Recently put a 7-08 barrel on my savage striker and the Holland radial baffle brake is aligning upside down. Does anyone know knows how much thicker lug I need to rotate barrel 180 degrees.
I'm afraid you won't get that done by changing the thickness of the recoil lug.
Your headspace is set and a thicker lug will not affect the alignment of your radial brake.
You may need to use a self timing brake to time baffles correctly.
Brownells or Ebay will have shims for the muzzle brake. thicker lug won't solve problem as noted above. full rotation of a savage barrel is .050 just for your info
