I read my Hellcat manual and I didn't see a mention of +P loads.
So... I assume that means that this is rated only for normal P loads?
		
		
	 
As side notes to keep in mind: You may void your factory warranty if using re-manufactured or reloaded ammunition.
Per Owners Manual:
"WHAT IS NOT COVERED BY THIS LIMITED WARRANTY?This  Limited  Warranty  does  not  cover  any  damage  or  condition  determined  by  Spring-field to be caused by: unauthorized repairs, disassembly, adjustments or modifications, carelessness,  negligence,  misuse,  or  unsafe  handling,  normal  wear  and  tear,  failure  to  properly  or  reasonably  store,  use,  or  maintain  the  product,  hand-loaded,  reloaded,  re-manufactured, or defective ammunition."
Also, keep in mind if using higher rated ammunition than what's specified by manufacturer may put more stress on fire arm.  But, going by above info posted earlier am not thinking that's a huge concern.
A good helpful article that may help you to understand some differences:
