I'm rebarreling a 22-250 into a 20 br and I'm having a hard time discerning the difference between the 20 br Remington reamer or the 20 br lapua reamer.Most reamers just have a 20 br tag. But the dies say 20 br Remington or 20 br lapua. Does this mean I can't use lapua brass? Is this something I need to be concerned about or are they both the same? Feel free to expound.
