I am giving the .45 ACP ARX 118-grain bullets a thorough evaluation in my Springfield 1911. I’ve been using my Winchester 231 load (7.0 grains, to be precise), and I continue to be impressed with just how accurate these bullets are.
One day recently when I was on the range with the 1911 and my ARX reloads, it was very windy. I shot at 25 yards, had a decent group, and then two things happened:
-
-
- I moved the target out to 50 yards, and
- The wind picked up significantly.
-
You might call someone who evaluates a load for accuracy under high wind conditions not very bright. Hey, guilty as charged. That’s exactly what I was doing.
Under those extremely windy conditions, I was surprised. The bullets impacted the 50-yard target a foot to the right. I kept cranking in windage adjustments on the 1911’s rear sight and I still couldn’t get the bullets back on target.

Realizing there had to be more to the story, I went out to test the load again at 25 and 50 yards a few days later when the wind had died down. It was cold and foggy, but there was no wind.

I put the target at 25 yards and fired 5 rounds with my ARX load. Nice, I thought, as I looked through my spotting scope. All five shots were in the 10-ring, and 3 of those were in the X-ring.
I then moved the same target out to 50 yards and fired another five rounds. Wow, was I ever pleased. The 50-yard group was right on top of the 25-yard group, with a couple that went a little high (but they were still in the black).

The above results and my experience the preceding week convinced me of three things:
-
-
- The ARX bullets are probably more affected by wind than conventional bullets at longer ranges (not surprising, as they are half the weight of normal 230-grain hardball bullets),
- The ARX bullets are exceptionally accurate, and
- The ARX load is a relatively flat-shooting load (I didn’t have to make any sight adjustments when going from 25 to 50 yards).
-
I like these ARX bullets, and I like this load.
Next up? I’ll be evaluating this .45 ACP ARX load in a couple of my revolvers. That’s going to be interesting. I promise.
