went to the range with my TC white mountian....1-20 twist(maybe28) I wanted to see what it would do with saboted bullets I've only shot maxi hunters for over 20 years and some rb's this year...r.e.a.l's too...but because of the twist rate I probly been useing the wrong ammo I've allways hunted with 90 grs rs pyrodex so I started with that 90 grs rs with a 50 cal harvester crushed rib sabot and a xtp mag 300gr .452....first shot was me high left (out side 1 shot of day)but 2 good shoots and 2 poor shots followed all shots were at 50 yards
