cz 457 varmint mtr

[Hozzie]

Just a heads-up for CZ owners. While reinstalling the barreled action after replacing the original trigger, I noticed the plastic sleeve that the magazine comes up through, was broken. The front anchor point was apparently crushed. I have never torqued the action screws tighter than 25 ft. Lbs. That $9 part costs over $20 with the shipping. While I had the service gentleman on the line, I voiced my negative opinion of their original trigger. That apparently didn’t sit too well.

I hope you mean 25 IN/lb?

If I were to buy a new .22, I think I’d get the Bergera 14. At the Lapua test site in Marengo, Ohio, my buddy’s handily outshot my CZ 457 MTR.

Which ammo's were tested?

Oops.

Lapua up to Center X. That had reached my price ceiling.

ARA Factory matches are loving the CZ's.
Factory class has to be a current production rifle that's under $1000. 457 must be the best factory shooter out there to meet this requirement.

For those interested to look up the stats I noted the process below.

Unless I overlooked, I noticed that the site only shows the equipment used under the National Tournaments.

I shot with Three of those guys last week including the winner. They’re some good shooters indeed. I beat them all on the first card. Then they proceeded to smoke me.

My CZ 457 Varmint has a 45X Muller Scope and a Yo-Dave trigger spring, along with a slight tweek of sear engagement for a 11-12 oz. trigger pull. With a EMG cantalever bag rider and it's favorite RWS R-50 ammo it easily groups sub-0.5" at 50 yards when I don't screw it up. I am hoping to clean an IBS BR-50 target next chance I get. It can't quite beat my Walther target rifle but can stay with my Savage-Anschutz one. Other CZ owners are also very competitive with their rifles.

Rimfireshooter;
Thank you for the reply.

I should have never got a borescope...
Inside the muzzle seems to have the barrel coating in the bore at the last 1/4 - 1/2" of the muzzle.

What do you all think about this?

Looks like some blueing salts got into the bore at the muzzle. Probably won't hurt accuracy.

Thanks, just noticed mine was the same. Front screw hole was broken. I dont know why I didnt see it sooner. It does blend in with the part. I was also focused on other issues.

The new trigger has been weight tested this week. Using the digital Wheeler scale, a ten shot string averaged 2.6 oz. If the wind settles down in the next few days, I hope to give it an extended test session.
