Thread: powder for magnums?

I load for 7RM, I use 2217 for anything up to 162amax, I have had good results and 150-250ft/s improvements with 2225, however I only use it for heavy projectiles, 168+gn.
The way I understand, 2213sc is ok for magnums cartridge with small capacity such the WSM things, 2217 and 25 are recommend to "big" magnum cartridges(please understand with high load capacity), also, yhey are recommended for different projectiles weigh with some exception and personal preferences such as "faster" burn rate powder "good" with lighter projectiles, slow burn rates with heavier projectiles.
As also mentioned here, primers can and will play a big part in the process, select it wisely
Please, fell free to comment and correct me if necessary, I am just a "novice" and happy to learn more and more regards reloading.
