I have 3 rifles in 300 BO. Just Tuesday we were plinking steel at 400 and 500 yards with my 115 Berger ammo. Body shots were easy on full size silhouettes that far, so we started taking only head shots at 400 and 500. 3.5 mils to 400 and 5.4 mils to 500 yards from a 100 yard zero. When we missed, it was due to wind off the right edge, in some switching winds from the 4 o'clock to the 6 o'clock (.3 to .8 mil wind hold). This was with my Rem 700 AAC 16" with Shark can. When mounting my new Vortex 2-10 mil/mil scope, I was getting one small cluster of shots on a 3/4" shoot n see dot. I love shooting my 300 BO's. It is a very fun caliber with low recoil. I run the 115 Berger mainly in my bolt guns, and hunt with the 125 grain bullets on my AR with thermal scope. I have taken several deer with this round, several pigs, a few coyotes, and lots of small critters when deer/pig hunting was slow. Everything was DRT, except one pig that ran about 40 yards, and 1 deer that ran about 10 feet. Everything else dropped on the spot. IMO, it is a near perfect caliber for Texas hunting out to 150 or so yards. I have taken a step back and kept my hunting calibers very simple. I no longer want the big calibers for basic hunting at normal distances. Give me just enough power to be effective without over kill, and the 300 BO is it.
