I work at an equipment rental company and got to looking at our masonary selection. Specifically, I was looking at our .22 blanks for firing nails into masonary. I spotted something that was kind of odd IMO. The package was labeled 'Remington', but the blanks had 'Super X' stamped on them, which, IIRC, is a Winchester logo. Any idea why? Companys sharing casings?
