Ruger 10/22 : 17HM2 conversion?

Greetings,

I am considering a trade for a Ruger 10/22 with a 17HM2 conversion done and I know very little about this conversion other than it is a barrel and a bigger bolt and that the 17HM2 ammo shoots flatter for greater distance with more knockdown power and is about $10 per 50 rounds.

Can anyone add any personal experience/knowledge on this conversion and the ammo.

Opinions welcome...

    I have done a couple conversions, ammo becomes an order necessity. If you are willing to purchase large quantities online its about 6$ a box.

    To date the top 2 conversions I've done were a 16.5 inch green mountain sporter barrel with a heavy handle. The other is a Magnum research with the heavy hadle from skeeter. Both were light weight builds and shot very well. The magnum research rifle has inspired no less than 5 friends to do similar hm2 builds.

    They should come with a warning about how addictive they are, and with ammo like it is, its an expensive addiction.

    As for on game performance there is no 22lr that compares, and as a recovering rimfire junkie I can say that with confidence. Its the closest thing to 17hmr, and 22mag power in a standard 10-22. Bullets do wonders on whistle pigs and put grouse and ptarmigin down beautifully.

    Do you need to do any modifications to the action to allow proper functioning of the 17 m2 or does it just require a barrel swap?

    The general consensus is that a heavy handle is all that is needed. I did one with a 10-22mag spring and it seemed to work just fine. Some guys tried drilling the bolt and adding tungsten rods, but I can't imagine what it would take to put that big of holes in a hardened bolt.

    I can't off the top of my head remember the exact weight needed but it isnt much. I have shot a few boxes through an action with a rear reciever pin that was stuck without the heavy handle. However skeptical of the heavy handle in the begining, after that it was fairly convincing. 1 box and the pin slid right out, and I wasn't able to pound it out wiht a punch prior to that.

    My magnum research rig has 1000+ rounds with no problem, the green mountain probably only 500. A buddy has one of the shaw heavy handles and tubes and I'm pretty sure he does well over 2000 rounds a year shooting whistle pigs and its held up just fine.

    Thank you for your feedback

    I will have to look up Green Mountain, Magnum Research and Skeeter. This particular gun's barrel is stamped "E. Arthur Brown Company" and I suspect this is the kit that was used, before it was discontinued http://www.eabco.com/hornady17hm2.html

    your feedback sounds promising in regard to the rounds' capability. I found Hornady rounds for it through a local outfit for $6.09 for 50 rounds.

    Green mountain Is a custom build, they didn't want the liability of the 17's. Mine was built with a 96/17 barrel. The eabco was one of the origional conversion kits, I'ts pretty good. 6.09$ is a great price for hornady ammo, boy I wish thats what they were here.
