FishBox,
Should be a shooter. Would love to have one. I did a quick search of MidwayUSA and available 20MOA Picatinny's for Savage SA round back are:
Nightforce - $116.00
TPS - $86.33
EGW - $45.00
Weaver - $35.00
EGW Heavy Duty - $70.00 (not sure what's going on with this, both are aluminum)
Badg Ord - $150.00
Seekins - $95.00
Valdada IOR - $95.00
Leupold Mk - $59.00 (on sale right now - says it's 8-40 adaptable - again, not sure)
That's a pretty good selection with a lot of the hard hitters. I do not have enough experience with picatinny mounting systems to recommend the cheaper over the more expensive, or vice versa, but my mind says a rail is a rail. If I were not on a budget I would purchase NF or BadgOrd. though.
I recently (last week) bought a LA Weaver 20MOA and medium tactical (6 screw) rings for my Savage 112BVSS/VLP in 6.5-284 w/NF NXS 5.5-22x56. I swapped the factory fluted barrel (26") out for a 28" Lothar Walther non-fluted and the old mount/rings (Leupold STD long range/Burris Signature STD) let the scope's objective rub.
I originally bought High rings as the package read something like, "for Objective lens up to 56mm". Didn't like the space (.466") between scope and barrel so I took them back and got the med. Now it's about .125", much better IMO (easier on my neck anyway).
Sorry for the rambling, hopefully some of it will be a use. HAGO
