Series J

[bootsmcguire]

You will hear the term J series used often describing actions, The long action rifles with barrels marked J Series are just standard 110 or 112 Long actions with Staggerfeed magazines. The Short actions with barrels marked J series may be equipped with the "Intermediate" Short action which has a screw spacing of 4.52". Savage's next version was their first true short action which has a screw spacing of 4.27" and were equipped with SF magazines, and then the next were the 4.40" spaced actions equipped with Centerfeed magazines.

So the best way to tell your action is to measure the screws, center to center, but if you see someone referring to a "J Series" action they are talking about the 4.52" spaced Intermediate Action.

Also FYI all long actions have a 5.062" spacing and can have either a SF or CF magazine. The mag cut-out in the bottom of the actions are different for each mag style.
