Hello All,
Have on order a Rock River 9mm Upper, for my AR-15. What size cast bullets are you guys using in them? I can't get an answer from RR on the groove dia of there BBL's.
I have a bunch of 147 grain TC that I use in my Cowboy Rifles sized .357 would like to use them or resize them if need be.
Thanks to all that respond.
