For general plinking ammo that will not cause excessive wear to the model 41, I like the Federal 550 paks that WalMart sells. It functions fine, very few FTF's, and it is loaded a little lighter than some of the other bulk pak shells.
Here are some specs:

Rem GB's 550 value pak: 36gr HP @ 1280 fps
Win 333 ct value paks: 36gr HP @ 1280 fps
Fed 550 value pak,
load # 750: 36gr HP @ 1260 fps

Of the three, the Rem is the "hottest" sounding, and has the snappiest recoil, followed by the Win 333's (which are about the same as Super X 40gr), and then the Federal is the mildest, both noise and recoil wise.
The Federal would not be my first choice for hunting, but it is an excellent plinking round, and works well in my mod 17 revolver and all my pistols, S&W 41, Ruger 22/45, S&W 2206, S&W 2214.
The Federal also has the fewest FTF's.
