Questions about 10/22 WMR/17 HMR

I got a deal today on a Ruger 10/22 magnum, NIB for $200.00. I couldn't believe it. I am going to put the 17 HMR barrel and polymer stock that I have on it. Do I have to make any other mods or changes to the 10/22 WMR receiver to accomodate this caliber? I also would like some suggestions on optics for this weapon. Thanks, DRJEW.

BTW Great deal.
No, you do not have to make any other mods or changes doing this conversion - that is unless you want to do some enhancements.
I converted a Ruger 10/22 Magnum into a 17HMR several years ago after the 17HMRs came out but before the gun companies came out with their models. I used a Jarvis target barrel with factory contour to keep the original wood stock.
Although it is not necessary when converting to the 17HMR a drop in trigger, extra power extractor, and recoil buffer will certainly enhance performance of your new rifle. An after-market drop-in trigger can lower the pull down to about 2 pounds which will also help increase accuracy. Since the rifle is being converted from a straight wall case to a bottleneck case and a tighter fitting chamber, the extra power extractor helps in ejecting the fired case. A recoil buffer helps to reduce recoil impulse on the bolt carrier.
A variable 3x9 scope is a good option for the this round.
Hope this helps.

I think an extra power recoil spring is a great idea.
The Ruger 10/22 Magnum to 17HMR does not have the prerequisite for a high mass bolt handle as does the Ruger 10/22 to 17HM2 conversion.
Ruger 10/22 22LR can only be converted to the HM2. Because of the higher pressures, the original bolt carrier does not have enough mass to keep the breach closed long enough. Most after-market conversion barrel manufacturers recommend a high-mass bolt handle to resolve this issue with the Ruger 22LR conversion to 17HM2.
This is not the case for the Ruger 10/22 Magnum conversion to 17HMR. The Ruger 10/22 has a receiver made from steel compared an aluminum receiver on the Ruger 10/22 22 LR. The bolt carrier is also heavier and can withstand the 17HMR pressures. Receiver pins can also bent by the 22 Magnum.

Have fun!
