I sent my 22 into H&R for a 22 magnum barrel the end of August. They received it on the 31st and shipped it back to me on the 14th of September! I mounted an old Tasco 4x 22 scope on the new barrel using the high Leupold Rifleman rings (great rings made in USA, in fact, even the allen wrench that was supplied is stamped made in the USA!).
Today, my 16 year old daughter and I went down the hill to the my shooting range. This was here second time out shooting with dad. We fired a few warm up groups with the 22 long rifle barrel - she did as well as I. Then we switched to the 22 mag. The first few shots missed the target at 50 yards (no big suprise), so we moved close to the target. I showed her how to adjust the scope, and we walked the shots to the center of the bull. Moving back to 50 yards, the shots were on the target, and quickly centered. My last 3 shot group was about 1/2". Ammo was Winchester Dynapoint.
She had a great time. I think I have a new shooting partner. I think we will try my H&R Model 158 357 magnum next. Not much recoil, but a bigger bang (and hole in the target).
I am going to get a 6-18 Bushnell Banner scope for the 22 magnum - Scruffy watch out!
