[QUOTE="Fiftydriver, post: 224983, member: 10"] You have gotten pretty good information on this subject. There are basically three catagories of chamberings in the big 338 cal magnum family. The top run are the rounds based on the 408 CT parent case. These include the Chey Tac, Sniper Tac, Big Baer, Extreme and my Allen Magnum. Those are listed pretty much from slowest to fastest when all are loaded to same pressures. The middle three are basically identical in every way so there is really no different between them. The Chey Tac is around 100 fps less then the middle three, the Allen Magnum would top out 100 fps more but all are in the same class, VERY IMPRESSIVE. Your basically looking at 3200-3400 fps. The next step down includes the 338 Lapua Improved and its variations including my 338 Allen Xpress, the 338-378 Wby and the 338 Kahn. These rounds will get you into the 3000 fps class with 30" barrels. The next step down includes the 338 RUM, 338 Edge and 338 Lapua. Here your looking at 2750 to 2900 fps in 30" barrel lengths. It all comes down to a few pointed questions. These are the ones I ask my potential customers when they tell me they want a 338 Allen Magnum: 1. How far will you realistically be hunting or shooting? Many want to be able to shoot or hunt out to 2000 yards but few have a real need for that because of the area they live. 2. How heavy of a rifle can you live with for your type of hunting and shooting? 3. How much will you be shooting this new rifle? 4. Are you set up to handload your ammo? 5. What is your budget for this project? Everyone has one so be honest with yourself. After getting this information its much easier to recommend what would be best for you and your needs. If your going to be shooting from 0 to 800 yards realistically, there is really no need for a 338 based on the 408 case other then just having one of the biggest 338s out there. As far as the 338-50BMG, its really a dead stick. Not practical and the 408 CT based rounds will get surpisingly close to that chambering in performance and offer practical barrel life and will not require a BMG receiver to build on. [/QUOTE]
