What reloaders say about it
Unverified community anecdote. The following is a summary of what handloaders report in public forums. It is not manufacturer information, it has not been tested, it may be wrong, and it contains no load data by design. Treat it as colour, not guidance.
TAC has a quiet but consistent following as a well-metering ball powder for .223 and .308 bulk and hunting ammo. Notably, its reputation for temperature sensitivity is contested — at least one poster who ran their own cold-to-hot testing reports being surprised at how stable it was, which other commenters treated as counter to the received wisdom.
- ball powder, reported to meter excellently
- reputation for temperature sensitivity is actively disputed by users who have tested it
- favored for bulk .223 and hunting-grade .308
- described as good value
Availability: Generally described as findable; not one of the chronically scarce powders.
Reported cautions:
- 'Everyone always says it's temperature sensitive' — the community itself flags this as folklore that may not survive testing. Treat both the folklore and the rebuttal as anecdote.
Consensus level: commonly mentioned. Drawn from thread 1, thread 2, thread 3.

Verify the charge, not just the recipe
Good data gets you a safe starting point. It does not tell you what actually went into the case on stroke 340 — a bridged measure, a double charge, a squib. That is what an RCM Laser Powder Check is for.
