I've shot my share of 450b, 5-shot 100yd groups over the years. To date, the 225gr FTX has consistently been the bullet of choice in my two 1:24 barrels. Interestingly, for the time that I had a 1:16 barrel, I could not find any of my previously established 1:24 recipes that it liked. It is now someone else's barrel. Earlier this year, I did test some Brass Lehigh Defense Xtreme Penetrators
Link that set a new high bar for good groups however. While the latter was remarkable, the initial loading were a little hotter than I like to run my AR based rifles, it was just being in the right place at the right time in terms of starting recipe. The 225 FTX has shined bright for many different charge weights for over 8 years.

Reloading results can some times be anecdotal. I tested bullets that started off like stepping in a cow pie, only to wind up being pretty darn good once I found the
Optimum Charge Weight that my specific setup liked. I consider the time spent working up recipes to have high entertainment value as well as a means to an end but that's just me.
