I've been researching barrel length for 7mm rem mag rifles and its affect on velocity. I've seen that most factory ammo ballistic charts are developed thru 24" barrels, which shouldn't allow all the powder to burn, as I understand it. So I'm wondering if there is a faster-burning powder for 7mm mag handloads that will "get all the work done" in a 24" barrel?
