Hello Everyone


There are some discussion and concerns in the forum recently regarding to the velocity of Xisico USA 's model XS46U

At factory in China, we have been using RWS pellets for final products velocity check. All products velocities meet our production standard.

For your information:
0.177cal , we have been using 7gr RWS Hobby flat head pellet to conduct velocity check.
0.22cal, we have been using 11.9gr RWS Hobby flat head pellet to conduct velocity check.

The velocity referenced on our website and our manual are meet our production standard.

Thank you for your time

Xisico USA Inc.

It's very nice to get information from the manufacturer. So now we know what pellets are used for testing and that velocity claims are not inflated.

I think that this is a very good move on the part of the manufacturer. Any time a manufacturer can provide useful information to the consumer it has to benefit everyone involved. Thank you Xisico USA

Sunny,

Thanks for posting this clarification, it's helpful for all of us. This is very useful data and I will be up-dating the Archer Airguns website to reflect it.

I agree with other posters that it is excellent customer relations for Xisico USA Inc. to post useful data like this on the Forum!

I'm not completely shocked by the trend of this comparison as I've found fairly similar results myself with the Ruger Air Hawk in .177 caliber. The Air Hawk shows a clear preference for lighter - actually lead free - pellets and gives a muzzle energy increase of 16% when compared to medium weight lead pellets.

Yes, 16% is not 30%+ in muzzle energy terms, but it does show that some spring-powered airguns can have a strong preference for very light pellets.

In extensive testing with the Air Hawk, very light - actually lead free - pellets provide a very significant increase in both muzzle velocity and muzzle energy.

Here's the highlights of my Air Hawk tests (same gun for both tests):

- 8.56 Grain Stoeger X-Field pellets 849 fps 13.7 ft/lbs

- 5.66 Grain Stoeger X-Speed pellets 1153 fps 15.9 ft/lbs

Test targets and more supporting data can be seen in the eBook I published on the Air Hawk at http://www.scribd.com/doc/98544721/Arch ... -for-Ruger

I plan to re-test the XS46U in future with the RWS Hobby pellets.

BTW, I'm not expecting the muzzle velocity to reach exactly 1,000 fps with the Hobbys. But I would expect to see numbers of 900 fps and above. It seems to me that a maximum 10% tolerance in muzzle velocity for a value-priced spring/piston air rifle would not be an unreasonable production target - especially when we're talking of many thousands of guns being assembled in production line conditions.

If the XS46U tests at 900 fps with 7 Grain Hobbys, that would be 12.6 ft/lbs of muzzle energy - an increase of 18%. This, of course, is much closer to the results I have found myself with the Air Hawk.

Again, I support Xisico USA Inc for their positive and helpful response to this discussion. There's plenty of manufacturers that would not have done so...

...about their testing. I would believe the .177 cal of this gun can go up to 12fpe after some tinkering. Can you tell us how hard/easy it is to disassemble this gun? does it come with a leather seal? do you have an exploded view of this model? TIA.

Sam,

I'm glad to have helped. I've not disassembled the XS46U myself yet and don't have an exploded parts diagram. But judging from it's apparent similarity to the QB36-2, I doubt that would be too difficult to disassemble: a spring compressor would be required, obviously.

But I can confirm that the piston seal is synthetic and not leather.

Sure would be nice if you used standard pellet weights like 7.9 and 14.3 so the results don't look inflated. But at least we now know what you are using and can obtain the FPE so we have a real world ide of what we are getting.

Would you rather see something like "1600 fps with PBA's"? While those ultralite pellets achieve a higher fps, they seem to shed speed rather quickly and I wouldn't use them in a magnum springer. Not quite as much inertial resistance due to the lack of mass.
