    I have been looking into a .22 rifle due to costs of shooting. Originally I was looking at the marlin 795, and I still may choose it. But, I have been seeing .22lr and .22 magnum at my local stores. Is there a rifle that will chamber both? What I like about the marlin is its only about 165 OTD.

    They use exactly the same size bore, but they use two different chamber lengths and diameters. So unless you can find a .22 rifle with swappable barrels (like a Rossi or Thompson/Center) you most likely won't be able to find a rifle that shoots both. The .22lr uses a "heeled" bullet which allows the case to be the same diameter as the bullet, while the bullet on the .22 mag. is not "heeled" thus the case diameter is larger than the bullet, thus requiring a chamber that is larger in diameter than the .22lr.

    A couple of manufacturers make revolvers with interchangeable cylinders which allows for the disparity in chambers sizes, while still allowing for both the .22lr and the .22mag to be fired from the same gun barrel.

    If a swappable barrel style rifle ends up being your choice, I would recommend that the second barrel be something other than the .22mag, since the magnum .22 is a rimfire round it is not reloadable, and its cost tends to be quite high (comparatively) per box. You might be better served by having a second barrel that uses a center-fire round so that it would both pack more punch, and be reloadable--should you wish to learn to load cartridges yourself as a thrift/self-reliance measure.

    not exactly

    .22LR vs .22WMR
    .223 bullet dia .224 --delta--


    .225 neck dia .240
    .225 base dia .241
    .275 rim dia .291
    .040 rim thick .046


    overall not a good/safe idea

    Totally safe. As proven by the hundreds of thousands of "conversion cylinder" revolvers in use worldwide.

    As best I can determine, no such rifle exists, but even if one did, it would be perfectly safe. The non-jacketed bullets used in the .22 mag wouldn't cause any meaningful pressure issues. A .001 difference in diameter isn't going to create drama in a lead bullet.

    There is a reason no combo 22 rifles exist and it is safety. I've never seen a non-metal jacketed .22mag bullet.

    There are sets out there but expensive because the rounds are different in length and diameter and the rim is also different in diameter.
    If looking for a good rimfire I would go with a 22lr.

    If you have a .223 rifle, you could always entertain getting the subcaliber devices that will allow you to use the rimfire cartridges in the rifle. Sure, they make for real slow reloading BUT they do give you the multi-caliber option.

    Besides, cases are different as well.
