I shoot a lot of cast bullets in my .308 so I made a throat cast. The throat on mine is exactly SAAMI spec. For my use that is a very short throat. But, if using bullets like the Berger 155's, the throat is almost too long. When seated to lightly jam (where these Bergers are best) then the bullets are seated out long.

IMHO, the reason throats seem 'long' is due to the extended range ogives used these days. Makes for a lot of bullet far into the throat.
