Hey all! I'm looking for a little advice on something I have never tried. I have been hand loading for about 10 years, and have worked up great loads for my .220 Swift, .243 Win, 25-06, and 30-06. I recently purchased a Remington 700 in 7mm Rem Mag and am preparing to work up a load for it. My plan is to try several different powders, working loads up from min to max shooting 168 gr. VLD's. I am then planning to take the most accurate load from these tests and play around with the overall length of the cartridge and see if I can get a bit more accuracy out of it. My question is do you all think this is a good idea, or am I wasting time and money? (Note: I never consider loading a waste of time ) Or, do any of you have a better way to do it? Try one powder and mess with the OAL? Just looking for other's thoughts. I know it took a LONG time to find a load for my 30-06 only changing powders and bullets, but I finally did find a round that shot a hole in a hole.
