I know there is probably still a hard core group that's still in love with the 300BO but it seems that the love affair is over and you don't hear about it as much anymore. I was and still am a fan of it's grand daddy the 300 Whisper as originally introduced by JD Jones waaaaaay back in the dark ages for the Thompson Center Contender but never got one in an AR nor did I consider it a serious medium to big game cartridge.
My new love affair is with the 6.5 Grendel for everything from 1000yd targets to prairie dogs to hogs and whitetail and I've heard it suppresses very well but I haven't gone that route yet.
What do y'all think? Has the Grendel eclipsed the Blackout?
It seems to have so many more capabilities and it seems to be so much more versatile.
I hope this doesn't start a ****ing match but rather a good discussion of the good, the bad and the ugly of each cartridge.
