Description
.300 Winchester Short Magnum 180 Grain Swift A-Frame~ The principle at work in the short magnum cartridge is the advantage of fitting larger volumes of powder in closer proximity to the primer’s flash hole, resulting in more uniform, consistent ignition. The advantage to this round is the ballistics are nearly identical to the .300 Winchester Magnum, but in a lighter rifle with a shorter action. The .300 WSM is adequate for hunting moose, black bear, brown bear, elk, mule deer, and white-tailed deer in forests and plains where long range, flat shots are necessary. The .300 WSM is also used in benchrest shooting.

The Bullet-
For 28 years the Swift A-Frame rifle bullets have set the standard by which all bonded bullets are measured. With its controlled expansion of 2.2x and 95%+ weight retention A-Frame penetrates deep and mushrooms perfectly, making it the choice of hunters for use on any game, anywhere in the world. A-Frames are famous as a heavy game bullets in both North America and Africa. They have a spitzer or semi-spitzer shape. The A-Frame’s tapered copper jacket is divided into two sections by a traverse internal bulkhead, similar to a Nosler Partition bullet. The front half of the A-Frame has a lead core with a small exposed lead area flush with the tip of the jacket (what Speer would call a “mag-tip”) and mushrooms in the manner of a tough, bonded core, soft point bullet. The heavy partition amidships positively stops expansion at that point, keeping the rear half of the bullet, with its separate lead core, intact for deep penetration. The base of the jacket is folded over the back of the rear core to prevent it slipping. All A-Frames are flat base bullets and lead is exposed at both ends. Both cores are bonded to the jacket to prevent separation of jacket and core. The A-Frame’s exceptionally thick jacket and bonding of the lead cores to the jacket results in very high weight retention after impact, claimed to be around 95%. The A-Frame is a controlled expansion, lead core bullet with weight retention comparable to mono-metal bullets!
