Ejection on my rifle (Anschutz 64 MPR)was very poor, 1/3 of the cases exit properly on the right, 1/3 out the left side, and 1/3 just lay on top of the next shell, regardless of how fast or slow you work the bolt. This seems to be a common problem on this model, and is totally inexcusable on a $1000 rifle, my old $39 Stevens single shot worked better.
I have been studying the problem for several weeks, and had confined my work to the "shell retainer" (the left side extractor looking thing) as I had thought the problem was this part was holding the case too securely, as several people on rimfire central.com have removed this trying to get these guns to eject better. I ordered a couple of spares and whittled them into several different configurations to no avail.
I started studying different brands of bolt action .22's, I had an old Remington and a Ruger 77/22, and looked at several others at some gun shops. My brother-in-laws Savage MKII was what really turned on the light, as it is a close copy of the Annie 64 and it works perfect.
The Annie 64 extractor holds the head of the shell very tightly against the bolt face, all the others, without exception, had at least 5-10 thousandths of "slop" between the tip of the extractor and the case rim.....BINGO!!
An easy fix....
Disassemble the bolt, carefully pry the half round leaf spring off the extractor or shell retainer with a small screwdriver.
Here are the parts, the shell retainer is on the left side and the extractor is on the right side, don't get them mixed up....
The extractor (on the RIGHT side, with the sharp hook) needs a small amount removed from the small flat marked with the arrow. This allows the hook to be farther away from the bolt face when extracting.
Do this a little at a time with a small file, reassemble and check ejection after each few thousandths, keep the angle at 90 degrees, don't angle it out. I removed about .012 inch from mine.
The half moon spring is kind of a PITA to snap back over the ejector and retainer, it helps to clamp the bolt in a vise facing up, and use a thin wire or jewelers screwdriver to make a ramp and slide the spring down over the part, make sure the hooks are completely snapped over both sides.
Mine works perfect now, I can work the bolt fast or slow, it doesn't matter, piles them up right beside me.
As always, this worked perfect on my gun but YMMV. If something happens and you screw it up, a new one costs about $9 from Gunsmithing, Inc.
Hopes this helps someone else.
