gr spfl stuff for the sake of science. Started at 11.5gr of unique and large pistol primers. Went backwards to 10.7 and got that air compressor nozzle being depressed noise I was looking for. Loaded some more to work on getting the thing to cycle. Well the first 3 were air compressor sounding. I am cutting down the buffer spring between firings. Then there for after back to super sonic. I went all the way down to 9.5 from 10.7 and never got back to sub sonic. Nor does it cycle but that’s another aggravation. How can this be a thing? [/QUOTE]
