Gamo Bone Collector speed test

[Temesvar]

Any Gamo users out there that have one rated at 1100 fps, what are you actually geting?
Have a cheap chronograph, so I don't expect accuracy. Is more for comparison. My Gamo Bone Collector .22 is rated
at 1100 fps. I understand that is for alloy pellets, and still, is inflated for selles purposes. But... I barreley get 740 fps with
14.66 gr. pellets. That is less than 70%. Yet the Weihrauch, .22 rated 740 fps shoots 680 or more with same pellets. 92% !!
Love the Gamo, is fairly accurate, and powerful. Was just wondering if there is something wrong with it. Any Gamo users
out there that have one rated at 1100 fps, what are you actually getting?

That is fairly normal.

 

[Treefrog]

That's pretty much normal. Velocity sells airguns! I think that the optimistically published velocities are done with really light pellets.

I recall being very surprised when the Quest 1000 put out a 7.1g pellet at 996-fps. I still hate shooting the thing, but there it is.

Cheers,

Seems most companies want to represent their products in the most glowing terms possible (be it factual or not!). Don't think I've EVER seen a gun perform at speeds their companies have represented. Glad I learned to look for ACCURACY, not speed claimed by the manufacturer.

My Gamo Magnum.177 rated at 1650 fps.
1250fps with light lead pellet.
850fps for a 14 grain slug.
Pretty accurate for new and not broken in.
Here’s a 10 shot group at 15 yards with the slugs

Ya, based on the lightest pba pellets .

You go normal lead weights and you get normal average fps rates

So then, how come Weihrauch is more than 20% closer to reality?

They use normal pellets .. not 4 grain pba to bolster results ..

I'd say hw stays in the norm lead ranges of 8 - 10 grain stuff .

At least that's how I recall it explained over many years of this ..


Edit...

If you read gamo and hatsan state the pba use ...

Gamo example ,(.22 @ 9.7g)

1,300 feet per second (fps) with Alloy Pellets

Is your .22? If so, I have the Bone Collector Gen2 in .22 and can run chrony numbers for you tonight to compare apples to apples

Is a gen3i in .22. Has the nitro piston IGT Mach1 Now chronograph's may not all read the same. But is a good idea of what the gun is doing. I am using a H&N Field Target Trophy 14.66, but have many others did not use lately.

 

[Hateful McNasty]

It's amazing how just a little weight and shape can cause a swing in fps .

Heck I seen a slightly heavier pellets out fps a lighter one

 

[beerthief]

wonder what a TX 200 launches a 5.5 G alloy pellet at ? i will have to try that ! i have some Gamo 5.1 crappy pellets i will give it a try ? Maybe the almost no back pressure could hurt the TX ?

Mine is the same with the gas piston
. Mine has a bore/barrel on the big side. I had to go with H&N FTT in 5.55mm for good fitment//grouping
Have you pushed a pellet through the barrel yet to determine if the pellets you are using fit decent?

Fit is good. Did you get the trigger yet?

Not only the speed, but also the trajectory. Different pellet brand, different grouping spot.

I did get the trigger. Need a pivot pin for the new trigger. As the pin is molded into the plastic trigger. So nothing to hold new trigger in position

The new trigger has two pins in the bag! Should have everything you need.

Only thing in the bag was the trigger and Allen wrench

Call them up. GRT 4G. Has two pins, The one they sent you is for Gamo with steel trigger. Not sure, I may only used one pin.

Ahh. There lies the problem. I got the GRT3
