This is from my re-configured CZ 457 MTR with a barrel and stock from a Premier that someone used for the basis of a build.

Bore-sighted and zeroed at 50. This was fired to determine 100 yard drop for shooting plates. An identical 8” target was placed directly above and used for the aiming point. Looks like the drop is 6.5”.

Target size and color helped with the hold, as did turning the FF down as low as it could be seen with no flare.

Is it shooting better than previously, assuming factory original then?

Way too early to know anything like that. I took it along on my weekly clays outing, leaving early to give me some time with it. I lucked into a dead-calm morning, which was really helpful. High rings for mounting a scope to clear the irons hadn’t arrived, so I put the FF on. I shot mostly SV, but also some RWS SSHP and two varieties of CCI Quiet. The Quiet Auto landed a touch low, but the RWS is right on. Once I figured the drop with the SV, the plates at 100 were dead meat from a rest; next will be trying offhand and from a sit or seated on a hunting seat.

The rear open sight is pretty close to my eye, so even with glasses I may have a tough time with them. The dot in the FF is very clear. I really like the handling with it so equipped, and may just shoot it like that. A scope will be handy for checking out ammo options. One YouTuber with a lot of CZ experience says that the sporter-chambered barrels may handle a wider variety of ammo well than the match ones, which can be fussier, and also will accept stuff like Stingers without issue. If I can shoot it well enough with either the irons or a RD for small game and plinking, I’d like to keep it like that instead of creating another optics-laden anvil. Switching back to the MTR for bench work is pretty simple, if I want to play that way.

I just picked up a CZ 457 today. It is in the factory configuration and I’m looking forward to shooting it. I’ve never gotten serious about rimfires I’ve just always plinked with my 77/22

Also need to decide on glass.

Well, I’m committed to the new configuration now. Feller came by and bought my MTR stock and barrel. He wants one that’s heavier. Go figure.

Not to bad for a 100 yds. I would be happy with that as a starting point.

The high rings I ordered came in so I can mount a scope and do some ammo testing. If I hold to my notion of using this as a small-game and woods-walker, my ammo choice will be the best-performing hollow points from my considerable supply. Shots would typically be at 25 yards or so. Pretty sure I’me going to replace the 3MOA FF with a 2MOA Romeo5 for its clearer dot and feature set.

Pappy will you post any pictures of the set up?
