I looked at a older Savage 110 today at local shop
it was a .308 heavey barrel with a recessed target crown
the barrel was little or no taper - and marked Savage 110 S serries J
it had a very unique wood stock as well - walnut with a palmswell -
& palmswell was textured up to underside of forearm

from the frequently asked questions sections I found this

The 1st Generation short actions are often incorrectly referred to as "Series J" actions or Intermediate Actions. These actions will have a three digit model number (110, 112, etc), but are approximately 0.540" shorter than the standard long action.
a rifle can be marked with a series letter other than "J" and still be one of these 1st Gen short actions

but does any one have any thing more to add .....about this bull barreled .308?
never seen a heavy barreled rifle that old - looks like it would shoot bugholes
half tempted to buy it -
but Im kinda leaning towards a newer roundback action
any info appreciated
