.300 Winchester Magnum

The 300 is an outstanding sniping round for military applications! But as you might imagine, it offers a lot of power and penetration, which limits its role in Law Enforcement. I am aware that the Secret Service uses the .300, but they're situation is rare, they don't have to be too concerned with hostages. They just need to insure that the possible assassin is stopped, and the .300 is a good caliber to do that. The .300 is also a great round for going through media in order to hit the target. The .300 is very capable of extending out past 1000 meters reliably, reaching 1200meters on a nice calm day without much effort. One big criticism of the .300 is the amount of recoil that the round produces. To be honest, it really does punish the shooter, making long sessions at the range a very grueling situation. If you are not careful, you can easily develop a flinch in your shooting cycle, this could be very bad. But with proper training, and a gradual migration into the .300, you can overcome this problem.

Recommendation: The .300 gets my highest recommendation for military use, but not my recommendation for Law Enforcement use. If you could find a suitable round that limits over-penetration, the .300 could be a very flexible caliber, offering good armor penetration with the change of ammo.

Military Applications

Note: The Federal Match .300 was chosen for my military round, it�s a great round and serves admirably, the 190gr Sierra Match King has a really nice Ballistic Coefficient.

Law Enforcement Applications

Note: I have chosen two rounds that could be possible candidates for Law Enforcement, I am skeptical about the penetration potential of both rounds. Please insure proper tests are executed to investigate the penetration of these rounds, and of course, always be sure you have a good backstop behind the target if the shot must be made. (Good marksmanship can make up for a lot of ammo deficiencies.)
