I have a T3 in 300wsm - the recoil lug get severlely 'peened' after 20-30 rounds, so much so that I have flipped or rotated it often to keep a smooth or the smoothest side in the groove. I am at the point now where the lug is in need of replacement after 100 rnds. Has anyone had a steel block / lug made up to replace the aluminum one??? Any issues?
Sadly it shoots OK, not MOA consistently yet (one cloverleaf followed by a couple 2-3moa followed by a cloverleaf...), but everytime I have flipped or rotated the lug, the POI changes dramatically! I know it shouldnt, but the worst was 12" at 100yds after flipping it, rotating is only about 6" change. This is with it seated properly, and screws torqued to 35.
I figure its getting peened due to movement, so after I get this lug thing tweaked I am going to bed the pillars, action, and lug with a thin thin skim coat of devcon to hopefully stop things from moving. There is very little info on bedding T3's, so again, any thoughts, issues, precautions would be greatly appreciated!
Thx
