    22lr. To 22 wrm

    On a winchester 1885. Can a 22LR be reamed to 22 WRM.
    22LR Barrel .223
    22WRM. .224

    Would the barrel diameter cause any pressure
    Problems.

    Guns that shoot both calibers such as Ruger single six use .224 bores.
    22lr and 22wmr have the same pressure interestingly enough.
    It was common to do this conversion years ago.
    1885’s are darn nice guns. If it is original I would leave it alone.

    I don't have any real answers to your question so here is what I know. Ruger and Colt made revolver convertibles that with different cylinders, could shoot either. So I think the question of pressure is not a problem. Whether they used a 0.224" barrel to make sure it was in all cases safe I do not know. I bet Mr Harris can tell you.

    The level of accuracy might not be as good as the correct size barrel, who knows? Also, a reamer with a changeable pilot would be my choice. A fixed pilot may or may not fit the 0.223" barrel.

    Congratulations on owning an 1885 Winchester. I would suggest that modifying your existing rifle would cause it to lose more value than a new modest single shot rifle in one of those calibers would cost. If it is an original 1885...manufactured a hundred or more years ago, it would be a great shame to modify it... In my opinion.

    I dont own it. I was trying to haggle on it at a sporting goods shop and the owner is probably going to keep it and ream to Mag.
    Its a later model made I think 2005. They only made 2500. Half octagon half round barrel.
    I was thinking if I convinced him the barrel dia would not work he might go ahead and sell it to me. Fingers crossed.

    The Colt Scouts with dual cylinders had issues with their .22LR barrels. They did indeed have pressure issues and Colt changed in 1966 to use the larger .22 Magnum bore. I just sold a 1966 Colt Frontier Scout with both cylinders, and like new condition. Inside the box was a note from Colt saying "this gun is equipped with the larger bore to shoot both .22LR and .22 Magnum safely. Do not shoot earlier guns with the smaller bores. Send them back to Colt to be refitted to the correct bore size."
    So Colt must have had a recall on these guns from what the note said in the one I had.

    And the twist rate is always an issue with guns shooting both bullets. They rarely shoot both accurately, and usually have the correct twist for the .22LR, which gave the .22 Magnum a reputation for poor accuracy.

    I currently own an 1885 that had an eroded barrel, was sleeved to 22lr (223?), then reamed to 22 magnum. It shoots quite well and has had thousands of 22 mag rounds through it, no problem. I also have a friend who had a Martini 12/15 reamed to 22 magnum (tried to talk him out of it, nice original rifle), it shoots very well and really makes a nice 22 mag. I've probably seen/shot a dozen 22lr rifles reamed to 22 magnum, I've never seen a problem.

    Results vary, I'm sure, but I recall a thread here where a member pulled .22LR and reassembled them with .22WRM projectiles he pulled, and it seemed fine until he realized he'd shot the rifling out of it.
    Show the guy that thread and the price of a new barrel, he might change his mind.

    Also 22WMR are jacketed bullets...that will cause more wear also. Speaking of which. Many of those old 22 rim fires were permanently leaded up and that helped keep them from wearing out.

    Just because there is a specification does not mean the barrel will be exactly .223. I would bet it will be a little ovesize like most other factory barrels. For example every one knows a .375 Win is designed for .375 bullets. My .375 Marlin checks at .3778....

    I have a Colt New Frontier 22 lr/22 WMR that I bought new in 1975 and have shot regularly ever since, it is my favorite revolver by a wide margin. This gun has the .224 bore and shoots both 22 lr and 22 mag quite well but is noticeably more accurate with 22 lr which is kind of curious given the over-size bore for that round.

    Now about the OP's question, the one (only) 22 lr to 22 mag conversion I am personally familiar with is/was an older Remington 22 bolt action single shot that a co-worker re-chambered some years back, accuracy was poor and it did indeed show signs of excessive pressure. So much so that the rifle was retired and now considered unsafe to shoot, he probably still has this rifle since it belonged to his grandfather but the last I talked with him about it a few years back he very much regretted the conversion.
    Statistics show that criminals commit fewer crimes after they have been shot

    It's not a real 1885 Low Wall, it's a modern reproduction.

    "It’s a later model made I think 2005. They only made 2500. Half octagon half round barrel."

    It would work just fine, although you can buy a brand new one in 22 magnum.
