648 mag cylinder in a 617

[papax4]

I'm thinking of buying a 22 Mag cylinder for a 648 to install in my model 617. Couldn't find any posts discussing this. My 617 is a 10 shot, and hope an 8 shot model 648 will work with a little fitting. Before I blow $150 on a 22 mag cylinder, thought I'd ask if anyone has done this already, and how it worked. Thanx!

Should work, but I can't speak with any authority. Some people will mention that 22 WMR has a thou or two larger diameter bullet than the 22 LR, but most people say this is insignificant.

I fitted a 648 cylinder to a 617 no dash. Shoots the same POI with 22 lr or 22 mag. Each cylinder has 6 holes.
