Poster Loggy on another site just reported fantastic groups with 348 AT Powerbelts. Buy both pellet-packs, the 50s & 30 grainers. That way you can tweak your powder load better i.e.. 80 - 90 - 100 - 110 -120 if necessary. Another bullet to consider is the T/C Shockwaves in 250 or 300 grains. If your budget is tight, buy a 50-pk of Hornady .452 cal 300 grainers for around $10 in the centerfire reloading section of gun stores -- then buy a 50-pk of MMP 50/.450-.452 plastic sabots for around $6.95. I heard good reports on the T' Cs & Hornadys also.
