I have a .257 roberts that is nearly impossible to find ammo for. Luckily i was able to find some and i have about 300 rounds saved up. They cost me about 250 a round when i find them. Only shoot maybe 10 rounds a year (durr killing and making sure scope is still zeroed). I can put bullets in bulletholes at 150 yards.

It's a baby .45-70 dimension wise it's about half. It's adorable and reloadable.

Abandoned as hell though. Like 3 people shooting it.

The Russians have shitloads, especially for their revolvers. I believe there's a 7.62x42R, 38R, 29R, and another as well, with most being captive piston rounds.

I'm trying to avoid fudd calibers because the list is nearly endless there.

I really want to do some ballistic gel tests on this, might be a good pocket carry in a round that expands to a small diameter but still penetrates

The SMAW has a small spotter rifle on the barrel of the actual launcher. The rifle fires a 9mm tracer cartrige that mimics the trajectory of the actual rocket.

What someone firing the SMAW does is use the spotter rifle first to assist in getting an accurate first shot with the actual rocket.
