17MH2 and 17HMR on Ruger 10/22 Receiver

[Scotter]

I just built but haven't shot it yet a 17Mach2 on a Ruger 10/22 receiver. I got a call from a friend that said heard Ruger was reporting some receiver problems with the 17 cal. I'm thinking it has to be the 17HMR and not the 17Mach2/17MH2. I can't find mention of any problems by Ruger anywhere on the net. Does anyone know or heard about this too?
I love building the target guns and I do love the Ruger 10/22.
Thanks, any and all comments appreciated...

Go here for everything you ever wanted to know about rimfires in general and the 10/22 in particular.

I know a couple of guys that have tried to convert 22mag to 17HMR, and 22lr to 17M2, they both had serious cycling problems. I asked one of my instructors abut it, and he said it has to do with the bullet weight. The very light 17 bullets don't create enough backpressure to properly cycle the action.

I did use a Volquartsen bolt with heavy recoil spring. Of course the bolt, recoil spring, firing pin, ejector are all Volquartsen and specifically for 17HM2. I also used Volquartsen barrel. I really think I've covered it my only real concern is the notice by Ruger with the receiver problems.

Thanks, I'll check out Rimfirecentral.....

You use a ruger 10/22 receiver for a 17HMR-M2 conversion. General consensus is a heavier bolt handle must be used. Some were experimenting with attempting to make the bolt heavier or stronger springs. Magnum research sold a heavy bolt along with a barrel for their conversion kits. All other conversions I've seen, went with the Heavy bolt handle theory.

For a 17HMR a 10/22 Magnum receiver must be used.

I've converted a 10/22 to 17HMR-M2 and been very pleased with the results.

The problem wit hthe .22 lr to .17 HM2 conversion for the 10/22 is the higher bolt velocity generated by the .17 HM2 on the stock 10/22 bolt and recoil spring. Couple this with the aluminum receiver and the failures will eventually show up. Adding weight to the bolt and/or bolt handle and adding a stiffer spring along with a bolt buffer fixes things for the most part.

For the 10/22M conversion to .17 HMR, the steel receiver is much more durable. They can be made to be as reliable as a regular .22 lr 10/22 after it has been broken in. (The 10/22M in stock .22 mag form also had the same problems as the .17 HMR conversion.)
