Today we look at the accuracy of the new Hellboy semiautomatic BB gun. Let’s get right to the test.

The test

I shot the Hellboy off a UTG Monopod rest at 5 meters. I said in Part 2 that if the gun was accurate enough at 5 meters I would extend the range to 10 meters for another test. We will see today if that is going to happen.

Reader GunFun1 wanted a video of me shooting at a can, but that’s not interesting for several reasons. First, if the can is missed the viewers have no idea by how much. And hitting a soda can with a BB gun doesn’t show up well on film. It’s better in person. But if the Hellboy is accurate enough, I have a plan for how to do what GF1 wants.

Air Venturi Steel BBs

First up were Air Venturi Steel BBs. Ten of them grouped in what looks like 1.492-inches at 5 meters, but you are only seeing 9 of the 10 shots. One landed off the paper to the left, enlarging the group to 1.961-inches between centers. We are not off to a good start.

The Hellboy put 10 Air Venturi Steel BBs in 1.961-inches at 5 meters. One shot was off the target, about 3/8-inch to the left of the paper.

Adjusted the sights

The Hellboy was shooting to the left, so I adjusted the rear peep to the right about 10 clicks.

Hornady Black Diamond BBs

Next I loaded 10 Hornady Black Diamond BBs, which I thought might be best in the Hellboy. They made a group measuring 1.846-inches between centers, which did turn out to be the smallest of the test.

Adjusting the sights didn’t seem to move the group much, so after this target I adjusted them again. The rear peep is now very close to the right side of the carry handle.

Dust Devils

Next to be tested were Air Venturi Dust Devils. The first shot landed to the extreme left of the bull and I thought the sight adjustment had not made a difference, but shot two hit to the right of the bull. I knew right then that Dust Devils were not going to do well in the Hellboy. And I was right. After it was all over 11 Dust Devils had gone into 3.968-inches at 5 meters. Why eleven? No idea. I just miscounted.

Eleven — yes, there are 11 holes in this target — Dust Devil BBs made this 3.968-inch group at 5 meters. This is definitely not the right BB for this airgun.

I had planned to only shoot these three BBs in today’s test, but the lack of accuracy made me want to try one more BB — the Air Venturi Smart Shot. These lead BBs sometimes deliver surprising results.

Not this time though. Ten Smart Shot BBs shot at 5 meters landed in a group that measures 2.283-inches between centers. That puts them behind the Black Diamonds and Air Venturi Steel BBs.

Nothing I shot out of the Hellboy seemed to make any difference. The gun is adequate but not that accurate. For this reason I will not be continuing to test it at 10 meters. You have already seen how a BBs accuracy can fall apart as the distance increases, and this is not the place where I want to start.


The Hellboy has several things to recommend it. It’s very realistic, it handles BBs well and it is relatively powerful. The carry handle detaches for an optical sight to be mounted on a Picatinney base on the flattop receiver.

On the other hand, today’s test indicates it isn’t the most accurate BB gun around. If you plan to shoot gallon jugs in the yard it will do. If soda cans are your quarry, better stand close.
