I have been shooting and reloading the 6x45mm for a number of years in the AR15 platform. Lately have been thinking of having a contender barrel chambered for this round. Looking at a longer seating depth is what I am trying to figure out now before I order a MGM barrel. Made up some dummy cartridges to see what COAL can be achieved with different bullets. For example the Sierra 85 grain Game King #1530 can be seated out to 2.400" pretty easy.
So I would like to ask those who have a 6x45mm what COAL they are getting and if they had the chamber throated long or not.
