is there a measurable difference in accuracy between rifle actions with integral recoil lug and those that are pinned or get installed with the barrel? Buying custom actions is not easy for left handed people. Have Bighorn SR3 and Mausingfield. And a Deviant Hunter on order. Those with loose lug can be had from the volume builders. They are less money but is there a compromise in accuracy? I do understand the integral is better just from being stronger as a one piece unit. Thoughts please and thank you.
