I have a lovely pre-war Simson 16 that I purchased knowing it had been honed out of proof but had plenty of meat in the barrels and was still safe, bores measuring 0.674, both sides.

This thread made me take a second look and since the barrels are stamped 16/1, which according to Dig's website is 0.669-0.678, I'm still in proof.

I'll go by the rules in effect at manufacture.

My problem lies in reconciling my gross habits with my net income.
