Since these bullet didn't stabilize in my 1/30 twist Knight Disc Elite 45. I decided to try them in my 1/24 twist 50cal Savage with BH209. The first target is with a Harvester Blue crush rib sabot. This sabot loaded way to easy in my Savage.
The next group i switched to the Blue MMP and upped the powder a little. The Blue MMP loaded a bit firmer and i was more comfortable with the MMP sabot.
