Picked up a Knight Ultra-lite 50 cal , nitride finish bare 209 , I'm in upstate NY so It's getting a Leupold 2.5-8 VX-3. like the gun , question is priming ? That opening between the bolt face cutaway and the breechplug nipple is awful tiny . I know they make a tri-finger tool . Is that the best choice for this gun. Thank You...
