Exactly.
But many handloaders often keep using what's worked for them for many years, either because they never try anything else or they bought a lot of it.
Once in a while one of these guys actually tries something different and sees the difference. I have a couple of friends who claimed for years that XYZ cheap bullets were just as accurate, explosive and flat-shooting on prairie dogs as those more expensive plastic-tips. Then both of them tried some of the plastic tips, and changed their minds. As soon as I tried Benchmark and Ramshot TAC in the .223 my remaining H335 went unused. And nowadays there are even more clean-burning suitable powders.
