I try to pin all of my Rem type lugs but for those that aren't I do something that will probably get me into trouble on the Forum.
I make an index mark on the lug and the action. When screwing on a barrel I try to keep the marks lined up as much as possible. Sometimes it works, and sometimes not. When the barrel is nearly tight, I take a lead hammer and gently pound the lug into position. Then, a final twist of the action wrench. It usually stays put.
And just so you know, when I bed a Rem 700 I leave a lot of clearance on the sides, bottom, and front of the lug. It's been my experience that a lug that is a leetle bit out of alignment doesn't hurt a thing.
