For example, if a rifle shoots well at a 2.80” OAL, what benefit would be gained loading .02” off the lands to 2.86” OAL? Can the small gain in case capacity net a faster velocity within similar pressures using a bit more powder to take up space? I’m assuming this is the same principal just on a smaller scale between a .308 win and a 30/06 or a 6.5CM compared to a 6.5prc. Similar pressures net more velocity in the larger case. It just takes more powder to get it there. Am I on the right track?
