I like the BOSS System it works very well if you take the time to tune it, and you should always wear ear protection anyway. I have a friend that has the BOSS System on a Browning A-Bolt Medallion 300 Win. Mag, and is obtaining under .50" at 100 yds. with factory ammo. Are you sure the barrel will be only 23" with the Boss System? My Browning 2001 - 2002 Catalog dosen' t say either way. That means your barrel will be about 21.5" . Your going to be giving up some velocity. I would ask Browning just to make sure. If it is the case, I would go with the 300 Win. Mag. you will land up with at least a 24.5" barrel. Good luck.
