A couple of years ago, I bought a Norinco copy of a German .22 Mauser Training Rifle from a guy walking around a gun show, paid $150 for it with a spare magazine. Looks just like a German Mauser, even has the metal hole in the stock and cleaning rod under the barrel. I had never seen one before, found out that is because Bill Clinton got mad at the Chinese for some reason and quit letting them import Norinco products. Canadians can buy them, I think they are around $275 Canadian. Here's a pic:
Photo of the military Mauser type sights, marked out to 200 meters, but in reality you run out of elevation at 100 yards:
When I got the rifle, the front sight was puposefully too tall, you had to file the front sight down to regulate the sights. I set the rear sight at 25 yards, then filed the front sight a little at a time until it was hitting point of impact, point of aim. The I tested it at 50,75 and 100 yards, sights were set perfectly! If you want to make a head shot on a man sized paper target at 100 yards, slide the sight to "100" squeeze the trigger and you have one dead paper dude, with head shot! I did a lot of shooting and note taking about how to set the sights for a particular shot, for instance, if I want to use a 6" o-clock hold on a 50 yard target, the sight is slid to the 75 yard position, then all shots slay the black at 50 yards. All of this data was recorded and laminated to the stock.
At shorter ranges, empty shotgun shells at 25 yards are no challenge, at 50 yards clay pigeons are doomed. Here's a group I shot at the range Saturday, 50 yards, prone, unsupported:
The reason I share this with you is to reccomend if you see one used somewhere, buy it! They also made a sporter version of the rifle, if you don't like the military look. I heard somewhere the actions are copies of CZ's, and CZ magazines will work in these rifles. In this day of expensive rifle ammuniton, a fun and accurate .22 can fill the void in your rifle training!
