[QUOTE="benchracer, post: 2059471, member: 22069"] The 338 Win Mag will do its best work with 250 grain bullets and lighter. The 250 Berger and 230 ELD-X are both excellent choices. My Ruger 77 MKII is chambered for 338 Sherman. It runs 230 ELD-X, with an OAL of 3.425, at just under 2900 (which is the accuracy node, not max). With the Berger 250 EH seated to 3.555, the accuracy node comes in right at 2800. It is capable of running a 285 ELD-M between 2650 and 2700, but the practical gain over the 230 and 250 isn't worth it. There is no magic to any of these loads. Matching the right powder to the right bullet is the key. With the right powder, your 338 Win Mag should do anything my Sherman does and is likely to be able to produce +100 fps vs the Sherman with a given bullet. The Sherman case (modified .280 Remington) does not quite have enough capacity to utilize RL-26 efficiently. I believe the 338 Win Mag would be about right for that. Vihtavuori powders, such as N560 and N565 might also work well. My advice is to work with the rifle(s) you have and patiently search for the right powders and bullets. When you have them in hand, take some good measurements of OAL to the rifling, with each bullet you want to use, and do some testing. You are likely to be surprised at the results and likely to find that your performance goals are within reach, using the rifles you already have. If your testing shows promise, buy the highest quality brass you can find and develop your final loads. ETA: If you don't already have them, buy a good chronograph (such as a Magnetospeed) and a copy of the latest Quick Load software. Those two items, along with some reloading components and some range time, will take you further for your dollar than any of the factory rifles you have mentioned as being under consideration. Once learned and refined, the same techniques can be applied to your 7mm Rem Mag, giving you some options in the field. [/QUOTE]
