Ari Venturi M8
Air Venturi M8 is very much like the Bronco.

Part 1
Part 2
Part 3

This report covers:

  • First group high — Falcons
  • JSB Exact 8.44-grain were best
  • JSB Exact 10.34-grain domes
  • JSB Exact RS pellets
  • The final pellet
  • Conclusions

This is a test of the Tech Force M8 breakbarrel air rifle at 25 yards. We learned in Part 3 how best to shoot the rifle, which is directly off a sandbag. We also discovered that, of the pellets tested, the best to that point were Air Arms Falcons, seated flush with the breech. That is where today’s test begins.

First group high — Falcons

I was surprised to see the same pellets that had been okay at 10 meters landing 1 inch higher and 1/2-inch to the left at 25 yards. Some movement is expected when you move from 10 meters to 25 yards, but not usually that much. The first group that you see below was actually fired at a bull beneath it. The good news is the pellets were landing higher, which meant I could adjust the scope to shoot lower. That’s almost never a problem.

The first group started out well but then I threw 5 shots wide of the main group and ended up with a 1.321-inch 10-shot group. That’s a little larger than I had hoped — even for 10 shots.

Ten Air Arms Falcon pellets made this 1.321-inch group at 25 yards.

JSB Exact 8.44-grain were best

Next I tried 10 JSB Exact 8.44-grain domes that one of our readers favored. They proved to be the best pellets for the M8 I am testing — putting 10 in 0.995-inches at 25 yards. The group is fairly round, which I always like to see.

Tech Force M8 JSB 8.44 group group
Ten JSB Exact 8.44-grain domes made this nice 0.995-inch group at 25 yards. This was the best group of the test.

JSB Exact 10.34-grain domes

Next up were some JSB Exact 10.34-grain domed pellets that another reader recommended. These were a bust in the test rifle. When the first 6 landed over than 2-1/2 inches apart, I stopped shooting.

JSB Exact RS pellets

Next I tried some JSB Exact RS pellets that I thought might do well. They fit the breech snugly, but after the first 5 landed in 1.267 inches, I stopped shooting. Clearly this was not the right pellet for the M8 I’m testing.

Tech Force M8 JSB Exact RS group
Five JSB Exact RS pellets landed in 1.267-inches at 25 yards. This is another average pellet for the M8 I’m testing.

The final pellet

At the end of the test I returned to the Falcons, just to see if I had gotten any better as I was shooting. The first 5 pellets landed in a group measuring 0.995-inches, so another 5 might have opened that up a couple more tenths of an inch. At any rate, I did not feel like the Falcon was the best pellet for this rifle and I ended the test.

Tech Force M8 Falcon group 2
Five Air Arms Falcon pellets made this 0.995-inch group at 25 yards. It’s okay, but when I already shot a 10-shot group the same size with a different pellet I figured why not stay with that one?


This was a thorough test of the Tech Force M8 rifle. We now know that it is a very close cousin to the Air Venturi Bronco that has been discontinued. It has the same easy cocking, light weight, and wonderful 2-stage trigger that was found on the Bronco. It also has a conventional stock instead of the Bronco’s western-style stock. Many shooters will appreciate that.

In the 2 accuracy tests we saw that the M8 is a decent airgun — especially for the low price. You can spend a lot more and get disappointed. With the right pellets it should put 10 shots into about an inch at 25 yards. Five should go even smaller — perhaps 0.6 inches, or so.

If you want one, act now because when the supplies in stock are exhausted there won’t be any more M8s, either. I will keep looking for rifles of this power and price. When I find them, you’ll be the first to know.
