I don't know if my information is what you are looking
for. But I shoot APP but in stick form, rem. kleenbores,
50cal Omega. I have shot the PB'S with up to 150gr.
charge, groups were all over the place. So I tried the
Hornady 300gr. XTP-Mag HP they shoot really well in
my Omega. My normal charge is 100gr. but I still get
good accuracy even at 150gr. The only ML I own that
shoots PB'S very well is my 45cal Beartooth.
