The bore diameter on a .22LR and a .22 Mag are different.  At best it would be a compromise.  At worst it could be dangerous.  I wouldn't do it, especially if it is a good enough LR to want to spend the money on rechambering.  My bet is you wouldn't like the outcome.

Besides the bore difference, you'd have to deal with magazine length and/or feeding. If you're dealling with a single shot, you'd be better off just buying a new 22mag rifle, they aren't that expensive, not much over $100 new, a rechamber will cost half that.

In guns that allow firing of both rounds such as the Ruger revolvers the bore diameter is 224 as is used for the22 magnum round. The lead bullet from the 22 long rifle is allowed to bump up from the pressure. This does not lead to stellar accuracy.

What gun, for starters??? Re: rechambering

You can do about anything. Is it safe? Is it wise? Maybe not.
#1). How strong is the gun? Many old .22 rimfires were built around 20K CUP pressures or less. .22 Mag works in the range of 35K CUP. At best, the gun would "work lose." At worst, it would blow in your face and if you are lucky, you DIE!. [WHITE CANE time...] Today's versions of the same model are newer steel or better heat treat or ??? and safe that way.
#2). .22 Long Rifle uses a lead bullet at .222. .22 Rimfire Mag uses a .224 bullet. Is this going to blow the gun up. Probably not. Will it improve accuracy. Probably not.
#3).  Cost. A cheap, quick rechamber might go $50.00 unless you have a friend... Maybe more. Top flite work, a lot more.  A new gun would be about twice that. A used gun? Shop around.
Can you. YES. Should you? Probably not. LUCK.

The SAAMI MAP for the 22 mag is 24kpsi, same as the 22Lr. ;)

pressures...
« Reply #6 on: May 07, 2007, 05:42:13 AM »
Mr. Quicktdoo makes a good point. These are, as listed, average "maximum" pressures. What I have gone by in the past, CCI did an advertisement many years ago for their Mag ammo showing a "belt" internally and implying that the pressure of the average Mag was alot more than the average .22 L.R. The other point I forgot entirely, .22 Mag is a lot longer than the .22 L.R. You have enough action length? Many would Some not. AND many L.R. barrels for lead bullets were not the sturdiest steel. Plenty for the lead bullet, but for a jacketed bullet??? I have known gunssmiths who claim to have seen more than one "micro groove" shot out. Then there is the discussion of the additional wear High velocity ammo puts into the gun over standard velocity... I would not spend MY money on this project, but it is not my project... THANK YOU... luck.
