A while back, I got a Mk II BTVS. Pretty good rifle though the barrel wasn't freefloated like it was intended to be - so I fixed it.
After making Rifleman at Appleseed with a 10/22, I broke out the Mk II for some fun. I didn't have any extra mags, so I was loaned some 10 round mags, and dang near shot a perfect score - with a bolt gun yet!
After the Appleseed shoot, I went to buy my own magazines. Imagine my disappointment when the new magazines were junk. Only my 5 round mag works correctly.
I have a background in combat handgunning, and I find this unacceptable.
So, I took the 10 round magazines apart.
Imagine my surprise when I discovered that they are just a downsized, curved (for the rims) version of the 1911 magazine!
I checked the feeding, and sure enough, it's a controlled feed, just like the 1911 pistol.
Better yet, the magazine springs are modeled after the 1911 magazine springs.
I tweaked a few things and got better reliability out of them, but still not 100%. This occurs in 1911 pistols as well when you go with a larger-than-normal magazine size. Just the nature of the beast.
However, these should still work. The follower is a poor design but can be tweaked. What's really needed are good springs - these are by far the worst springs I've seen in a stock magazine. They are almost like Bic pen springs in quality!
Stretching them and giving them a lil' twist upward work for one or two mag fulls - then the spring settles back to its stock length.
What we really need is a good quality, heavy duty spring.
I'm sure Wolff makes something like this. If not, they need to. I need your collective help to find a heavier duty spring. It would look like a 1911 spring and likely be in either a conversion kit for the 1911 or in a Ruger .22 autopistol - I'm guessing. I'm also thinking that Llama made some smaller Government-type model pistols in .22 - these may work.
I've never owned an automatic .22 as I'm a lefty and they just now started making them. However, if you happen to have a magazine for, say, a .22/45 laying around and want to compare springs, it would be appreciated.
Mostly though, the magazines are junk. And that sucks because the rifles are very nice. Skimping on the magazine though will almost always kill reliability.
If we make enough noise, I'm sure somebody - perhaps even Mec-Gar - would pick up manufacture of aftermarket mags which are not sub-par quality.
Just some random thoughts... and I got another idea for a mag, so I'm gonna go try it out.
I have been trying to tune mine in for awhile. The first four rounds feed fine and the fifth hits the bottom of the chamber and puts a ding in the bullet, not an issue for plinking or small game use, but the rifle is a completely custom rifle I am using for bench work, so that ding is super bad.
Joshua M Smith gave me an idea, I have a couple of older Savage 23AA/19NRA mags that work very well. I pulled the springs out and noticed that the 23AA spring were a touch shorter but stiffer than the MK2 spring. Swapped the spring into the MK2 and a touch of adjustment of the feed lips and no more dings.
I wonder if we can get our hands on some Anschutz springs and followers.
I solved my magazine problems. I traded my MKII for a MKI. Also went from plastic stock to wood.
I had just as bad feeding issues with the mk1. I found that unless the bullet was put in just right it would get caught on top of the single shot adapter and jam the bolt. That piece of plastic they use for the feed ramp is a joke.
My mags are all somewhat older. Maybe they have switched to less capable springs. That would be too bad. It's always a downward spiral to cut costs on a working platform until it builds a bad reputation.
Joshua Smith ( and doublechaz)... I have taken up your challenge ( although I'm coming in VERY late on this thread !!)...
...you want to find stout magazine springs to try out.
Well....the Ruger autopistol that you suggest won't work because they use a coil spring ( as many other rimfire mags use) placed in the very front of the mag. You want a coil spring that is wound square/oblong, like the Colt .45 magazine spring. Precious few guns do it this way.
Tonite I dug deep into the Numrich arms catalogue, alongside the Hoosier Arms catalogue to find something to try. Here it is--->
Smith and Wesson M22A/M22s mag, rather recent production, 10 shot. Here is the picture---> http://www.hoosiergunworks.com/images/sw_22a.jpg Notice the style of mag spring that we want, somewhat square-wound to fit the inside dimensions of a 22LR mag housing.
And from the Numrich catalogue, the mag spring is part number #185840 ... cost is $6.75 plus shipping. Since shipping may cost a lot, may want to order maybe 4 right away, even as a test.---->
Scroll down the schematic page to part reference 21...there it is.
Since this was made for a 10 rd mag, it may work for the 10 rd Savage "as-is", and it may need to be cut-down some for the 5 rd mag. But be advised, I've been on such a path before. As long as the follower has enough length of its "legs" below the follower itself to avoid full spring compression after loading 5 ( in the 5 rd mag) .... you may just as well use the full length spring, at least as a first test.
Good luck,....let me know how it goes, as I am looking to buy a MKII myself. Success here will sway me toward the MKII instead of going to a Marlin XT-22.

IPSC-- new to this part of RFC forum as I just purchased Mall TV with fluted bull barrel. The accuracy is unbelievable and I had thought my slightly modded 10/22TD's were accurate. So, the problem with the ten round mags persists? No way to buy a good functioning ten rounder? The supplied five round mag works well but would like to have a ten round or two. Rick
