Hello all Ive got a jynx that I cant figure out whats up Ive got a savage 110 LA that was originally a 30-06 and a couple years back I picked up an adams and bennett 338-06 barrel and the barrel nut wrench and we put the 338-06 barrel in this rifle and it worked swell with no troubles at all and I just picked up a 284 winchester barrel for the savage 110 and when I get the head space set and lock the nut down the firing pin wont strike the primer and it wont extract the case from the chamber and Ill be doggonned if I can figure out whats goin on here and thought I better turn it over to some more knowledgeable than I.
