The Green Mountain fast twist 50 cal Stainless barrel was waiting for me this afternoon when i got home from school. I really felt I needed this barrel to replace a 54 cal 1/48 twist barrel on my oldRenegade, but being the old baseball coach that I am - I decided a double switch was in order. I put the new stainless ina 50 newer Hawkin that I had - moved the good Hawkin barrel 1/48 to the renegade. Both barrelsonly took a minor amount of inletting and they were in. Even though the old Renie barrel is1" barrel - the 15/16ths Hawken went in without a problem (ony a smal bit of inlettingto get the under rib in the stock. At a later date I will probably add a little fiberglass bedding under neath the barrel. Nowit needs to be nice this weekend or at least semi nice so I can get out and shoot this new stanless.
