Good info Mike, how do you know this info, what is your source or did you inspect the bullets and sabots, I am not disputing your post, but would like to know your source.

Of all the things affecting accuracy, sabot I feel is most important. Too tight a sabot makes loading difficult or impossible, too loose a sabot causes "blow by" and no gas seal making for accuracy loss. So "Bullet Review" for accuracy, must include sabot, however bullet review for "killing power" or Terminal Performance as it is called technically or 'Boom Flop' assome say it on this forum is what we are all looking for, a bullet that is accuract as all get out and goes boom flop. I believe this bullet must be:
#1 accurate, because if your shooting 6" or 8" groups how can you be sureyou will hit the deer where your aiming
#2 penetration, becuase penetration gets into the vitals and does not blow up on the ribs or 1" into the deer causing a wound and not a kill
#3 expansion, since itis wound chanel and massive bleeding and tissue disruption that causes the FLOP
#4 shoot thru, cause sometime even with a heart hit or a double lung, deer sometimes run for a long distance and without a shoot thru tracking is difficult
#5 reasonable cost, so we can practice with them to get better

There are what I am looking for in a bullet. Some will dispute this list ofattributes they want from a bullet. Hope this help River Rat, in your Bullet Review.
