Details man, we need details. Ohh and pics.

So what is the donor gun? Did you build a monoblock or cut and sleeve the old barrels? Anything to hide the joint where monoblock/barrel stubs meet the barrel? What was the original proof? What did you use for a proofing load? Did you have any change in tolorences after the proofing load? Is it already regulated or are you still building loads for pressure? What load do you want to use?

These are just a few questions. i could ask more.
