Since it’s the giving season, I decided to bring a pile of different ammo types to the range for some quick and dirty testing. Ammo makes great gunny gifts by the way. In these times of scarcity, your giftee will know you worked for it!
Speer Gold Dot ammunition features bonded construction, meaning the lead core is surrounded by a chemically “stapled-on” jacket. This means two things. First, the jacket and inner core stay together which helps penetration. Second, expansion is almost always even and predictable. You can shoot most any Speer Gold Dot ammo into water or ballistic gelatin and it will expand perfectly. Where things get a little weird is when bullets have to pass through barriers – especially heavy clothing. Any type of hollow point ammo can clog up and inhibit expansion.
I was keen to try this .45 ACP 200 grain +P load because I’ve had mixed success with standard pressure .45 ACP 230 grain hollow points when exposed to heavy clothing barriers. The lower velocity of the full 230 grain projectiles tends to make expansion an iffy proposition. This load is not only lighter, and therefore can be loaded to faster velocity, it’s a +P load which gives it a little more energy boost.
I measured the velocity of this ammunition at an average of 1,047.7 feet per second with a Shooting Chrony Beta Master Chronograph placed 15 feet from the muzzle. Not shabby at all for a .45 load, right?
To provide some challenge to test expansion, I shot through two layers of thick leather and four layers of fabric. Two out of three projectiles expanded properly. The third got all cloggified with leather and barely started to expand. The largest expansion measured .748 inches in across – nearly 1.7 times original diameter.
The loads shot to point of aim and recoil was not perceptibly different than the 185 grain loads I normally shoot.
If you’re looking for a little extra zip for more predictable expansion performance, check out the Speer Gold Dot .45 ACP +P 200 Grain load. It’s still heavy, but a couple hundred feet per second faster than a standard pressure 230 grain alternative.
