CZ 457 Match vs Standard Chamber 22lr?

[Boyandhisdogs]

I want a long range precision .22lr rifle and have decided on the CZ 457 after lots of window shopping and reading reviews. I only want to shoot recreationally and some local events but not serious competition. I really like the Varmint MTR (love that fancy wood stock) but it has a non-threaded 20" barrel. I was really hoping for a 16" threaded barrel because I intend to only shoot standard velocity or subsonics out of this rifle, so I don't need the extra burn time and I do want to use a suppressor in the future so threads are a must and a shorter barrel would be really nice.

The ProVarmint Suppressor Ready model has a 16.5" threaded heavy barrel, which is exactly what I want, but it has a standard chamber rather than a match chamber. Will this significantly affect accuracy in real world conditions? I don't plan on shooting super expensive match ammo all the time, I was hoping to get away with shooting higher quality bulk or mid-grade, match-ish ammo.

It'll be a couple hundred dollars cheaper to swap the stock on a ProVarmint than it would be to swap barrels on the MTR or have it cut and threaded. The only difference in the end would be the chamber.

Some CZ discussion here:

Match chamber vs standard chamber?

Is there really that much difference? I have a CZ Precision Trainer and it has the standard chamber. I heard today that someone can modify it and make it a match chamber. My rifle shoots very good the way it is. Am I going to notice that much better accuracy vs what I am getting now? If I was...

In my sample of ONE the match chamber made no difference. Only when I stepped up to a Lilja barrel did I see significant improvement. Both the factory CZ barrels I shot were 1/2" shooters at 50 yards with CCI Standard Velocity.

I have the leftover 16.5" pro varmint suppressor ready barrel and stock with bottom metal and a few extra magazines if you want to build something down the road. I wen't away from the CZ 457 so I don't need them anymore, and would sell them on the cheap to someone who could use them....

That's good to know, and I was thinking along the same lines. I expect the difference between factory match vs factory standard chambers will be very small, and aftermarket will be better than both.

So maybe I go with the standard chamber and if I really need more, then aftermarket would be the best anyway.
