I was thinkining of using a Gemtech, but:
1) They don't list a 10mm threaded barrel
2) I use double tap mammo mostly and worried about over pressurizing a can made for .40 S$W cartridge
3) Would it cycle reliably by tuning the recoil spring rate? Even with a 6" hunting barrel?

Call Gemtech for an authoritative answer on the first two questions.

Generally any can with a LID/piston/booster will cycle just fine without spring tuning.
