Testing the Gamo Whisper - Part 3
by B.B. Pelletier
Let's take the Gamo Whisper to the range, although the day was not good for shooting. I also tried to shoot some 75-yard groups with the Air Arms S410 sidelever, but a 15 mph gusting wind ruined that attempt. I haven't given up, but I do need to adjust the scope mounts before returning for a second attempt on a calmer day.
However, I do have more to report on the Whisper, because this day I had a gallery of four other airgunners to watch me shoot and handle the rifle. To a man...even though one was a woman, they liked the light weight. She was surprised by the light cocking, so it wasn't just my imagination.
One person, who is in advertising, was most impressed with the TruGlo sights. He said he would feature them plus the light weight in an ad, but he would avoid mentioning the one thing the gun isn't, which is quiet. Not that it's noisy, mind you, it's just not that quiet. It sounds like most other spring guns in its power class, though perhaps on the quieter side of all of them.
I tried to sight-in the rifle, and I had it on at 10 feet, but at 20 yards the wind blew the pellet clear off the paper. It's not fair to the gun to report the groups I got, so I'll return on a better day. But from what I saw at 10 feet, my gut tells me this rifle can shoot.
Trigger not so good
Remember that trigger I've been praising? Well, off the bench it's positively bad! Too much second stage for any hope of good work. It's not particularly heavy, breaking at between 5 and 7 lbs. I know, I know...Charlie Da Tuna. Give me some time.
Velocity was a pleasant surprise!
Gamo advertises the Whisper at 1,000 f.p.s. with light lead pellets and 1,200 f.p.s. with PBA Gamo Raptors. So, I shot it with Crosman Premiers (7.9 grains) and Raptors (5 grains), and I'll be darned if it didn't get pretty close! Raptors went an average 1175 f.p.s. and Premier lites went 918. So, Hobbys might go 950 or so, and that's pretty close to the advertised velocity.
The powerplant now buzzes more than it did, and that's where the bulk of the noise is generated. I'm not going to tune this rifle, but if it were tuned to be quieter, then the muzzle reduction might begin to matter, as it does with the TX 200.
In the next installment, I'll scope the rifle and go for accuracy. After all, you guys don't care how lousy a shot I am with open sights.
