Home Forums Hunting & Shooting Ask The Gunwriters TAC is best for....

I am going to order some TAC to try in a .358 Winchester I just put together. Per Mr. Barness I understand TAC is the bees knees for this cartridge.

What other cartridges does TAC really shine in? I’m trying to decide how much to order.

I've used it for 204 and 223.

It’s solid in the 338 Fed.

Pretty much anything with similar bore/case capacity ratio. 308, several of the smaller "assault rifle" cartridges like 5.56 and 6.5 Grendel, etc.

If you haven't done so, I recommend downloading the Western Powders load data (I think version 6.0 is the most recent). It has good data for the Accurate and Ramshot powders, and will be one of your best resources for using TAC.

.223, .308, etc.

223,222,243,257,260 and other like minded.

I even use it in my 47-70.

Gary Sitton liked it in a 24in. bbl. 30-30

Anything with a 20-30 grain capacity, and .308 cartridge based stuff it excels......

Ramshot has some of the best loading data in the business if not the best and it's accurate too...

Don't know where you got your info but it's definitely a bit too fast burn rate for 243 Win, 257 Bob, and 260 Rem unless you're trying to load very mild loads with faster burning powder. I sure wouldn't be recommending something like TAC as general use for those cartridges.

I have a pound of it that I am going to use to work up loads for my 6.5 Grendel.

I've been using TAC as my "next" powder for .223 load development. So far it's given me the tightest groups of all the powders I've tried. often with 4 of 5 rounds touching in a 5rnd group. But there's always one weird flier that lands about 3" or so outside the group. I haven't determined where in the string it occurs yet. I suspect it's a barrel/heat problem.

2 suggestions:

- double check that nothing is contacting your barrel, especially when the barrel and/or forend flex
- try a different primer. The S&B primers gave me better accuracy in 223 than CCI 400/450. WSR were decent as well.

Also depending on your bullet weight, XTerminator is worth trying as well. It's just a hair faster than TAC, and gave me a little better accuracy and a little more velocity with bullet weights from 50-69gr. Stick with TAC for the heavier bullets. For the really light stuff, 40-45gr, Xterminator was definitely better. Same powder is also sold as AA2230.

What are some of your best loadings for Xterminator/2230? I've got a bunch of it to use up. Do you have a "standard" load that works in everything including ARs?

Good .223 powder that flows well through a measure, but I've usually seen slightly better accuracy with H4895, which doesn't flow as well through a measure.

I've use quite a bit of it in a match barreled AR with great results. My 223 M700 ADL slightly prefers Benchmark but does almost as well with TAC. My well worn 308 doesn't like it as well as several other powders. I've been meaning to look into it's use in the 250-3000 but right now H4895 and Big Game take top honors in those rifles.

I use TAC in my .350 Rem mag, .308 and .358 Win. Good stuff.

My 788 in .223 loves a 50-grain V-Max pushed very hard with TAC. Just damn near as accurate as my .222, another 788.

I burn a lot of TAC, because I've used it with good results in a bunch of cartridges, including the .204 (where it's my most frequently used powder), .221 Fireball with 50-grain bullets, .222 Remington, .250-3000, .30-30, .303 Savage, .300 Savage, .338 Federal, .338 RCM, .358 Wincheser, .350 Remington Magnum and .35 Whelen.

Oh, and the .223 Remington and .308 Winchester! Though I've found different .308's vary some in how well they react to it.
