[QUOTE="Weatherby Fan, post: 1914833, member: 29953"] So many variables to go along with “cartridge efficiency” from primer used to powder, barrel length, just the tightness of the barrel bore, throw in a little neck tension can even change things up. My brother and I have the exact same rifles and cartridge and his shoots 80 FPS faster than mine on average with the same handloads or factory ammo, we even used the same box of factory ammo and had the same result, only mentioned this as to show variables in two of the same rifles and cartridge never mind two different cartridges with similar case capacity. with that being said for example I would take the 300 PRC over the 300 Win Mag everytime just based on cartridge design, no belt, steeper shoulder angle, longer neck etc, is it more efficient in that design ? that’s for someone way smarter than me to figure out !
