Good luck with those pivot bases. I've never trusted them as far as I could throw them. When I worked at the rifle range, next to $20.00 Tasco scopes, those pivot bases were the biggest culprit for lack of consistent groupings. Especially the older ones. I think the lock plates just didn't do a good job on them.
Late to the party, I've been prepping a bunch of .308 brass.
I'm in Whelen Nuts camp on this one, without a doubt. Same as Whelen Nut I've used them for years on rifles and 12 gauge slug guns, have swung them back and forth and they've always held zero.
Of course, I could see an issue IF the person didn't have the locking screws locked in tightly, but of course, that's about equivalent of not tightening a regular base and rings.
**** Whelen Nut, if Tom doesn't find that base/rings for you, shoot me a PM.
