Did a search on NE and found this thread, which appears to be a 7x66 SEVH - http://forums.nitroexpress.com/showflat.php?Cat=0&Number=73139&an=&page=0&vc=1 I see the 7x66 ballistics are about 3000 fps for a 170 gr projectile. The 7x73 (belted) cartridge generated a "reported" 3300 fps for a 170 gr projectile - per factory Gehrmann loads, which COTW reports as "optimistic". |
