My son has a BDL in 270 (I orignally bought it in 1968) and gave it to him. He has an XCR II in 375 H&H now and we're going to replace the trigger with a Walker so it locks the bolt. He had the bolt open on him bear hunting, didn't like it. I don't blame him.
To do that conversion, a slot needs to be milled into the action for the locking lever to pass through. The underside of the bolt needs a shallow mill cut so the locking safety lever can engage it and keep the bolt from rotating. It's pretty basic work for a 'smith familiar with these. You'll also need the early pre '68 safety lever to go with the original style 700 trigger. It's a worthwhile modification for 700's that are hunted in rough and tumble stuff.
Good shootin' -Al
