There's a good deal on TAC going on at Powder Valley right now. $77.95 for 8 lbs.
They're also having a special on Hornady bullets.

Thanks a lot! And just when I was trying to stop stockpiling components..

Just a quick note on the TAC powder. I neck sized, and chamfered some new Winchester .223 brass, primed them with CCI-450 primers and loaded 5 rounds each with 26.0, 26.5, 27.0, and 27.5 gr of TAC and seated a Nosler 50 gr Ballistic Tip to an overall length of 2.26". This afternoon, I shot each of the loadings out of my box stock 700SPS Varmint. The velocities ranged for 3344 fps to the max load at 3463 fps. None of the 5 shot groups were larger than an inch at 100 yards and the barrel seemed pretty easy to clean. This is good stuff, particularly with the 50 gr bullets. I am going to grab a couple of kegs. Might as well grab some primers, too. Since they can ship them together under 1 hazmat charge, and primers are in short supply locally.

Thanks for the info guys.

TAC was designed for the 5.56 and heavier bullets (62 - 77 or 80 grains).

I use a lot of it. It is about the cleanest double based ball powder that I use.
