Should be a Taylor index value of about "30" at 100 yards which should be good up to elk size animals. If you look at just the ft/lbs, you would think it was just a marginal load even for deer. Interesting.

Looking at the ballistics charts on the Remington site seems to indicate that the 12 gauge is supierior to the 20 gauge. It looks to me that the bullet design has a lot to do with the good terminal performance you both have been getting. With a bullet that opens up and retains most of its weight, that should add some devestating results. I am curious if the industry will continue to improve the muzzy solids to include better controlled expansion. We will see.
