About where should my free bore AOL be for shooting 75-77 gn. I'm getting a 7.7 twist bartlein barrel
thanks
 
0.0619 Wylde is plenty for the 77's. Best option will be to tell Bartlein you want to shoot the 77 SMK's, I'd venture they'll confirm the Wylde, but they'll tell you the best chamber they'd recommend.

By 75's, are you meaning the Bergers or the ELD's?
