anybody heard of this??, how do you thing it would do on penetration for say groundhogs or maybe even coyotes, I know it would leave tiny hole, but I would imagine on a coyote the expanding bullets wouldn't get much deeper than the first shoulder blade are on a chest shot, I would think this would possibly zip right through the whole thing??

The 20 grn rounds were designed for a bit larger game and better penitration. They originally just had 17 grn hollow points and V-max bullets from 4 manufactures, but really only two different bullets, one a hornady and the other a CCI TNT. The other two companies just put their name on it.

Then 17 owners started showing an interest in a heavier better penitrating bullet for large ground hog, fox and small coyotes. So the ammo makers stepped up and gave us what we wanted. A 20 grn XTP controled expansion bullet. I haven't used them, but many on Rimfirecentral have and seem to like them on slightly larger critters where you would want more penitration instead of voilent expansion.

Velocities are still pretty good as well.

OH, I just noticed you were talking about the FMJ rounds. They would most likely penitrate even farther. My opinion would be to go with the 20 grn hollow points for hunting.
