22 caliber and fps differences
For 18.13 grain JSB’s:
900 fps = 32.62 ft lbs
915 = 33.71 ft lbs
930 = 34.83 ft lbs
I’m not sure how any of this relates to real world. In other words, is the 2 lbs difference between 900 and 930 going to make a difference with accuracy at 100 yards?
Will the resulting ft lbs at the target be sufficient to kill what the pellet kits – provided shot placement is the same for all 3 fps?
Will 2 lbs make a difference in scope adjustment (holdover, etc) at 100 yards?
I would think that 900 has got to conserve a little air over 930 and 930 would cause more wear and tear on the gun to slam the hammer harder against the valve, etc.
Is the extra 30 fps worth it?

It apparently doesn’t reference a single video. Most of those are shots using m/s. When converted, most I looked at were 305 m/s and up which is over 1000 fps.
Are you saying Jan sent us bogus info?? :suprisedn:

See https://www.youtube.com/user/RusBearRB/videos there one Russian guy doing tests with speed vs lothar walther barrel. It is cricket.
Accuracy is everything!
take your time, and do some reading here. please
you will find that spread of 15-30fps make only few mms of POI differenece
I also agree with Eelect. When I got my gun it was shooting at 930 to 940 fps. As it settled in the velocity dropped down to 890 to 900 fps. I seem to think mine shoots better at 890 fps.
The only reason I would go with the higher velocity is the fact the pellet will fly flatter and will spend less time in the wind. If my gun would give me the same accuracy at 930-950 as it does at 890-900 I would shoot it at 930-950

My short take is NO. Most things in life would be boring with less options, i’m sure someone out there requires 34.83 ft/lbs. Balance is a good thing.

There is many videos with high fps. I think is too much for that pellets. I do not know if good see is there many wobble pellets…
