I recently purchased the Brno 21H chambered in the 7x57. I purchased a set of Warne Quick Detachable High rings and placed a Leupold VX2-4x12x40AO on it. I was going to start off with 140 gr. accubonds then changed my mind to 160 gr. accubonds. I conducted load development with the 160's using IMR-4350 and Reloder 22. This rifle has a very long throat, from the case head to the ogive is 2.786". I seated the bullet .064" shorter than the ogive length so that it can fit into the magazine, with room to spare. The COL is 3.304". It will be about 10 days before I can get to the rifle range to test her out. It's a lovely slender stalking rifle.
Makes my other rifle feel like a unwieldy bloody 2x4!
I’ve used 140gr accubombs in other 7x57’s loaded with H414 before but never with my 21h,
Let us know how it went at the range
