1300KT Velocities with 14.6" or 18" barrels?

[Marc]

Does anyone have velocity numbers for a stock (no piston or valve work) 1300kt with the either of the longer barrels?  Preferably in .22 but any .177 numbers would be great too.

I don't have a crony so thanks for any info!

Mine shot 500fps with an 18-inch barrel and 14.3 grain Crosman premiers.

Thanks - that's pretty good out of the box!
