Thanks, Nighthawk. I will check that out as well. FYI, here's an excerpt and link to the article that got me interested in the .223 wssm. Its about a test deer hunt they did here in my home state. Impressive...
"We took a total of 13 deer with the new 64-grain .223 WSSM on the hunt, including one 207-pound trophy buck that went down at 125 yards. All were one-shot fatalities. All fell within the same distance of initial point of impact, as I would have anticipated with similar shot placement from a .30-30, 7mm-08, or similar "standard" deer cartridge. Typically, the bullets did not exit, but bullet upset was explosive and internal organ damage was devastating. One hunter placed a shot in the base of an approaching deer"s neck at about 65 yards that did penetrate through the opposite front shoulder. The exit wound was more than three inches in diameter with completely shattered shoulder bones exposed. I shot a large doe at 75 yards from the quartering rear, impact just in front of the last rib into the thoracic cavity. No exit, but the collapse of the expansion shock cavity expelled lung tissue and internal organ debris more than 10 feet back out the entrance wound toward my position. The deer ran about 50 feet, with massive bleeding, and collapsed."
