I would appreciate all opoinions and load info on this subject. My usual loads consist of IMR 4350 and H4831 and I usually ignite them with a mag primer.
Are they better, maybe, depends on what you consider better.
If you are "satisfied" with your loads and how the perform then you can certainly leave well enough alone.
If you are like me and enjoy reloading and experimenting with components both new and old, the go for it, get some new powders and some new bullets and experiment away.
