I've pretty much done the same to my 77/17 and can get sub 1/2 MOA with 20gr reloads and factory 15.5 NTX.Hope to get out tmw and shoot it.
Glass bedded it
Free floated the barrel
Shimmed the bolt
Replaced sear and trigger spring with Volquartsen.
The Volquartsen kit reduced the pull from 5 plus pounds to 2.75 pounds and there’s little or no creep.
I see now that Federal is making ammunition for the 17 Hornet. Anyone tried this yet?
