Takes some getting used to. - Thompson Center T/CR22 10-Round Magazine

I'm ordering a couple more of these for my Thompson Center T/CR22 rifle.
The magazine that came with the rifle was extremely difficult to use. The hold/open+first round lever was almost impossible to push down.
I gave up and used some 10/22 magazines which were much easier to load. Fuguring the problem was spring pressure I adjusted the Thompson magazine from the recommended three turns on the spring down to two. It worked better but was still a little difficult so I went down another half turn, trying to match the feel of loading with the 10/22s. Well now it works great. The loading lever is pretty easy to depress, the magazine is much easier to load and feeds perfectly. The last round hold open feature is a welcome addition. Point is... don't be afraid to loosen the spring a bit. You'll know if you've gone too far because it will stop feeding as well.
