Welcome back, Anthony!
You're best bet to get another frame is buy a complete rifle, then sell the barrel, but frames are available in the NEF Classifieds here as well as on some of the gun auction sites. You can also get the stock set on the complete rifle as well as in the Classifieds here and on Ebay also, or just order a new set from H&R.
GBO sponsor Gunstocks Inc offers some very nice replacement stocks if you care to finish it yourself.
www.gunstocksinc.comYour 270 barrel should shoot fine, they don't change the frame when they fit new barrels, changes are only done to the barrel, just as you may need to do to the barrel after you get another frame to put it on, see the barrel fitting info in the FAQs.
