If there’s something you don’t like about all that, you’re in luck. 22LR almost every day and I wish that joy for you all. I hope you’ll be quickly replacing that with the quality suppressor of your choice. 22LR out there, and ends with 1/2×28 threads and a thread protector. It’s got a 1:16 twist, like pretty much every.

What’s stayed the same from the 455 to the 457 is the barrel set system and the magazine. That reduces the overall weight of the receiver, as well as the rifle’s overall footprint. You’d have to be a pretty astute observer to notice, but along with flattened the sides of the receiver, CZ also removed an inch from its length as well. Again, a little experimentation was all it took and the results were immediate engagement while still remaining safe. The take-up adjustment is particularly nice. With a little bit of experimentation, it was pretty easy to get the trigger all the way down to a consistent 2 lbs.Īt that weight, the pull was light and crisp, and wouldn’t trip when I smacked the rifle hard or bounced it on a table. According to my Lyman Digital Trigger scale, the rifle came from the factory with the trigger set at 3 lbs, 8 oz. The 457’s trigger is adjustable for not just pull weight, but also for overtravel and take-up. Image courtesy JWT for .Īnother difference is the trigger. The 60 degree throw helps clear those larger bells and still provides plenty of room for your fingers to keep a hold of the bolt handle as you cycle it. But if you’re trying to reach tiny targets far away, an optic with higher magnification and a larger objective is likely on the menu.

If you’re running iron sights or a smaller magnification scope, this won’t mean much to you. Instead, the 457 includes a familiar right side receiver-mounted push-to-fire safety.Īlso welcome is the 60 degree bolt throw. It worked just fine, but was unfamiliar to most American shooters, and some shooters needed to bring their face off the gun to manipulate it. The 455 models had a kind of paddle safety mounted to the rear of the bolt. The most obvious change to the 455 models is the safety. But CZ listened to the American market for the updates they’ve made to the 457. The CZ 455 is legendary, and still to this day a great rimfire rifle. If there was any deformation of the round as it goes into the chamber, I couldn’t find it. I inspected the rounds as best as I could, including using a magnifying glass on soft lead bullets. Instead, there is some upward angle as the round leaves the magazine and the bolt presses the round in line with the chamber. Unlike say, the Vudoo Gun Works action, the CZ 457 doesn’t pick up the cartridge in line with the bore straight from the magazine. 22LR target rounds can be damaged by the feed ramp, making for an inconsistent bullet shape. That’s because the soft lead tips of many. Like several of the better rimfire receivers on the market, there is no feed ramp into the 457’s chamber. They both fired on the third go around, so the the ammunition is to blame there, not the guns. I had two rounds fail to fire, but they also failed to fire on the first shot when loaded into a Ruger Single Six revolver. I never had a case fail to load or extract. I cleaned and lubed the rifle before I started firing, and then not again until I was ready to shoot for groups, which was after that box of Herter’s. The first 500-round box of Herter’s rimfire ammunition was shot out of this gun in the blazing Texas August heat. If extraction problems are going to occur, it’s going to happen on hot, humid days with a dirty bore. The downside is that if the chamber is too tight, you’ll have problems with extraction. The upside to the MTR chamber and headspace is that the cartridge and bullet don’t have any space to cant one way or another prior to heading down the bore, improving consistency. If you’re shooting a 35 to 40 grain projectile, your bullet is probably engaging the lands.
