TAC, like H335 and A2230 work wonderfully well in .45-70 and .458 Win Mag with heavy-weight bullets.

Well darn, I was hoping it would be a super powder for my little .356 Winny. I am probably going to be forced into getting a Mod. 71 Win. made into a Ackley improved and necked up to .35 caliber. Then I would have a real romping stomping all around Alaska lever action rifle. Heck ya!.

Tac is good for a 40gr Nosler in the 223

Roger that . Also the Hornady and Sierra 40 grain

In reading this while sitting on a dwindling supply of IMR4064 & RL15, what might TAC offer me that those two cant? (would be used in a 308 and 338-06 for reference) Anything particular that might educate me regarding the use of TAC in those two rounds?

"TAC, like H335 and A2230 work wonderfully well in .45-70 and .458 Win Mag with heavy-weight bullets."

Please add the .405 WCF to that list.

I did a lot of work with TAC in my 1895 .405 with 400 grain Woodies for Cape buff in Africa.
In the end, the final load had ZERO (0) fps deviation at 48,000 psi and looked and smelled like a clean burn.
So, I packed it in and packed my bags and took this buff in south east Limpopo:


BUT, I did not like the TAC peak pressure spike and switched to VV N133 and replicated the velocity with a peak pressure of less than 40,000 psi.
This allowed me to shoot the same velocity load in my .405 DR and tuned it to regulate just fine.

TAC pours better than 4895 (either) and has a better attitude than H335. So I'm not surprised at all it works (really well) in both 223 and 308. For the 356, you're probably not going to get into its pressure curve. All powders have a favorite peak pressure and if you don't get there, you're wasting gas.

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.
