Very interesting thread.I am curious what twist barrel was used.I would assume it is a 12. I have a 20 Tactical improved that has a 13
which offers a bit more speed/accuracy.I wonder what the original Remmy's used for twist rate.I would'nt be surprised if it was a 13
to take full advantage of the shorter original bullets.Anybody ever checked their twist rate or have any old specs/info?

I got a 2376 average with the white box ammo back in 2011. It seems that this is just about the ballpark for the white box rounds.

Very interesting....I'll have to try both types over the chrono out of my 592 just to see wassup. Evidently they're a bit hotter than Aguila shows, which is great.

I got the stock directly from the CZ-USA store: http://shop.cz-usa.c...39/RIMFIRE.aspx

Make sure you confirm which stock will work with your rifle.

Do you have the video up yet? I have a CZ American. I am excited about this as I was thinking of buying a BSA Martini and have it rebarreled. The CZ I have now is way to accurate to mess with but I have no problem getting another!

So thought i'd kick this up again as its only 6 years old.

Eric did you take this any further for a repeater?

Since this time the 457 has hit the market would this be an option not sure on how many locking lugs the new rifle has.

 

This forum has been to quiet for a long time you blokes now have plenty of ammo so how about posting stuff again
