Your opinion please.

I replaced the trigger on my Wby Vanguard Sub MOA and it went from shooting 1/2 moa to 2.5 inches. I am thinking it is probably the tightening sequence and torque of the action screws. Could the trigger itself be the problem ?

There are 4 possible causes:
1. We Assume the trigger is smooth and without a lot of creep and the break is a surprise.
2. The ammo is the same as before and in general, you are duplicating a prior session no new variables except the trigger
3. Could be the stock and action are not securely linked up as you suggest. The recoil causes the steel to shift in the plastic/carbonfiber
4. You are the cause, flinching as the trigger breaks. Happens a lot. Did to me with my 243.

You could also have grabbed the scope during assembly-disassembly. Do you have an inch-pounds torque wrench? They come in a variety of styles and prices and it is helpful to have a vise or some means to secure the rifle. Check Amazon first then Sears then see if the local rental tool joint has one. Home Depot Maybe?

Good luck

Dave, Thank you for your reply.
The trigger is a Timney and with 0 creep and breaks crisp as a fresh tortilla chip.
The ammo is the pet load of a friend from whom I bought the gun. He reloads for me.
I'm sure I probably grabbed the scope. Since shooting it the other day I have purchased an inch-pound torque wrench. I think it is called fat wrench or something like that.
Could it be in the mounting of the trigger ? I wouldn't think so but what do I know ?

Nope, trigger should be okay.

Find out the inch-pounds. Remove the current screws. Be positve the threads are clean on the screw and in the action. Tighten them in increments, roughly 20-25% should be okay.

Worst case, remove new trigger and re-install old and see what happens.

Thanks, will do.

Make sure the body of the trigger isn't binding on anything. Some of the aftermarket triggers are wider than the factory ones and have a tendency to bind on the stock and/or trigger guard.

That's what comes to mind when you install something new. It could be binding but just my opinion.

no experience with that rifle but installing a Timney 510 in a Rem 700 lots of times will require removing some wood or plastic from the stock or the trigger will bind and could cause accuracy issues,,I have seen some that would not even function without some stock mods,,,

making sure the safety and all of the trigger box is clearing the stock AND bottom metal would be my first check,,
