Gamo V3 - Part 2
by B.B. Pelletier
Do NOT add Crosman Pellgunoil to a precharged pneumatic airgun as mentioned in the Bam B51 report, Part 2. I have learned that someone once received a petroleum specification sheet with the Pellgunoil they bought that indicated it was straight 30-weight non-detergent oil. If that is true, it is very dangerous to introduce petroleum oil into a vessel containing compressed air. It can form a fuel-air mixture and become explosive. I believed that Pellgunoil is a synthetic product with a high flashpoint, but there is a good chance I AM MISTAKEN.
This warning is to contradict the information I presented in the BAM B51 report, part 2.
Before we begin today, there is something I need to say. For several years, some readers have been asking who I am. Some ask me to post my picture (like I can't figure THAT out!) while others just ask. Then there are the chat forums where people talk about me and tell others in a condescending tone exactly who I am. This has gone on too long.
Two weeks from today, on Thursday, October 18th, I will pull back the curtain and reveal who I am. And I will do more than that. I will explain the entire philosophy behind this blog.
There are some other pressing reasons for this. It isn't just provoked by curious readers.
For those of you who were saddened when Superman was killed (either George Reeves or the comic book hero - take your pick), I will not be pulling an Obi-Wan Kenobi.
Now, on to today's post. Apparently, the Gamo V3 hits a nerve with some of you. Vince responded first to yesterday's post and explained that the simulated blowback is viewed by many as a flaw rather than a feature. I went to the Gamo website to look for false claims, and found one confusing and inaccurate phrase. They correctly state that the slide slides back and forth, but they added the modifying phrase, AFTER EACH SHOT. Of course, that is NOT how it works. The sliding comes BEFORE the shot. AFTER the shot sounds like blowback. BEFORE sounds like nothing anyone has ever seen - well, almost no one. There was a firearm pistol that had a trigger to cycle the slide for the first shot. That's SORT OF similar - to make a huge stretch.
Of course, Pyramyd Air copied that flawed description from Gamo, so I alerted them to the error and they've already corrected it.
I still think the V3 has many interesting innovative features that address the concerns of the BB pistol market. But those were addressed yesterday. Let's shoot! Because this is a BB gun and I want to use a Crosman model 850 BB trap to catch the shots, I will first determine the velocity. If it's over 450, I'll use a Quiet Pellet Trap instead of the 850, because the ballistic curtains can't take the strain of repeated higher velocity rounds.
The test pistol is all over the place! Using Daisy Premium-Grade BBs, I recorded velocities from 314 f.p.s. to 431 f.p.s. That's a huge spread, and I gave the pistol a chance to settle down, thinking that the wide swings were due to break-in. But they didn't seem to be.
Next, I tried Crosman Copperhead BBs, thinking that the pistol might not like Daisy BBs for some reason. The Crosman BBs ranged from a low of 244 f.p.s. to as high of 418 f.p.s., but I discovered a trick while shooting them. This pistol does not like to have the trigger squeezed slow and deliberate. It wants fast and furious. Squeeze it slow, and the velocity varies all over the place. Shoot fast, and it stays above 400 f.p.s. for most shots.
Well, not too fast for the Crosman trap, so the next stop was the garage range, where I backed the trap with a piece of 3'x3' particle board. Although the longest distance I can get there comfortably is about 15', I didn't know what sort of "pattern" this gun would produce at that range.
Not too bad, as it turned out. The gun shoots a little high and to the left, but that's probably because I'm shooting doubl-action. It groups in an area the size of a palm (hand, not tree) at 15'. The trigger, which probably breaks around 12 lbs. as given in the specifications, is long and creepy. Add to that the fact that the pistol wants to be fired fast, I'm just glad to have kept all my shots on the paper. Knowing it was at least that good, I went out into the backyard where air pistols like this really shine. Without a lot of difficulty, I kept a twig 20 feet away in fear of its life for the entire magazine. I don't think a soda can stands a chance, once you discover where you're really shooting, which for me is a little high and left.
Don't overload the magazine!
I learned this lesson the hard way - twice! Put just one BB more than the recommended maximum of 15, and the entire magazine will dump its contents. When you insert the overloaded mag in the gun, the follower pushes to the side and locks itself out of commission. Then there is no follower spring pushing the BBs up and the gun won't shoot a BB. All it does is fire blanks. When you remove the mag to see what's wrong, all 16 BBs will dump onto the floor. Load 15 and no more unless you want to go fishing on the floor with a bar magnet like I did.
I forgot to mention that the rear sight can be moved sideways in its dovetail, so there is some limited adjustability. It's just a clamp-type of sight, so it isn't very precise, but if you need it, it's there. I also failed to mention that there are clamping grooves on the frame in front of the triggerguard for a laser. I think that will appeal to many owners.
I have to get personal and say that the long, heavy trigger-pull was a turnoff for me. It was so heavy that I had to shoot it with two hands, which I don't like to do. But I had to in order to control the muzzle. Accuracy was acceptable and within reason for guns in this price range. I never noticed the moving slide while shooting, so that feature was completely wasted on me. The all-plastic frame and grips made the gun feel toy-like compared to others that are mostly metal. I do like the M1911 Officer-model styling, which puts the safety exactly where it's needed.
