In just about all of my guns I get a tad better accuracy with XTPs than with Deep Curls. Not enough to matter for hunting, so I hunt with Deep Curls because I have total faith in their performance. But if I get inch and an half five shot groups with XTP's in a particular gun, I expect two-inch groups with Deep Curls. But I won't hunt with a gun that I can't get to shoot five shot 100 yard groups into three inches or less.
