About the Weatherby

In 1945, Roy Weatherby made it his mission to bring the idea of “one shot-kills are best achieved with high-speed and lightweight bullets” into the world of cartridge and rifle making. Ergo, he opened a Weatherby’s Sporting Goods shop in California. This was a humble beginning of the world’s prominent mark on the gun industry.

Travelling back in time, to the 1940s, this is when Weatherby began his cartridge business. These paved the way for a vast development in ballistics. Some of his cartridges, including the .257 and .270 Weatherby Magnums, remain the fastest in their calibre class and are still in production today.

While Weatherby’s cartridge business grew, there was also a need for a bolt-action capable of handling the magnum power. And this is how the legend – the strongest bolt-action rifle Mark V – was born. Soon after, others followed. In the 1960s the company added a line of shotguns called Orion and Athena, a Patrician pump, and Centurion semi-automatics.

Weatherby, Inc. was in for a crazy ride, as in May of 1961, Fred Jennie helped create a prototype model .22 rimfire rifle, which went by the name Mark XXII. The Vanguard rifles were then introduced for some of the world’s most popular big game and varmint cartridges. Weatherby’s son Ed was passed the torch and took over the company in 1983, but he held on to the rifle’s typical looks and the characteristics of being reliable and well-made.

Weatherby MK XXII Rifle Review

Weatherby MK XXII is a semi-auto rifle first introduced in 1961 and manufactured until 1989. It was launched again in 2007 as a bolt-action instead of semi-auto. Initially, there were two versions of MK XXII available, the primary difference between the two being the loading mechanism as one version used the tubular and the other a detachable box-type magazine.

The rifle features a deep-blued barrel and a round bolt in a receiver which is made of a durable alloy. Another useful feature is a lever positioned on the right rear of the action that can switch the weapon from semiauto to single-shot mode. The trigger has a light pull of 1134 g (2.5lb) and comes pre-set at the factory. There is a two-position safety catch placed on the right upper side of the receiver that is easily reachable with a thumb.

The possible barrel length for Weatherby MK XXII is 610 mm (24-inch).

Which Rifles Have Interchangeable Mounts

Two-piece mounts

For two-piece mounts to fit on a rifle, mounting surfaces must match in all dimensions except the B distance. B distance can vary because two-piece mounts can be installed and adjusted closer or further apart.

One-piece mounts

For one-piece mounts to fit on a rifle, mounting surfaces on these rifles must match in every dimension.

Unfortunately, we currently lack information regarding interchangeable mounts for the Weatherby MK XXII rifle. Should you have any additional information regarding possible mount matches, please contact us. We would gladly accept your help and expand our database accordingly.

There are two terms found for similar thing: quick release scope mounts and quick detach scope mounts. Term quick release scope mounts is used mostly in Europe and quick detach scope mounts is used mainly in USA, although they mean the same thing. With these terms we describe a scope mount that can be quickly removed from the rifle in the field without using any tools and quickly attached back on the rifle when needed.

Main advantages:

possibility to use multiple scopes on the rifle,
easy transportation of the scope and the rifle separately,
if scope fails, it is possible to immediately detach it and use iron sights.

FIXED vs DETACHABLE scope mounts

Fixed scope mounts are mounted to the rifle with screws and sometimes even with glue. This means that it is impossible to attach or detach the scope mount using bare hands without using tools. It also means that they are not meant for constantly being attached on or detached off the rifle. Once you screw the mount on the rifle, it normally stays there for a longer period of use.

Detachable scope mounts offer possibility to attach or detach them without using any tools. This is extremely handy while transporting the rifle and the scope separately and it also offers multiple solutions of different optics on the same rifle. Detachable scope mounts can be attached or detached from the rifle in a matter of seconds, using bare hands.

DETACHABLE vs REPEATABLE scope mounts

It is important to know and understand expressions “detachable” and “repeatable” while talking about scope mounts. Term detachable scope mounts implies scope mounts that can be quickly attached or detached without using any tools. However, when you detach this kind of mount and attach it back on the rifle, it is recommended to zero the rifle before using it again. Procedure of detaching and again attaching the mount will probably need a sighting in before next shooting, because mount will not be secured on the rifle in the perfectly same position and conditions as it was before detaching it off the rifle.

On the contrary, repeatable scope mounts are most sophisticated mounts. These scope mounts are also detachable, however – they provide removing scope from the rifle and attaching it back again without zeroing the rifle every time. This means that they are made more precisely and that they are offering a possibility of using different optical sights / scope on the same rifle. These mounts are ideal for hunters who can use optical and iron sights interchangeably, depending on the needs in different situations. With the repeatable scope mounts, it is useful to keep them oiled as well as the upper part of the rifle, so that repeatability is more ensured. With a touch of oil, the repeatability might be better, because parts of the mount will always return to their previous locations.

Different types of repeatable scope mounts:

Pivot mounts,
Dentler mounts,
Picatinny repeatable mounts,
12 mm dovetail repeatable mounts (for break barrel rifles, such as Steyr Duett, Blaser B750, Fair Combi, Fair SLX 800, Bettinsoli rifles, etc.),
Original repeatable mounts, made by manufacturers of rifles for their rifles (Blaser mount, Sauer SUM mount, Mauser M03 mount, Steyr Monoblock mount, etc.).

TIP OFF / ROLL OFF vs SLIDE ON mounts

Nowadays, there are a whole lot of different possibilities, made for attaching riflescopes on the rifles. There are also a lot of different expressions, having the same meaning. It is good to know that tip off and roll off mounts are basically the same thing. They represent quick release scope mounts for dovetails and rails which can be rolled or tipped off the rail vertically to the side of the rail. On the contrary, there are also slide on mounts available on the market. They represent quick release scope mounts that can be slided on or off the rail or dovetail from front or rear side of the rail / dovetail. All of these expressions are mainly used for separate rings that can be attached to the rails / dovetails. As far as functioning the rifle, it does not matter which one of these mounts you choose – tip / roll off or slide on mounts. If they are installed correctly, they are all going to work. However, the main difference between them is the principle of attaching them on rails on dovetails.
