I have loaded for one not your typical K31 mine has a 1:13" Tru elite barrel I shoot Sierra 155 PALMA in it, Your groove diameter is .306" and bore is .297"
so take care working up loads the Sierra 175 MK is a good match or the 175 VLD Berger, Rumor has it that RL17 is what is loaded in the GP11

Good luck
Robert.
