That's an awful light load Doc, wouldn't come near making Major. Especially if a 13 lb. spring handles it okay. IDPA must be going the way of IPSC and the rest.

The CDP power floor is 165,000
For a 230 grain bullet, that would make the minimum velocity 717.4 fps - I'm running in the 720 fps range. with no signs of excess recoil. (cases don 't go far) Now here's the question: Do I actually have the 13 pound spring on there, or did I take it off when I ran out of 200 grain bullets (original reason for the 13 pound spring)...  I'll have to double check that. It could possibly be a 16 pound spring. Whatever spring is on there is good though... Last edited by DrHenley; 06-14-2011 at 07:46 PM.

BUT...I was looking at the USPSA rules this morning, and in the rule book I found online, Major Power Factor is listed as 165. The latest rule book I could find was dated 2008, so I don't know if that is still valid...But... You get USPSA Power Factor by multiplying bullet weight in grains times velocity in fps then dividing by 1000 right? 230x720/1000=165.6 (which is more than 165 by my calculations  )
