That's kind of an interesting idea. I never thought of using sabots in a 10mm. Keep us posted on how this works out.
Will the 10mm not handle prairie dogs at 100+ yards? I shoot 100 yard targets all the time with both my 10mm pistols. I've never hunted prairie dogs so I don't fully understand the advantage of the saboted 224 over a standard 10mm.
