Cometa Indian spring-piston air pistol: Part 2
by Tom Gaylord, a.k.a. B.B. Pelletier
Lots of interest in this Cometa Indian air pistol! Some of you know it already, and many more are interested in the light cocking effort. How can “they” make a gun that shoots 500 f.p.s., yet cocks with just 7 lbs. of effort? Well, today we will find out if it really does shoot that fast.
The cocking lever
Blog reader Wulfraed was puzzled by what appear to be a lopsided cocking lever. I told him that it’s really two-sided and I would show a picture of that in this report, so here you go.
On to the test
Okay, let’s get to the velocity. The first pellet I tested was the RWS Hobby. I used it both because it is a very light pure-lead pellet, and also because it’s an accurate pellet in many airguns.
Hobbys averaged 538 f.p.s. in the test pistol, so the claim of 500 f.p.s. has been vindicated. In fact, it’s conservative. The spread was from 533 to 542, so a 9 f.p.s. range. At the average velocity, Hobbys generated 4.5 foot-pounds of energy at the muzzle.
I found that seating the pellets was difficult unless I struck the back of the breech with the heel of my hand to close it after loading. Then, every pellet seated fine.
Next up was the RWS Superdome. This is a medium-weight, .177-caliber pellet that I expected to go slower. But it didn’t go that much slower! The average was 491 f.p.s. with a spread from 488 to 493 f.p.s. That’s a spread of only 5 f.p.s. At the average velocity, this pellet generated 4.44 foot-pounds of energy.
I did have a little excursion with this pellet, however. If you refer to Part 1, I showed you a picture of the open breech, in which a small o-ring is seen around the bolt probe. I lubricated this with one drop of silicone chamber oil and immediately got an increase in velocity. Then I got three detonations! The fastest went 673 f.p.s. I then had to dry off the probe and shoot off the oil until the pistol settled back down, again.
So, I advise against oiling the bolt probe of this pistol. Maybe put some silicone grease on the o-ring — but keep it light!
The last pellet I tested was our new friend, the H&N Baracuda Green. We know this is a very accurate pellet, and I wanted to see what a lightweight pellet would do in the pistol. Actually this pellet weighs 6.48 grains and the Hobby weighs 7 grains, so it shouldn’t be that much faster. The average was 568 f.p.s. with a low of 564 and a high of 575. The spread was 11 f.p.s. The muzzle energy averaged 4.64 foot-pounds. Of the pellets tested, this is the power champ by a slim margin.
The single-stage trigger breaks at 4 lbs., 13 oz. on my electronic gauge. It’s still creepy and may be a factor in the accuracy test.
From the comments that have been made, I’m anticipating a good accuracy test for the Indian. Someone said that his out-shot an Umarex Colt M1911A1. If that’s the case, this could turn out to be a wonderful air pistol. Accuracy test is coming soon!
