See several posts naming Superformance as worst.
Not my best powder in everything applicable, but now and again there is something else to see...
7x57, 160 Sierra BTSP, F210, 0.1 off lands, 48.5 gr. 100 yds, 5 shots.

I found out a long time ago that the original XMP5744 had to be loaded to ~ 25 kpsi before it would burn clean. These copies are probably the same. It was good in the .30-06 with heavy GC bullets at hunting velocities. Good in the .35 Remington 200 grain at 1950 fps. Not so good elsewhere. I still have plenty of it, but don't load those cartridges anymore.
Some of the old timers on here may recall Herters. When I first started reloading, there weren't many shops in my area that sold reloading stuff, so Herters was the "go to" place to stock up on supplies. I don't recall ever getting any Herters powder in the "worst" category. I sure do miss those days. I'm glad I kept their catalogs.
I like trail boss! Send it to me.lol. Never got good groups with anything using H380 accept for low powdered 90 grain Seirra FMjs in my 243. To be honest trail boss never grouped worth a darn in anything accept for my 45 colt vaquero. Everything else horrible groups. It's a tac driver in my vaquero with similar 22 wmr recoil to boot.
