RE: Got a new gun!!!
Congrats on the rifle, and good luck with it.
I'm not a big fan of the boss system. It's sound in theory, however,I feel that it's not really that effective, and also it either needs to only be open or closed, not possibly in between. If you're hunting, and you want it open, your ammo is sighted in with it open, and a deer walks out at a range that will test your accuracy, but it's partially closed, your POI will be different. Additionally, I feel that the increased muzzle blast, sight and sound, makes the rifles feel like they kick much harder, and the little it actually reduces the kick is no comparison with the perceived recoil due to the increase in sound and sight. Sure, it won't bruise you as much, but it will scare you more, which will lead to flinching sooner than bruising would.
Screw the 10 ring, keep them in the zero!!!
