ITEM 45B 275 XPB


SUPERCHARGED 450 BUSHMASTER LEAD-FREE AMMUNITION

Written 03-2018

As of this writing (03-2018) we’ve been getting requests to make some heavy duty 450 Bushmaster loads since the cartridge was introduced around 10 years ago.

This is a cartridge that will hammer North American big game species, mostly because of its caliber. We are making four loads (which are all-purpose designed) to cover your hunting needs from smallish whitetails to bull elk, grizzly, and moose. If you know your range and understand your bullet drop, there is no reason not to use this cartridge out to 250+ yards.

These are our four current (we may add more at some time) 45 Bush loads and their projected velocities. We will post real world velocities obtained from our test guns with each load.

1.  Item 45B 250 JHP -- 2,250 fps
2.  Item 45B 275 XPB -- 2,000 fps
3.  Item 45B 300 JHP -- 1,950 fps
4.  Item 45B 360 HC -- 1,750 fps


As each new load becomes available, we will write a short tech article about its intended uses and limitations.

With regards to Item 45B 275 XPB, This load is very versatile. Due to the expansion characteristics of the Barnes XPB bullet, This load will give the velocity of a 275gr. bullet, but the penetration of a much heavier typical lead-based bullet. This bullet will work well on small animals like whitetail and still work on bigger animals like moose or elk. Even at close range, this bullet will not disintegrate if large bones are hit. Typically, expect penetration of between two feet and up to 4 feet, depending on impact velocity and which bones, if any are hit. If I wanted one load to do everything, this would be my load of choice. There are better deer loads (see item 45B 250 JHP) and better protection loads against dangerous game over 1,000 lbs., but for a “do-all” load, it would be impossible to beat this one.

You can see my posted velocities below in real world, over-the-counter firearms, for item # 45B 275 XPB.

➤  Ruger All American------------------16-inch-----------------------2,008 fps
➤  APF AR15-------------------------------16-inch-----------------------2,027 fps
