Something else I have right now is a knee recovering from extensive surgery. New ligament, multiple repairs to extensive chondral defects -- they went in with hammers and punches fracturing the ends of my tibia and femur to get new cartilage to grow. Been in quite a bit of a state lately and I need to mind the doctor's orders in rehab.
Standing on it is not only an absolute pain (!!), but the time it'll take out in my shop to do this will border on torture.

I have this rifle for evaluation.
It's a double rifle and I want to see how it'll do before I wrap my fuzzy sense of ownership around it.
Double rifles are notoriously sensitive to such things as bullet shape and weight, and this thing looks an awful lot like a roundball gun.
I'll say this at least, bore size double rifles tend to have more latitude, to be less 'load sensitive' than the high-strung cordite express rifles. Hopefully this will work to my advantage.

I would like to get some pure ball in the range of .620+" to about .630" to test it with before I commit to tooling etc.
I'm already going to have to make my own cases for it, and I'm trying to keep the time on my feet in the machine shop to a minimum right now. It's a cold cramped bitch of a space to navigate in my current condition and I just want to get this thing to the ranch and run it.
It would be freakin great if someone actually made something between .610" and .648"
Just doesn't seem anyone does.

Go figure.

Thanks for the advice.
Believe me I've been thinking of all the ways I could get myself set up on my own.
I'd really love to at this moment be able to skip out there and make some chips.
