i have been ML hunting these last 2 weeks. i shot a 6 point last week and my dad shot a 6 point the week before. we both had the same results with powerbelt bullets. the bullets put the deer down but did not stay together and expand like they should, instead they exploded and fragmented throughout the vital area. we could not find any piece of his or my bullet when cleaning the deer (there was no exit holes). his deer was shot at 15 yards using 150 grains of pyrodex and mine was shot at 67 yards with 150 grains of pyrodex. has anyone else experienced this? i like using powerbelts because of their accuracy, ease of loading and simplicity.
