[QUOTE="B23, post: 1503349, member: 13222"] Defensive Edge built my 7mm Blaser using a Hart fluted #4 finished at 26in. Mine isn't throated super long, my OAL w/180 Berger is 3.260 which is 5 thou off, so I'm probably giving up a little velocity but Shawn did his +P throat on mine so it's probably a wash. With the +P throat my load is 68.5gr RL26 and that's getting me 3088-3100 and shoots in the .3's. Mine will run well over 3100 and it even still shoots well at those speeds but I start getting clickers and little shiny ejector mark too. The only commercially available dies that are available, at least that I could find, were the standard Redding dies and Norma makes the brass. I wouldn't mind having having a bushing die though. I think in a medium weight rifle using a 26in barrel these 7mm Blaser mags hold their own and run right with the much larger case capacity cartridges like the 28 Nosler, 7 STW, 7-300Wby, etc. I'm sure if you compare the 7mm Blaser to those others and use a 28-30 inch barrel they'll show their extra horsepower but they're burning 15gr more powder too. I've been gravitating toward building rifles with a max barrel length of 26in. and that seems to be a sweet spot for these 7mm Blasers.[ATTACH=full]109421[/ATTACH] [/QUOTE]
