The pictures make the whole process a lot clearer to me. For those wondering, this gun was proofed after sleeving at 3 tons. I’m very grateful for the responses. I had read on another forum that those mini shells were reportedly low pressure, but the consensus here seems to be no, and I tend to believe the folks here know of what they speak. The B&P shells seem to me to be the ticket, despite them being 2-3/4” length. At the stated pressures, it appears I can afford a spike even in excess of Mr. Bell’s findings without too much worry.
