well i got my 357 mag barrel back from being fitted at nef.took it and my .380 carbide chucking reamer too my buddies (he is a gunsmith).it didnt need alot of reaming since the factory barrel is really long throated.the .380 chucking reamer worked great and now i can shoot 357 max .took it too the range and it shot great,even with 38's,now i have too work up a good load for the 357max for the rifle and my blackhawk pistol.let my buddies 12yo boy really break it in for me(lol),he had a ball.he is already wanting too use it next deer season,by then i should have a good load all worked out for it.i think i am addicted,what caliber is next? take care don
