CZ Model 455 .17 HMR and .22 LR American Combo Rifle

CZ USA 455 American combo 17 hmr 22LR .22 Long rifle

Any experienced varmint hunter knows the value of a good .17 HMR rifle, particular when used inside 150 yards on small critters such as ground squirrels. The .17 HMR is a great round, but for general plinking and target practice, we prefer shooting the venerable .22 Long Rifle. The .22 LR has less recoil and less noise. Importantly, .22 LR ammo (even with today’s shortages) remains much less expensive than .17 HMR ammunition.

Wouldn’t it be great if a single, affordable varmint rifle could shoot both .22 LR and .17 HMR? Well, CZ offers just such a rig — the CZ Model 455 American Combo, a versatile switch-caliber rifle priced at about $485.00 (MSRP is $531.00). The American Combo comes complete with both .22 LR and .17 HMR barrels, easily interchanged with a simple Allen wrench. As CZ explains: “The CZ 455 eliminates the need to spend the extra expense on a second rifle when you want to add another quality shooter to your rimfire battery”. For a bit more money, you can even purchase a .22 WMR barrel, making your CZ a triple-threat varmint-slayer.

Ruger Releases New Bolt Action Rimfire Rifles

Ruger recently announced the new Ruger American Rimfire™ series of bolt-action rimfire rifles, chambered in .22LR or .22 Magnum. These rifles feature an interesting convertible polymer stock and the .22LR versions can run 10/22 magazines. You could say the new rifles borrow features from the centerfire Ruger American Rifle® series, while offering mag interchangeability with 10/22 rimfire rifle. Ruger offers both full-sized (22″ barrel/13.75″ length of pull) and compact (18″ barrel/12.5″ length of pull) models, both of which are available in either .22 LR or .22 Magnum. All models have a suggested retail price of $329.00.

.22LR Models Can Use All 10/22 Magazines
Models chambered in .22LR feature the detachable, flush-mounted 10/22® BX1 10-round rotary magazine and accept all 10/22® magazines. Models chambered in .22 Magnum use the detachable, flush-mounted JMX1 9-round rotary magazine.

Dove-Tailed Action and Bolt with 60° Bolt Throw
Standard 3/8″ dovetails for rimfire rings are milled into the actions, which are also drilled and tapped for mounting Weaver-style bases. The 60-degree bolt can be removed with an easy-to-use, receiver-mounted bolt release that does NOT require a pull of the trigger.

Integral Bedding Block for Action
The new rimfire rifles also feature a patent-pending Power Bedding® integral bedding block system that positively locates the receiver and free floats the barrel. Additional features include a blued, hammer-forged barrel with fiber optic front sight and adjustable, folding leaf rear sight.

1885 High Wall Dressed Up for Varminting

22 WMR Magnum rimfireForum member David K. (aka “mongochicago”) displayed a handsome 1919-vintage 1885 Winchester High Wall in our Forum Rimfire Gallery. The 91-year-old rimfire has been transformed from stem to stern with a new barrel, engraving on the receiver, and stunning exhibition-grade walnut fore-arm and buttstock.

The beautiful wood comes from Ballard Rifle & Cartridge Co. of Cody, Wyoming. Shilen Rifles provided the new blued octagon barrel (chambered in 22 Magnum). David tells us: “This is an 1885 Winchester made in 1919 that I customized for prairie dog shooting. The gunsmith was Mark Stratton, and the engraving was done by Darrel B. Nelson.”
