[QUOTE="AZHTR, post: 2085760, member: 105904"] I’ve read many “opinions and articles” on neck tension, however, I have one question I’m needing some of your expert opinions on. My brother and I shoot “almost identical rifles”....7mm Rem Mag, Nosler brass, CCI Primer, 168 VLD Berger’s, 70.5 grains of IMR7977, .025 OTL. (26” Bartlein barrel, same reamer used on both) His rifle shoot ~3040 FPS and mine shoots ~2925 FPS. (And I do understand ALL barrels Have their own idiosyncrasies) The only process that we don’t do the same is neck sizing. He uses a bushing type and I use a .283 mandrel. (I have shot his reloads in my rifle and experienced the higher FPS) Ok, here comes the question - can that difference in reloading NECK TENSION be a very consistent difference in a 100+ FPS? Please let me know what your thinking, thx👍🏻 [/QUOTE]
