Thanks Ash, that was what I was thinking of. Seems reasonable, just still not too sure of the wall thickness although at the pressures that would be run, probably well within the realm of acceptable.

Another question: does anyone have a load chain for a round ball at 1050fps in a nitro for black that would fall into the acceptable presusre range?

Also, what is the proper case length for an 8 like that (or is there an option?)

Thanks

Tom
