Barnes Pioneer 45 Colt 200gr TSX – Proven All Copper Load

Description

Barnes Pioneer 45 Colt 200gr TSX brings a modern monolithic bullet to a cartridge introduced in 1873. The .45 Colt has never needed help making a large hole, but bullet construction has always been its constraint, and a solid copper projectile addresses that directly.

Copper in an Old Big Bore

The .45 Colt throws a .452 inch bullet at moderate velocity, which is a combination that has been killing things effectively for a century and a half. Traditional loads use cast lead or jacketed soft points, both of which work, and both of which are limited by what happens on impact.

Barnes Pioneer 45 Colt 200gr TSX gives you predictability through its all copper revolver bullet. The TSX opens into four petals and retains essentially all its weight, so penetration depth is consistent rather than dependent on how the lead core behaves. In a cartridge where the frontal area is already large, that consistency is the main thing left to improve.

Two hundred grains is light for the .45 Colt, where 250 and 255 grain loads are traditional. Copper is less dense than lead, so a 200 grain copper bullet is longer than a 200 grain lead one, and the reduced weight keeps overall length and pressure sensible while retaining the penetration a monolithic bullet delivers.

Barnes Pioneer 45 Colt 200gr TSX Specifications

Barnes Pioneer 45 Colt 200gr TSX is a 200 grain load using the Barnes TSX, 20 rounds to the box, from Barnes Bullets. The Pioneer line covers revolver and lever gun ammunition with bullet profiles that work in cylinders and tubular magazines alike.

Because the projectile is solid copper, Barnes Pioneer 45 Colt 200gr TSX is a 200 grain lead free load, legal where non-lead ammunition is required. That includes California and an expanding set of federal refuges and state wildlife areas, several of which cover the kind of close range hunting a .45 Colt is used for.

Pressure level is the thing to understand with any .45 Colt ammunition. The cartridge is chambered in everything from replica single actions built to nineteenth century pressure standards to modern Ruger revolvers that tolerate far more. Factory ammunition like this is loaded to the standard SAAMI pressure that is safe in all of them, which is the right choice for a general-market product.

Expansion Velocity and Realistic Range

The copper bullet in Barnes Pioneer 45 Colt 200gr TSX needs velocity to open, and the .45 Colt at standard pressure is not a fast cartridge. From a five inch revolver barrel this load is working in the lower part of its expansion window; from a lever carbine it gains several hundred feet per second and performs considerably better. Know which platform you are shooting.

That said, a .452 inch bullet that does not expand at all still makes a large hole and penetrates deeply. The failure mode here is unimpressive expansion rather than a bullet that comes apart, which is the more forgiving of the two ways a hunting bullet can disappoint you.

Range with Barnes Pioneer 45 Colt 200gr TSX is short, and always has been. Treat this as a fifty yard revolver load and a hundred yard carbine load. The trajectory is a rainbow past that, and there is no bullet design that changes what a heavy, slow projectile does after a hundred yards.

Hunters who want Barnes Pioneer 45 Colt 200gr TSX in a revolver or lever carbine on deer and hogs at close range, particularly where lead free ammunition is required.

For a heavier traditional bullet in the same cartridge, the Pioneer 45 Colt 250gr uses the thick-jacketed Barnes Original instead. A Heritage 92 lever action in .45 Colt gives you the barrel length that gets a copper bullet properly into its expansion window.

Store Barnes Pioneer 45 Colt 200gr TSX indoors and dry. Avoid cycling the same rounds in and out of a chamber repeatedly, because straight wall cases allow a bullet to set back over time and a shorter cartridge raises pressure.
