Just got myAmerican Hunter, there is a story about a caribou hunt. He use a 130 grain Barnes bullet loaded by Federal in the Premium line. The "first bullet hit the caribou bull a little high. It took out 6 inchs of spine and turned the top of the lungs to jelly" The second round, really unneeded hit a frontal shot the bulle was just under the hide on the his butt, nearly 100% weight retention.
There have been numerous reports of hunters using a very fast Barnes solid like this .30 caliber 130 grain. They do as reported: retain weight, and penetrate like crazy. You're into Chevy/Ford territory after that. Some will report "bullet failure" where the bullet failed to completely expand, or tumbled, or lost a petal, etc. That is offset by the 99 other hunters who rave about the bullet.If you like the ballistics of the fast bullet, by all means try it out. As has been noted, at very long distances the ballistic coefficient of the heavier bullets allows them to close the ballistic gap somewhat.If you put a .30 caliber 130 grain Barnes TSX or TTSX bullet into the vitals of most any North American big game animal, it will be game over very soon. Bullet placement is the most important variable.
I think the notion of shooting a light bullet for the cal is a little gimicky. If you want to shot a light bullet drop down a cal. Shoot a 140 out of a 7 mag. I personally wouldn't go any less than 150 out of a 30.
