New to site but not new to savage

I recently purchased 2 new 12F's for my fiancé and myself in 6br Norma. So far since we started using them we've won a few matches, and expect to keep doing better. We love our rifles getting group sizes from 2.5"-3.25" at 600yds. In a little over 3 months we've gone threw 1500 rounds of 107 SMK's between the two of us. Since those are now gone I decided to see if we can up are groups using 105 Bergers hybrid target bullets.
My question is what are your thoughts of upgrading our barrels to barline's, and PTG bolt heads, as well as looking into bedding the actions. Anyone who has done any or all the above that can tell me if their results paid off or weren't nessasary.
Oh were using varget 30.8 gr, and CCI 450's with lapua brass
i use a sightron 10-50 and she uses a bushnell 8-30 elite tactical
20moa rails
our previous rifles used for the shoot were my 110ba 300 win mag and she was using a 223 model 12 then went to a 398 fcp for the 600yd matches
