Testing out the accuracy of Wolf ammo

A few weeks back, I tried to do a scientific comparison of Wolf and Prvi 62gr factory ammunition to see which was better through a 1:7 twist AR-15 rifle.We did a blind test, with me firing six rounds of each at a target and comparing them. As it turns out, the Wolf was just about as accurate as the Prvi Partizan ammo, which cost almost twice as much.

Wolf vs. Prvi

The difference in the variance between the groups made by Wolf 62gr and Prvi 62gr was not statistically significant. This sparked some debate about the fitness of wolf 55gr ammo, with the thought that it was worse than the 62gr offerings. Being smart-asses, we took it upon ourselves to find out if this was true.So we went to the range today to test the hypothesis that Wolf sucks.

Let’s talk a little science before we get to the results. Our hypothesis was that Wolf 55gr ammunition shot through a 1:9 barrel would group worse than 62gr Wolf shot through a 1:9 barrel. Our research showed that 62gr would stabilize adequately in a 1:9 barrel, as would 55gr, so twist rate was not an issue in this test. We set up an IPSC target at 50 yards with 5 black dots drawn on it. We had previously attempted to zero the rifle using Wolf 55gr ammo, but as we’ll see the rifle was still slightly off (but predictably and consistently, and so not a factor in the final conclusion).

The target, before firing

Using my new 16″ DPMS upper, I fired three rounds of ammo at each dot, Nate loading the rifle out of my sight and handing me a hot weapon, eliminating my ability to tell which ammo I was shooting.Nate also kept track of which ammo was fired at which dot. Following one complete round (3 shots at each dot) he then randomized the ammo sequence, telling me which dot to fire at each time (to keep the same ammo fired at the same dot from the first round). I fired each round carefully, taking aim each time, however I am by no means an expert marksman so take these results with that in mind (although I do shoot 1 inch groups at 100 now with my Noveske upper).

The test rifle

We decided not to just test Wolf vs. Wolf, but a number of other ammunition types as well. Unfortunately, we were unable to secure any more 62gr Wolf, but as we saw from the last test, the difference in ballistic properties between Wolf and Prvi was not statistically significant, so we used some Prvi ammo instead as a control. Ammo used in this test:

  • Prvi Partizan 62gr .223 ($11/20)
  • PMC Bronze 55gr .223 ($8/20)
  • Wolf 55gr .223 ($5/20)
  • Tula 55gr .223 ($5/20)
  • Remington 55gr SP .223 ($12/20)

After the full course of fire, the results were extremely surprising.

According to these results, Wolf is actually the most consistent ammunition we tried in 55gr.

Conclusion: Buy Wolf, it’s cheaper AND BETTER!

I know, we were as amazed as you are. I encourage someone to repeat my experiment to confirm / repute my results.

So I went to the range to do a side-by-side comparison of Prvi Partizan 62gr .223 Rem ammo and it’s Wolf counterpart.

As we saw in my last post, based on my observations, Prvi was patterning worse than Wolf usually does. But that’s not a fair test. Here’s both, side by side. Left is Wolf, right is Prvi:

But that wasn’t a blind test, I knew which ammo I was shooting. So my friend MazeOfTzeentch loaded 4 mags and handed them to me, blind. Just so happened that left was Wolf again and Right was Prvi.

As we can see from the blind test. Wolf and Prvi appear to be pretty similar. Both targets were at 50 yards through my pretty princess AR.

According to these results, Wolf is actually the most consistent ammunition we tried in 55gr. PMC Bronze was a close second, with one flier loaded slightly hotter than the rest. The remaining ammo was beyond the standard (variance*2) test and therefore statistically less accurate.
