kevin.303: good on ya. Yeah, they are bigguns, aren't they.
OK, if you look at your stock disc there should be an arrow or traingle with the apex pointing to a number. That number indicates the degree of barrel degradation, as I understand it. Maybe BigBill can give us a more accurate answer but I think I'm close to being right. The numbers range from 1-3 with 3 being the worst and will still group within an inch at 100 yds. Mine is a #3 but if I the chance to scope it it would shoot snake-eyes. There are also markings on the stock disc that indicate the unit of assignment.
Those are great rifles. When you remove the stock, check on the left side of the action to see if you have any scope mounting holes drilled there. Someone, I think Savage T, correctly informed me of what the '42B' designation means - that they were arsenal reworked in the 50s. But I have always had a question about the 'B' designation as the M41B (bolt action 96) was the sniper rifle.
Now, all you have to do is lug that thing to the range and see how she shoots. Let us know. Mikey.
