+1... "Kill something with them and then decide if they work."

I'm hampered by ethics, I guess. I don't want to shoot something and find out it wasn't a clean kill. That's the exact reason I got away from using a .243 Winnie. Two years ago I shot two bucks with the .243 using 100 grain Hornady BTSP Interlocks. One was a perfect lung shot and the other broke both front axles. The lunger ran off never to be found. It was close to dusk and a two hour track revealed nothing but bright lung blood. The other made a death kick, lunged forward and crumpled, then plowed the ground with his antlers until he made a furrow under a barbed wire fence and continued on. He was over 100 yards from the property line when shot, and the dense growth made a follow up shot impossible with his bucking and lunging. I didn't have permission to track the deer on commercial (oil field) property. That's what fueled my decision to move to the 7mm-08 and use 120 grainers. But now I'm looking at this bullet with skepticism confused
