A few questions about my new model 10TR and about barrel break in

[RP12]

Which one of the fluted bolt bodies, the SSS "fishnet" or the PTG spiral? Do NOT get a straight flute, Savage found it grinds on the rounds below.

What length barrel did you get, the 20 or 25 inch ones?

Yes you will have to reset the head space, easy job with Go/NO Go gages and the Savage nut wrench.

A really cool tactical aluminum chassis would be cool, but won't make it shoot better.

You got a GREAT DEAL, enjoy them.

You can order the Tubbs finishing system could possibly help some. I just shot mine and cleaned every 20 rounds. Shoots 126, 147, 150, 155, 168, and 175 grain bullets ALL sub MOA. Really likes the 168 and 175 SMKs.
See above! I am not touching anything as it is perfect for me.

Not unless you want to shoot 0.19 MOA all the time. That is my best 4 shot group.

No you do "not" have to reset head space, if you only change the bolt body. If you send them out, just make sure you put the same bolt back in. Just match the serial #'s. Hence the reason they don't put the serial # on the rest of the bolt parts.
