Yeah, why not!

I'm a bit of a bower-bird myself, plenty of 1960s-era berdan-primed .303 cases from FN in a crate somewhere in my shed, plenty of RWS berdan primers tucked away too.

Hopefully the day I actually need them will never arrive!

Hopefully the day you actually need bulk-loaded military .308 never arrives either, lancaster!
Perfect for dog handler though.
...and its good to be prepared.

Good work on the tool, too. Function beats form all day long!

My own case neck straightener is a manually-operated .50BMG FMJ projectile, but I never have that many to do!
