ITEM 45B 275 XPB
SUPERCHARGED 450 BUSHMASTER LEAD-FREE AMMUNITION
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.
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.

Good evening. I thought you'd like to know that I killed a 240-pound boar with one round of item 45B 275 XPB from 100 yards away with Ruger Gunsite Scout rifle. The boar was broadside. I aimed and hit him just behind the right shoulder. The boar dropped on the spot and died almost immediately. It bled from the mouth and nose. We recovered the bullet. It went straight through and almost exited the left side behind the shoulder. The bullet came to rest just inside his skin on his left side. I think it worked perfectly. Here is a picture of Andrea with the boar at the processor.
