Swaging heavy .22 air rifle pellets?

[guidodg]

I have been reading the Corbin site regarding swaging your own air rifle pellets.
Does anyone have any experience with this?
I want to try and make some heavy .22 pellets to use in the Talon at 40ft\lbs+. How heavy can the .22s be and what energies could I achieve?
Accuracy at 50m + ?
See http://www.corbins.com/pellets.htm
