CZ 457 in .22lr

[srb08]

Last summer I picked up this CZ 457 in .22 LR.
I ordered a Vortex Diamond Back 4x16x44 AO scope, scope mount and rings at the same time.
I hadn't had time to shoot it, except to make sure it worked, until last week.
It only has a couple hundred rounds through it but so far I'm pleased.
After getting the scope dialed in at 50yds, I was shooting ragged holes, with an occasional flyer, with CCI SV ammo.
I look forward to trying it with some higher grade SK, Eley and Wolf ammo, when it warms up a bit.

Very nice rifle, look forward to hearing more about it. For some reason, I just now saw this thread.

I love my cz 455. Pretty accurate too, that's an 8.5"x11" printed target.

Nice...if you dont like it, send it to me and I'll like it for you @srb08

@srb08 have you done rimfire lot testing before? It looks like you have done plenty of loading. Not sure if you're aware but due to the inconsistency of rimfire the typical formula for accuracy is shoot groups with every lot number you can find, immediately discard those with poor standard deviation then graph the groups. If there are a few that are close go with the one with the tightest vertical group. Once you find the lot your gun likes buy a case or two. These guys are hip to the game and understand. anschutznorthamerica.com/uploads/1/9/9/7/19975381/rws_inventory_100219_list.pdf

How's the trigger and the ejection?

How's the trigger and the ejection?

The trigger is adjustable for pull weight, sear engagement and over travel.
I have mine set at 2lbs, which is where I like it. I've read of some going down to <1lb.
No problems at all with ejection but I haven't had a chance to shoot it a lot.

What ammo were you shooting and how far?
Is that a factory stainless barrel or aftermarket? I knew there were some factory stainless barrel 455's but didn't know they were threaded.
Nice looking gun!

RWS R50 Anniversary Lot # I don't remember and it's all the way downstairs. The barrel is a benchmark 2 groove with a cone breech machined by Dan Killough, it's almost creepy looking down the shiny almost smooth bore.

I haven't done any lot testing but am aware of it and why it's advantageous.
I haven't ventured in to the high end ammo, like R50. I shoot CCI SV, Aguila SV and Blazer, when dicking around. Wolf ME, Eley Target and several flavors of SK are my top drawer at the moment.
I'm taking baby steps.

 

[Spladle160]

I haven't bought any for a while but when I was I think the high end Eley, RWS and lapua were all roughly in the same ballpark. The only other one that seemed to occasionally produce "acceptable" results was federal gold medal match for half the cost but I could never find anyone to sell specific lot numbers of it. I really love the look of your rifle.

A little update. Earlier this year, while cleaning the barrel, I stuck a cleaning rod. Bore is tight, rod was oversized. I assumed it was a tight patch jag combo, so I tapped the rod slowly through. Took the jag off and expected to just pull the rod back out. Nope, it was stuck tight. Ended up having to drive the rod back out. Figured the barrel was toast. I had planned on ordering a Lilja barrel and not shooting the gun until I installed it. I changed my mind.
I shot it yesterday at 50 yds, with the bad barrel.
The group with the CCI SV is the first five shot group, after zeroing the scope.
That was the best group with that ammo but the others were pretty good as well.
I also shot a few groups with SK Std+. That ammo shows promise. I have some higher quality SK, Eley and Wolf ammo to try as well.
The gun shoots better now than before I stuck the rod.
I dumped the Lilja barrel plan.
This one's a keeper.

 

[FergusonTO35]

Awesome! Mebbe the stuck rod just burnished the bore a little? I've read of people using grit covered bullets to do the same thing.

That really is a great setup. Beautiful gun, plenty accurate. Super easy to use clear scope. Every little boys dream and many a squirrel and groundhogs nightmare.
