After my last sighting in debacle, I went back to square one.
Fresh box of pyrodex pellets, 300gr hornady xtp and a harvester crush rib sabot.
2" group and right on the money! I even found one of the 300gr xtps in the dirt when picking up the target. Amazing expansion and great weight retention. The jacket petals had folded completely around the base and the bullet expanded to about the size of a quarter. I was a little worried about the Non-mag XTP version holding up at MZ velocity but it did great.
Lawwwwd help the deer that gets in my sights this weekend!
