Im just starting off with both the ..300bo & suppressors. I built a 16" .300bo with a carbine length gas system 1:7 twist. Im planning on using my suppressor & cartridge combo to hunt deer/hog. My shots are always within 80 yards & being forced to track is bad ju-ju.. I'm looking to load a subsonic sledge hammer for ethical DRT shots.. I'm leaning towards the 220 grain family of projectiles. I can place my shots in the brain stem, if i can get a stabilized round that will hold 1 MOA. Not looking for a magic recipe, I'll tune my load as needed. Looking for a baseline to start, based on experience.
