Do tell where you are getting your GP11 from? I spoke to the RUAG rep at the Shooting show about getting hold of some of the new surplus GP11 made last year - about 20,000,000 rounds of it, as mentioned in the Swiss shooting journal.
a. He knew nothing about that, in spite of the fact that it is made by RUAG-Ammotech in Switzerland, but promised me that he'd look into it.
b. A couple of weeks later, a lady press officer wrote me, advising me that RUAG-Ammotech did not make any such ammunition.
Sigh...

PS - I'd be obliged if you'd PM me with details of your home-loads. TIA
