Ammo used to be cheap. Maybe $5 a box of 20. Those days are long gone. I can even remember my younger days when I could get a burger, fries and a coke and change back for my $1. Back about 1990 a buddy and I went to a gun show. I had some cash in hand.
My then experience with the caliber was in the old Springfield, a trapdoor with custom handloads. They were loaded up to the very minimum for the caliber with a cast bullet. No reason to stress the old smoke pole.
So at the show I bought a Browning B78. It was a sweetie, and I don't remember how much/little I paid. And a little farther along we found a seller dumping his stock of .45/70 ammo. He'd been asking about $4 a box, but told me if I bought it all he'd sell for $3 a box. So my buddy offered to carry the rifle and I carried the ammo. No far along we found another sell who asked how much I'd paid. He said I could have all of his for $2.50 a box. So I bought it, too. Time to go to the car, all I could do to carry 10+ boxes.
I'm pretty sure I've still got it all. I've only shot reloads over the years, except for a few rounds to compare against. I've got a .50 cal can that is pretty darn heavy with loaded rounds.
And I have an affliction. I get the idea in my diseased mind that I need bullets in a certain caliber. So when I see them at a good price, I load up. And then I get home and discover I've already got too many. Only after a few cycles do I get the idea and stop. Its a good round to have and shoot.
I have no idea what I'm going to do with all the ammo. Some day soon maybe I'll die and my sons will get the guns and ammo. Who in their right mind would have that much of a nearly extinct caliber. That's what the sellers 24 years ago called it. More stories....I've got 3 or 4 sets of dies. Don't remember how I got them. Don't care.
