Hey brother German (2005) it has been too long for you out of the mix. Come back in.I shot a .22 PPC with 80's for a long time, great combination. I used a 1:8" twist barrel, mostly Berger 80 VLD, but also tried some 75 Berger and 80 Sierra. Best powder was RL15. I even wrote a piece about it, click here: http://www.6mmbr.com/gunweek067.html
