Good photo. It makes it sound like essentially the same as a 300-grain .45-70 you can buy today. I notice it says "low pressure" and "adapted" but does that mean they shouldn't be used in Springfield single shots? Just asking; I don't have one anymore. I also notice it says not to reload them. And are they jacketed bullets?
Shoot low, sheriff. They're riding Shetlands!
Underneath the starry flag, civilize 'em with a Krag,
and return us to our own beloved homes!
