I think so too. Necessity is often the mother of invention. H4198 has been very good and for so long, tons of people had never tried anything else. That's for sure not me. I enjoy testing different combinations, loads, powders, even cartridges. Sometimes it takes a long while to discern if one is better than the other, when you find something else that works and sometimes...it's even better.
I found a load using a blend of AA2230 and AA2460 in my 6 Grendel with 80's that might be the best load of all in it. I found it because 8208, Benchmark, h4895...several that I knew were very good but they all got so hard to find. I had some of I think all of those but I didn't want to run out without a good plan B, C and D! Testing stuff is how we know things. And remember, it was a blend, not just trying one or the other or even both...but thorough testing is how and why I found it.
