Some of us need ‘em, some guys didn’t. I had a chart last time I was there, and a handheld GPS. But, the guide on the last church retreat I took there as a kid, perhaps 45 years ago, didn’t. Canoeing around for a week, he knew where he was. He had canoed all over the world. He guided at Y camp Menogyn for thirty summers.
He had a wood framed, canvas covered canoe that was an antique, then. Wonder what happened to him?

Anyway, back to proof. A while back, I noticed that pre 1923 French single proof at 65mm is the exact same pressure level as the 1000 Spanish proof applied to my 3” chamber Uggy, 14,233. I haven’t concerned myself with what I feed the Uggy, and would feed it steel or some other nontoxic if the powers that be told me to. Maybe not the 1500 FPS stuff they sell, but, it is a rainy day gun, bought without a lot of concern for how it holds up. It’ll last as long as me.
Same with the Frenchy. I have been feeding it 2 1/2” ammunition, don’t have a ton of it left, but, I’d sneak a 2+3/4” AA light target load in, here or there without too much concern. Same deal, rainy day gun (I have wealth in rainy day guns).
