So if I'm understanding what your saying I could purchase the Marlin 7rd mag and switch the base plate from one of my 5rd Savage mags and it will work? Is that right?
I could have swore I found a site last night that said 22 magnum or 17 HMR 10 round mag but, now I can't find anything but the 22LR and the Mach2, like you mention. This brings up another question, not that I would do this but does anyone know if you can shoot a 17 Mach2 round out of a 93 series 17 HMR Savage? I believe the only difference is it's a shorter round so, I would think it would be similar to a 357 and a 38 which you can swap out. Anyone ever try it out. If I recall the Mach2 round is around 2000fps so,it doesn't seem like a bad round.
