I'm thinking about it now! I've got a suppressed 7.62x39 upper that shoots full power ammo great, but the EBR 220grn subsonics are all over the place. I've kicking the 300 whisper rebarrel idea around for a year or so. Now I've read this post and researched the round and think this might be a better rout to take.
There's a boy on Snipershide that has a Noveske 300blk upper for sale and I'm seriously thinking about it.
At the moment, I don't reload...which is why the 300 whisper hasn't come home. But now, it may just be time to start gearing up.
My good lady is going to take a stick to the both of us

Damn black rifle disease.
Cheers,
