Many aftermarket bolt manufacturer's package their bolts with different power springs... I have most of them, including a number of Tony Kidd's, VQ's, RT's etc... The power springs are so that you can tune for specific ammo's at a given energy level... If the spring is light and marked ".22 short" (I have not seen that designation in Kidd's literature with their aftermarket bolts) I can guaranty that it will NOT function in a 10/22 with short ammo... There is more involved to making a semi function with shorts than just changing the spring... Some have been mentioned above, namely magazine function, bolt weight and rebound rate which is also a function of action system friction (not just weight and spring tension)... A few years ago I did a shorts project gun and had it up and running perfectly with the VQ shorts kit and modified mags, but it was a lot of work and tinkering to get it working properly... I sold the gun and now just shoot semi's in dedicated subsonic guns in "bench" configurations and HV guns in speed/plinking/hunting configurations. I do also shoot bolt actions and have one gun set-up for CCI Quiet's. In my opinion there is little advantage to shooting shorts in semi guns when there are so many options now in low-energy long and long rifle loads. But to answer the OP's original question, "yes" you can safely shoot shorts in your LR chamber.
