At least not RWS. It's widely proffered that, for whatever reason, airgun makers claim greatly exaggerate velocities in their air guns, whereas firearm ammo makers do not exaggerate (much). However, here are my findings to the contrary today. Both tested rifles are RWS and both are .177/4.5mm. Results from 5-shot strings over a Shooting Chrony Beta Master.
Rifle 1: RWS Model 34 (ads claim "1,000 fps")
Rifle 1 results:
-Crosman 10.5 grain round nose pellets (very heavy). High 868.5 fps, Low 820.8 fps, Avg 849.92 fps.
-Daisy "Max Speed" pellets - no stated weight, but undoubtedly very light. High 1066 fps, Low 1041 fps, Avg 1058 fps.
Rifle 2: RWS Model 52 (ads claim "1,100 fps")
Rifle 2 results:
-Crosman 10.5 grain round nose. High 1079 fps, Low 1035 fps, Avg 1055.4 fps
-Daisy "Max Speed". High 1370 fps, Low 1287 fps, Avg 1325.8
YMMV on other makes but this is what I'm getting with RWS. Interesting that the model 48/52 advertising UNDERstates the actual vels from light pellets by some 200+ fps.
