The LRP’s stock is unlike anything CZ offers. No one will say there’s not enough ball to grab, no matter how fast the shooter desires to work the action. Shooting rimfire rifles out to 300 yards is not uncommon these days, and the 25-MOA bias allows most variable-powered optics to dial for elevation out to 300.Īlmost as if it were a cartoon caricature, the LRP’s bolt handle is a large rubber ball that’s impossible to miss. This declined bias allows a scope, once sighted in, to have the majority of its travel available to dial for targets at longer distances. The LRP comes with a Weaver-style rail attached to the receiver, which has a 25-MOA downward bias. At no time during testing did any bullet engrave so aggressively that the bolt wouldn’t extract a live round. Bullets that touch the lands also allow each cartridge to build consistent pressure when fired, yielding better extreme spreads and lower standard deviations. Having the bullet touching the lands is part of the reason accuracy is so good in this rifle it keeps the bullet from yawing prior to engraving in the rifling. Rimfire ammunition feeds and cycles just fine through the match chamber, but most bullets will engrave in the rifling by simply closing the bolt.
22 LR rounds like the CCI Stinger may require some effort to close the bolt for some users. 22 LR ammunition that is of reasonable quality, but longer. This minimum-dimensioned chamber fires almost all. The barrel on the LRP is 20 inches long, fluted, has a 1:16-inch twist rate, a ½-28 threaded muzzle, and CZ’s MTR chamber. Either will accept a traditional sling swivel, but the second can be used to mount a bipod. Two sling stud attachment points are available at the forend. If running the bolt quickly in adverse conditions yields a “dead trigger,” the sear failed to catch the cocking piece. Triggers with so little sear engagement may not only be unsafe, they also have a tendency to stop working when shooting conditions deteriorate. If the firing pin drops, there isn’t enough sear engagement. Any adjustment of sear engagement should be done in small increments with periodic safety checks performed by smacking the butt of the rifle on the ground with the firing pin cocked on a confirmed empty chamber. Additionally, the sear engagement is adjustable and allows the shooter to remove all discernable creep. Weight on a factory 457 trigger adjusts down to about 11/2 pounds, and using an aftermarket spring kit as well can bring it down to less than a pound. The 457 trigger, on the other hand, is user adjustable for both weight and sear engagement. The 455 trigger was only tunable through the use of aftermarket spring kits, and trigger companies developed aftermarket solutions for those desiring sub-2-pound let-off. Perhaps the greatest improvement the 457 offers over the 455 is the trigger. A rear monopod can also be attached to the toe’s accessory rail The 457 LRP features a beech stock that’s complete with a prominent rear hook designed to cradle the shooter’s support hand. The safety was also moved from the bolt shroud on the 455 to the side of the receiver on the 457, making it a more familiar arrangment for American consumers. Since rimfire rifles don’t require a lot of firing-pin spring weight to fire a cartridge, the shorter lift remains light. CZ’s decision to go to a three-lug action on the 457 gave it a shorter 60-degree lift, leaving plenty of room for the firing hand on the bolt handle throughout the cycle. The smaller size of rimfire actions meant the short bolt handle could come uncomfortably close to the scope’s ocular housing when the action was cycled. The 455 was a two-lug action with 90-degrees of bolt lift and a safety attached to the bolt shroud. The 457 action is an improvement over the 455 it replaced in 2018. However, force required to manipulate the trigger can be increased to 3.37 pounds. The trigger installed in all CZ 457 models is adjustable for lighter trigger pulls, as little as 1.8 pounds in fact.
CZ put its MTR chamber in a 20-inch barrel, and paired it with an improved stock that’s more appropriate for prone, bench and positional shooting. One of CZ’s newest 457 models, and the subject of this review, is the Long Range Precision (LRP) model. (CIP is the European equivalent to the Sporting Arms and Ammunition Manufacturers’ Institute, or SAAMI.) Tighter chambers are critical in rimfire rifles to produce accuracy, so this is the tightest standard chamber a manufacturer can put in a rifle. The CZ 457 Match Target Rifle (MTR) came along in 2020 and used a match chamber cut to minimum dimensions per Commission internationale permanente (CIP). CZ’s rimfire rifle continues to evolve with the creation of the CZ 457 in 2019.
