[QUOTE="hemiford, post: 1258889, member: 72104"] You are exactly correct. Two cartridges with the same charge weight need the same barrel volume to achieve the same expansion ratio. Only then can you compare ballistics and pressure curves. From this, it's clear that a smaller caliber needs a longer barrel. Kind of a pet peeve of mine that some people have no problem comparing a 308 with a 26" barrel to a 300RUM with a 26" barrel, for example. [/QUOTE]
