Cartridge power - reduced loads

Stu · 12-06-2002, 05:46 PM

Unspellable's explanation that the key factor is momentum, (mass x velocity), is pretty reasonable. I think when the topic generally comes up most people ignore the charge component for simplicity's sake, as it does complicate the equation somewhat !

So we should be able to come up with a rule of thumb in terms of momentum to give reliable functioning, I assume ?

I know some people out there have chronos, could we get some figures on the loads that work well, (9mm Winchester 115gr, anyone have the velocity ?).

I'll volunteer one set of info for the 30; Western X 93gr @ 1220 fps for 307 ft. lbs.
