CZ 457

No bueno for PRS.Just an FYI, the 25-round mags "for" the 512 should work in 455-457s if you're looking for more shots - and don't care about the 'big banana' hanging there
Not sure what happened here......maybe bore cleaning solvent....maybe tightened too much at one point. Never had an issue before.
That being said...the DIP aluminum components fit great, no mag feeding issues at all, and very well made. I'm about to swap these into my other 2 rifles and do have a PRS on Sat to really test it.
Glad I bought 3 of each. I also did go with the extended mag block since I was already in there anyways.
Hey guys. I ordered a VPT MTR from my dealer 7 months ago and still no word on when it might be in. Does anyone have close ties to either CZ or Manners and have an idea about what the hang up might be? I'd greatly appreciate some insider information.
I wasn't planning on messing with my PRS rifle the day before a match, but.....the aluminum magwell, and block took just a few minutes to swap out.
Great quality and no more plastic to potentially fail.....The DIP products are cheap and easy insurance well worth it.

I went shooting last Wednesday after work.
I have a 20” CZ 457 At-One with the Match chamber the same as the MTR
It is threaded 1/2”x 20 unlike the US spec. rifles which are threaded 1/2”x 28.
I installed it in an MDT XRS chassis after the MDT Black Friday sale but I didn't have a chance to shoot it till now.
I was shooting at a distance of 25M at an indoor range.
I was testing various types of ammo and I was blown away by this particular group.
It is not indicative of what the rifle can typically do but it impressed me just the same.
All groups are 5 shots.

Looks good, I’d like to see how it does at 50.
Hopefully in another month or so the snow should be gone from the outdoor range.
I have 40M available indoor.

Can you change barrels say from a 17hmr to a 22lr barrel without having to change anything else? On the cz 457
I can't even fathom what that would look like.
You should not be that far forward. The balance point should be in front of the mag well/ release.
Just joined the group. I installed a Lilja barrel in my 457VPT this week. First trip to the range in months and shot my first 2500 card. Scope is Athlon Argos 10-40 X 56. Short little 16.5" barrel is impressive .
My other CZ is a 457 Varmint with a MTR barrel installed.

You're not wrong, but do you own or have you shot the pro varmint? Your comment leads me to believe you don't/haven't. It won't do that without modification which is why I am asking what others have done.
The 16" 457 pro varmint in the factory boyds varmint stock won't even come close to balancing in front of the magwell - AFTER I melted lead and filled the empty channel underneath the barrel that is in the factory stock. That is why I am asking. So when the rifle is placed far enough up onto a game changer the mag acts like a pivot. This is my daughter's rifle, so trying to get it right.
My next step is to add 1/2" steel bar to the sides of the forearm like folks do on some chassis. The setup includes an area 419 pic rail and a Vortex g2 pst 3-15x44.
Just looking to see what others may have tried that was successful.
I have shot one or two but it's been awhile. It's probably try an all steel arca to start since you added the lead, although I'd have gone with a lilja .900 straight barrel to begin with before anything else. They are the single biggest upgrade, before great glass, since good ammo is a given.
I've got a 24" 'At One' in a KRG Bravo. Thinking hard about a Varmint 20" and either sticking that in the KRG or buying a 2nd KRG and using the 'At One' in the backyard with the suppressor on it
The longer barrel seems OK in MARS matches, but I only have the one rimfire and 'two is one and one is none.'
...or am I bonkers?

Back to the range today. Beautiful day cool, sunny, and no wind in NC today. Shooting Federal Ultramatch. 457 VPT Lilja barrel shooting the ARA unlimited target for the first time. If you get sloppy with your technique it will surely show up! Ended up with 2025 target. To much fun!
Made a few changes before my PRS match tomorrow.

It's 'new rifle day!' Woot!
Just picked up another 457. This time in Varmint.
The KRG Bravo is already here. The DIP Picatinny rail is here. The Silent Thunder magwell bit is here.
Only thing that's not here is an ARCA rail.
The downside to the Varmint barrel is that there's no threading for a suppressor. Aah well. There's always the At-One that I put the suppressor on for backyard practice rifle.

The match went ok to be honest, it’s not like I expected the chassis to give me ten extra points.
It was also much more difficult than the last one, lots of moving from one end to the other of barricades , lots of panning along troop lines at distances.
One was a 3 target troop line with the last being a KYL target that in prone wasn’t really visible on purpose through tall grass. 15rd. The smaller ones most people timed out on.
Overall I’m happy, but waiting on side rails for the MPA chassis. I have Manners on all my centerfire stuff and love those. I also need to mentally run through stages better which comes with going out and competing and watching.
It was my 4th PRS match.

Ordered a steel 10-rounder mag from CZparts as plastic ones were out of stock. Expensive, but really well made in my opinion. Heavier and better quality than similar mags by Savage. Plastic and metal mags:
Interdasting. Going to be reloading mags for my dad tomorrow....once he gets started on the CZ it's all I can do to keep a mag full.....you shoot these metal ones yet? I could use a few more
I wish someone would make these 15rd ones available for here in the States......

Just came in last night. I’ll probably get out on Monday and will report back.
Personally, I've found my 24" At-one will shoot with ANY of my heavy barreled CZ's between 50 and 100 yds. ( Even my former MTR). The 24" mid taper is also very popular with the ARA guys so that tells you something.
Sighted in the scope on the new Varmint this afternoon. You may be right, but moving that extra 4" out of barricades makes things 'interesting.' Here's hoping that the shorter barrel will make that easier.
I'm not very good at making good positions yet, so all the help I can get is needed

I’ve been wanting to get into rimfire for a while and finally made it happen this week. The side hustle finally generated enough gun funds. Picked up a plain Jane CZ457 Varmint, added an Area 419 ARCA rail, bolt knob, and 50 MOA base. Also added the Timney trigger, Matthews Fab cheek riser, and topped with an Arken EP5. SK match looks like it wants to shoot so I’m going to run that for now.
What type of accuracy with rimfire do you need for say PRS 22 or NRL22? I’m assuming sub minute is good enough just like center fire

Moa is fine. A lot of targets are 2moa or bigger.
