My buddy has been messing with the .358 Yeti, shortened .308 Win brass to feed an AR-15. Bullets have been a little tough to find 180gr HC and 200 gr FTX so far have been the most accurate for him. He's getting mid 2300 fps with the FTX.
I'm still playing with the .300 BO, if I wasn't shooting suppressed, I'd probably make it a .300 Hamr. So far I've killed 2 Oklahoma whitetails, one with a Ruger American Ranch rifle and the other a 7.5" AR pistol. Both worked very well with supersonic bullets inside 100 yards with a 130 grain TTSX and 125 grain SMK. This year I'll try some 190 grain Sub-X bullets as I have a few loaded up to try. I'd like to try some Lehigh or Maker expanding subsonic bullets as well.
