If I have a 300lb B&C whitetail give me a crack at him this season, I would welcome that performance.
We've been using Barnes X bullets EXCLUSIVELY at our camp for the last 11 years. We started with the X, the XLC and are now all on the TSX. The rifles are .308 Win, .30-06, 7mm Mag, 300Win and 300Wby Mag. We must have downed 100 deerfrom 80lb doe to a nearly 300lb buck and bullet performance was flawless. All deer either dropped in their tracks or stumbled a few feet and fell.
A buddy shot a buck (maybe 170lbs) through both shoulders with his 300WM and a 150X bullet.ML was around 3300fps and the deer was about 40 yards broadside. The entrance hole was about caliber size and the exit about an inch and a half - at most. However, when we skinned it, we saw that it was pretty much pulverized. Both shoulders were comletely destroyed. The lungs were liquified. Did this deer die quickly? Yep
