Is the bolt-stop mod in one of those Montucky threads? Gotta look for that.

Now, back to the Creed..
Any more input for twist and number of grooves? Now looking at shooting the Hornady 140amax ammo, and reloading berger 140gr vld.

Chamber for the factory knowing I can get to the lands with the vld? Or chamber for the vld, hoping that the factory will shoot?

Thanks
