Upgrades to a stock bolt action rifle .

getting a chassis or a suppressor, or a nice muzzle brake will help. MDT makes great chassis. I'd also suggest taking a course on reloading to learn to use Gordon's Reloading Tool, to eliminate ammo guesswork and being able to go "off-book".

Ok so here's where I'm at CZ carbine stock with a 24" Pac-Nor match grade barrel 1-7.5 twist, threaded with a Eric Cortina muzzle brake/Tuner a factory set trigger that has been worked with a Leupold  VX-5HD 3 x 15 side focus firedot scope and am in the process of bedding . I really cannot think of anything else to do except work up a good load for this gun and shoot

I don't know if the CZ527 carbine and the CZ527 American have the same stock , The carbine seems a little shorter but I have only seen pictures of the American version . But I don't think I could find a lighter better stock once it has been bedded.

I just started reloading , don't know much yet but trying , never heard of Gordon's Reloading tool will have to look that up

This is just my thoughts, based upon research and several series of testing by Applied Ballistics and Reloading All Day, but Tuners simply don't work, and functionally work the same as a muzzle brake. Harmonics theory is not the foremost influence to accuracy or precision when shooting groups. The rest all looks good. Balancing the rifle will help with handling too if you intend to do PRS sort of stuff, otherwise not needed.

The beauty behind having a bolt gun rather than an AR15 is that you're able to take full advantage of the cartridges capabilities, and not limited to that 52k PSI from bolt thrust issues, and can take the full breadth up to 62k PSI. I'm trying to get a 6mm Arc bolt gun too

As for reloading, and that gordon's reloading tool, you NEED to calibrate it for it to be anywhere accurate, and not run into any blown up actions or other issues. If you want good standard deviations on your shots, and creating less dispersion on your target, try for at least 95% case fill and 100% burn rate across all temperature ranges. You can do ladder tests on the fly to get rid of guesswork and save money too, as well observe the effects of temperature on your powder and how that influences your pressure increase or decrease. just as an example.. the attachment is a simulated model of a 14.5" 6mm ARC in a gas gun with 105gr Bergers using 25gr of AA2230 at 100°F. again, NEED to calibrate. opening it to a new tab will help see the whole image. You will not find AA2230 in any reloading book or data out there for 6mm ARC, from my observations and research.
