mr.pepperHow low can you go?
Trim length for the 480 Ruger is 1.275.
Some of the brass Speer and Hornady are
measuring 1.274 to 1.272 The rest is 1.275 to 1.280 which I have trimmed and deburred.
How low can I go before I toss the short brass?

Ol` JoeHow low I don`t really know but, since the cartridge head spaces on the rim, as long as you are not seating deeper then the listed COL in your data and still crimping the mouth in the bullet canalure I wouldn`t worry.
