[I moved this post to the revolver forum. Sorry for any inconvenience. Joe] Hi all, new member Joe here with few questions on converting my 22 VH6 to a dedicated 22 magnum. I'm still in the planning stages and plans change so, if something in my plan doesn't sound right, PLEASE correct me! I have been in e-mail contact with EWK inquiring about parts and service abilities on this project. My plan at this point is I provide them with a 22 mag barrel blank, (Green Mountains PR22M), they will turn it for my frame and I will use my existing shroud. They suggested I ream the cylinder myself. First, is it safe to assume the 22lr cylinder is long and strong enough for the 22 mag. (I read somewhere that SAAMI pressures are the same). I'm up for the challenge and looked into reamers and have questions concerning this process. Should I use a floating or solid pilot reamer? Do I ream the entire length of the cylinder? Is it smarter to rent a reamer or should I buy and maybe resell it later? Is there anything else I need to know? Thanks in advance! Joe
Joe- I moved this and deleted your duplicate post. Regards- Ron

Here's my suggestion.....send the gun up to Norwich and have them fit a new cylinder to your frame and keep your original cylinder. You don't need a new barrel - save the money and put it into the new cylinder.

+1 to what harly said.

So, harly and SCORPIO are you saying it's safe to use my .222 diameter 22lr barrel with 22mag ammo? My understanding is the 22mag bore diameter is .224. Joe

It should not be a problem, the only possible issue would be in chamber pressure. Keep in mind that you are shooting .22 lr/.22 mag in a cylinder and gun designed for .357 mag, and one of the strongest .357's you will find.
Best of all worlds would be to have a second cylinder made and timed for your gun, and be able to switch back and forth pretty easily.
I went to a bookstore and asked the saleswoman "Were is the Self Help Section?" She said if she told me, it would defeat the purpose.

Exactly what SteveCT said. The Dan Wesson 22/22mag is the same frame and cylinder they used on all the small frame guns up to and including 357magnum. There is no way a 22mag is going to be too powerful for that cylinder. Look how much more 'meat' is left in the 22 cylinder compared to the same cylinder bored for 357. Get that second cylinder timed to your gun and you will be able to swap calibers easily.

I once had a Ruger revolver with 2 factory supplied cylinders - .22LR & magnum. Don't know the bore dimensions but it happily shot both.

From the research I have done, Ruger single sixes are bored .224. Many articles and posts that I have read online claim that the 22 mag cylinder in a Ruger is more accurate. Personally, I can attest to that. My mag cylinder shoots better than the long rifle cylinder.
I just sent my DW 22 to Norwich for a 22 mag conversion. I had the same question about the .222 bore. The gunsmith said it would be fine and I have confidence because that bullet is only being swedged .002. My father told me a story from his IHMSA days back in the day when he got confused. He had a 3030 tc contender for big bore and a 357 mag barrel. He dropped the 357 in the 3030 and shot. The cast bullet came out.
Anyway, I am getting a new ejector rod, extractor star, and an unfluted cylinder. The total was $297.95. Much cheaper and less time waiting on a DW 22 mag to come up for sale. I also considered a Smitty 648, but those are every bit of a grand these days on GB.

I think this is a great option, and that is a great price for a "switch caliber" rimfire.

If you're concerned about the .002", then shoot gas-checked cast bullets; 'viola, no more issue. All of my cast bullets are .002-.003" over groove diameter in order to get a good seal and prevent leading.
