Not totally true. Some of the target actions had a 3.40 spacing but the majority of them were and are 4.40 for screw spacing. The difference is all target actions are large shank barrel threading, and triggers that will adjust down to around 6oz..
Only some of the magnum model 10's 11 12 and so forth have large shanks but none go below 1.5 lbs. for the triggers
The differences are basically aesthetic but the measurements including the screw spacing on short actions are the same.
