OK this is a retarded question I know, but here goes. Is there anyway to tell which barrel shank I have without removing the barrel? My first guess was to call Savage, and ask, but since the rifle was manufactured before Nov. 1995 they can't tell me anything. If it matters its a Model 112, LA, I bought it new around '93-94.
 
Measure the barrel right where it exits the nut. 1.2" is large shank, 1.055" is small shank.

Large shanks were only on WSM and RUM's prior to the precision target actions.

Standard shank nuts are 7/8" (0.875") in length, whereas large shank nuts are 5/8" (0.625") in length.
