I was wondering if anyone had any experience with EGW bases. I am building a 6mm BR for informal shooting matches and varmint hunting. They offer bases in 15MOA and 25MOA. I was told that I would need 20 MOA to get me out to 600 yards. I was wondering if the 15MOA would get me there and still have usable adjustment for work at 100 yards. I know the internal adjustment of the scope will be the determining factor of available range. I have benn looking at the new Sightron 8-32x56, but also thinking about the Bushnell elite 8-32x40. Any input will be appreciated.
