I ordered a new Timney Trigger for a Wby Mark V and I'm having issues with it. It was set at factory to about a 2.5lb pull weight. Got the trigger installed and it slam fires every time I close the bolt, even gently. So I increased to maximum pull weight which helped a little but not enough. Beyond adjusting the pull weight I would rather not tinker with sear engagement. Had this problem before where max pull weight doesn't do it?
