[QUOTE="FURMAN, post: 1725796, member: 26535"] Yes it is physics. I don't understand your question??? Nobody I know who has a clue about long range shooting picks a bigger cartridge to use the same powder charge as a smaller case. That is not how reloading for accuracy works. Bigger cases are chosen for more velocity or the same velocity with less pressure(better brass life). Even with that in mind you do not get to chose where a particular powder/bullet combo will have the best accuracy velocity wise. That is why we have to do load development. It sounds like to me you are trying to do a backwards comparison. The larger the case the faster it will go at the same pressure with an appropriate burn rate powder for the cartridge. Larger cases typically are less efficient. We can play this game both up and down. The RUM is faster, wait the 30-378 is faster. Let's go down. The 300 WM uses less power to do almost the same, wait the 300wsm uses even less powder to obtain slightly less velocity but is more efficient... The fact is the 300 WM, 300 PRC, and 30 Nosler are three of the most comparable cartridges, capacity wise, available. The fact is their performance will land exactly inline with the capacity. I see no need to pick the weaker performer when the powder burned will be very near the same. I can't tell if you are trying to learn or just troll? I have shot all three cartridges extensively and the 30 Nosler outperforms the other two period. If you are looking to save those extra couple grains of powder or the 50ish rounds of barrel life then get a smaller case. I would have to ask where does that stop? like I said is it 300WSM, 308win, 30br??? [/QUOTE]
