Hammerli 490 – Part 4 Another great youth rifle
by B.B. Pelletier
Today, I’ll scope the Hammerli 490 Express and test it again at 21 yards. Thankfully, the rifle has a scope stop built in. After yesterday’s demonstration of how scopes and mounts move under recoil, I hope all of you are convinced. If not, prepare for a lifetime of “scope shift.”
I installed a Leapers 3-12×44 Mini SWAT Mil-Dot scope in two-piece rings of medium height. No particular reason for choosing this scope other than convenience.
Quick sight-in, then on to shooting
After three sight-in shots, I was zeroed. I went back to the 21-yard bench and started shooting. Crosman 7.9-grain Premiers had been the most accurate with open sights, so I started with them. Would you believe I couldn’t settle down? I shot group after group measuring about an inch c-t-c and my shots were stringing vertically. That’s always due to hold with a springer, so I tried several alternative holds, but in the end settled back into the artillery hold described in part three.
The second time the rifle grouped better, but try as I might, I could not get the rifle to group any better than it did with open sights! It was very frustrating, because I know this gun can shoot. How am I so sure? Take a look at the one good group I managed to shoot and you’ll see.
The groups did get smaller, but nothing was smaller than the half-inch I shot before. Thinking it was the pellets (yeah, sure!) I switched to RWS Hobbys that had also done well in the open sight test. But they didn’t group any better this time, either.
One last thing I wanted to do was check the velocity after all this shooting. The rifle is partially broken-in now, and I wanted to see what that did to the velocity.
Premiers settled down to 504 f.p.s., with a low of 495 and a high of 513. Hobbys averaged 496 f.p.s. with a low of 483 and a high of 508. So, the velocity is lower and more consistent. It’s very close to the advertised velocity of 495 f.p.s.
It’s not the gun, the pellets the scope or the mounts. It’s me, and I know it. This rifle should be able to lay them all on top of one another, but I just wasn’t up to the task. I would like to blame the heavy trigger somewhat, but since I shot better with it the other day, I can’t use that excuse, either. So, I’m setting the gun aside for a few days, and I’ll try again.
