Anyone using TAC in a .308 with 175+ class bullets? I'm running outta' room with '15, and have room to go in the pressure spectrum so to speak, so this powder caught my eye.

I've heard some guys say it's too fast for the 308 and I'll see quicker chamber and barrel heat, which is a concern as this rifle is a long string of fire type rig.

thanks all!

Cann't answer regarding 175's, but I'm running it behind 150 grain accubonds. In a 22" tube 46 grains gets me 2890 fps and accuracy is even better than what I get with Varget. It's also alot cleaner burning than Varget. YMMV

Anybody blasting TAC?

I use it for 175s and 180s, I just don't know how it works for long strings of fire.

Speeds?

I've used it some with 125-150 gr. bullets in the .308. As said it works quite well and has an anti fouling agent added to it.
Ramshot's Big Game apprently offer more speed with 180 gr. bullets. See their website.
TAC tops out at about 44.5 grs. and 2734 fps. in a 24 inch tube with the SRA 175 gr. MatchKing bullet and about 2621 with 42.4 grs. with the SRA 180 gr. GameKing.
What I noticed is that the sweet spot is pretty specific with TAC. Usually near or at the top end. At least in the .308 and with lighter bullets in the .280. E

Sorry man, haven't chrony'd.

Sir,

Have you used TAC with 165's? I have several hundred Hornady 165gr BTSP, and am trying to figure out whether to use TAX or Varget next.

Thanks,

Ed
