I've never used those two....I prefer the 300gr Hornady .430 XTP with a plain green Harvester sabot...My buddy likes the 240gr also in .430 diameter...
Many use the 300gr Hornady XTP .451 in a black .45 caliber sabot...Or the 250 gr Hornady XTP in that same sabot...
I'd send them back for one of the above..
