well your cannon is considerably larger... also you said you were getting some barrel flex so that along with highter pressure could have been why it cracked.

what pressures are you running at? i am thinking you are cosiderably higher than me...

I'm typically firing between 100-160psi.... the cracks ran lengthwise, could be from some of the 2lb loads I was launching... :twisted:
