[QUOTE="Fiftydriver, post: 216763, member: 10"] In a rifle length barrel, there is NOT WAY, that when both are loaded to the same chamber pressure with the same bullet weight that the 338-284 will come anywhere near what the 338 WSM can produce. You do not get velocity from magic, like engines, you get increased power only from adding cubic inches or increasing compression ratio or in the case of rifles, chamber pressure. The WSM will easily handle any pressure that the 284 case will handle. If you want to pull the case design card, to be blunt, thats crap comparing these two rounds. Simply put, if loaded to the same pressure with same bullet and barrel length, the 338 WSM will EASILY add 100 fps to the 338-284. Those loads you see that show the 284 based round 100 fps over the WSM are either loaded WAY to hot which often happens with wildcats or the 338 WSM is very underloaded. I have an XP-100 handgun chambered in 338 WSM. It will drive the 200 gr Accubond to 2750 fps in a 15" barrel!!!! [/QUOTE]
