[QUOTE="Timber338, post: 1097893, member: 33822"] I have a 338-300 wsm on a M70 short action and a 24" barrel. I really like the cartridge and it certainly is efficient. In a long action with a longer 28" barrel properly throated for a bullet like the 250 Elite Hunter you could make a legitimate 1000 yard hunting rifle and get velocities in the low to mid 2700 fps range, maybe even up to 2800 fps. My rifle is not set up for long range but I was pushing the 250 accubond to about 2650 fps. If you are looking for efficiency (as in ratio of grains of gunpowder to fps) it doesn't get much better. The question I would ask is why go with the wsm wildcat when you could go with any of the bigger cartridges and get more velocity? The RUM is going to get 300+ fps more velocity with the same bullet in the same rifle. My 338-300 wsm is set up as a lightweight backpacking elk rifle and I went with the 338 RUM as my dedicated long range hunting rifle. Brass for the RUM is not all that hard to find and I can load any bullet into my Wyatt box including the big 300 grainers. Anyways, in the right rifle a 338-300 wsm could be a great long range rifle. I would be happy to pass along load data and any other info if you have any particular questions. [/QUOTE]
