I can't really say why, but I used to turn my nose up a little regarding PPU ammo. Perhaps in some caliber I had poor results in the past. At that time, I wondered why some had a relatively high opinion of PPU. Now I know...
Below pic shows a comparison of .308 match ammo in my recently completed M1. Criterion barrel, iron sights prone w/ sling at 100 yards. Ammo tested was Black Hills 168 BT HP Match, PPU 168 HP BT Match, and Hornady 155 ELD Match.
PPU was best of the bunch, with a really tight group of 4 and the 5th not far away. Good enough to get a fantastic score in a CMP match. The Hornady was pretty good too. Interesting that the Black Hills was all over the place- 4 rounds barely in the black and one round was barely off the paper (where I tore a notch at left). I thought Black Hills was supposed to be pretty good. Certainly this rifle doesn't like it.
Though groups are getting better since I reconditioned the bore on my K31, with GP11 I was getting hits all over the black and into the 8-ring on the SR-1 target. Popped in some PPU 7.5 Swiss and the groups tightened up, with all hits in the black.
Added bonus is the brass holds up well.
