You have a Long action. 30-06, .270, 25-06 etc are long actions and measure around 5" from action bolt to action bolt (these are found on the bottom of the stock, they screw the action into the stock). Short actions are .223, .308, .243, etc. They measure 4.27 from bolt to bolt on staggerfeed actions and 4.4 IIRC on Centerfeeds.
