Just resized my 280 AI with Redding dies Imperial wax had to remove decapping rod to break the vacuum on the up stroke. Will gladly trade my Redding 280 AI dies for same in RCBS with a vent relief hole!!!! They stretch cases on the up stroke, less tapered
cases like the AI is where I see the most issues.
