[QUOTE="MagnumManiac, post: 891091, member: 10755"] I just don't know if my results will 'track' in another cartridge, but they are very similar in capacity and barrel lengths and compare well. I have had magnum rifles in 24", 26" and 28", and too be honest there is really very little to be gained by trying a very slow powder to increase performance, chances are that you will only get less barrel life and an extra 100fps is not anything to write home about. I also found that whatever powder produced the highest velocities in the shorter barrel, also produced the highest velocities in the longer barrels, so I don't feel that trying a super slow powder will achieve much, but I have to say that I have had my best results in a few cartridges to date with RL25 and Retumbo, which run very similar charge weights and produce very similar velocities in equal barrel lengths, quite a bit faster than some traditional powders, so it just may be that it isn't too slow for your application. Either powder have produced the highest velocities in the following chamberings, 25-06, 264WinMag, 270WeatherbyMag, 300WinMag and 300WeatherbyMag. I have never owned or loaded for a 7RemMag, sorry.
