After zeroing and working out my dope to 600 yds I had 7 bullets left so I thought I would see what I could do at 100 yards with the remaining 7 shots.
My best 6BR load is 30.3 grains of Varget, Berger 105VLD's just touching, Lapua brass and CCI450's. My reamer has .104" free bore and a .269" neck. This is a tight neck and loaded ammo runs .268" at the neck but, a tight neck has no real advantage to a no turn when the bullets are touching or are in the lands. I've found the small base FL bushing die gives the best results with this cartridge.
Nice rifle, looks to be a shooter as well..............big surprise seeing it's a 6BR
My 6 BR is a Prone Gun with iron sights and is a hammer. I am looking forward to the next one. After seeing yours I expect I will follow your lead. Does your 6 BR feed from the Magazine satisfactory.
