.405 Winchester

[Contenderizer]

With enough practice one can do about anything, but I think there are better choices for pronghorn hunting. As suggested above, range is the big issue and the 405 was never intended for much beyond 150 yards. Since pronghorns don't need much lead to kill, consider borrowing a 30-06, 270, 243 or 6mm Rem from a friend. Or, if you have a really, really good friend, he might lend you his 6-1/2 Swede.

Don't mess-up what sounds like a great trip with a gun that won't reach the target; pronghorn shots are frequently quite long. And, don't forget shooting sticks and a rangefinder.
