That would be my guess as well. TAC (like many modern powders) works most consistently with pressures around 60,000 PSI, or even a little higher.
Interesting, and I've read that opinion from you about most modern powders. Seems entirely logical. But what about the 30-30 as you mentioned as cartridges loaded? I need to load for a 1952 model 94 that's never been hunting but will go next year. Have 150 gr Hornady round nose on hand and TAC. But looking at pressure levels for the 30-30 it doesn't seem to carry the logic of TAC powder. Does it simply work because it works? Starting from scratch what powder would you choose for the 150 Hornady, not necessarily from the standpoint of max velocity but as a consistent and clean burning propellant. thanks.
