Home Forums Hunting & Shooting Ask The Gunwriters Ramshot TAC

I use TAC and a magnum primer in the .358 with 250s.

Yep, it works.

Just looked through Gun Gack IV, Rifle Load That Work, and found these other TAC cartridge/bullets combinations that performed well in one or more rifles, providing both high velocity and small groups:

.17 Remington Fireball, 20-grain bullets.
.222 Remington, 40-grain bullets.
.300 Savage, 125-grain bullets.
.35 Whelen, 225-grain bullets.
.350 Remington Magnum, 225 and 250-grain bullets.

TAC, 358, 180 Barnes ttsx is a killer combination.

i really like how well i can volume load with Tac powder , have been working with a 6 BR load with Tac powder now so far not as good as Varget powder for accuracy yet ?

TAC is great for those.

It's a ball powder.

Mag primers and lean on the gas.

Yep!

And unlike many "traditional" ball powders, TAC burns a LOT cleaner with maximum loads.

I have found tac to be pretty temp stabil as well

I know that is true, but I've used TAC in the 30-30, and it's pretty clean there too. Not high pressure.

Using TAC in my 300 Savage with Hornady 150gr SP Interlock...

I used a max load of TAC with a 150 grain TTSX in a .308 in really hot weather in Africa and had no problems. Based on that it seems pretty temperature stable.

my good friend Greg the machinist /barrel man shot a bench rest shoot in Missouri a couple of weeks ago and shot well there ,Greg is hoping i figure out a good load out with Tac powder and said he then will probably switch from Varget for easier loading ammo. > i got to also mention this for the guy`s that clean their rifles a lot , Greg went down there with 2 rifles with clean barrels and ready to shoot in match and shot one different rifle each day sometimes he only shoots one for the whole weekend, one is a 6 BR the other is a blown out kinda 6BR .when Greg goes too these matches he never cleans his rifle barrels or barrel tell he gets home rather he uses the same rifle for both days or not , thinks some guys clean their rifles to much , Greg won the second day won some matches and won best group for the day too with his dirty on cleaned rifle barrel he used that day.

It is very stable, but like all powders, pressures and hence velocities do tend to increase at temps over around 80 Fahrenheit. How much, of course, depends on the temperature, but in temp-stable powders pressure doesn't increase as much as with "standard" powders.

TAC was the first Ramshot powder I tested in real cold. My standard test is to work up a load at around 70 degrees, then when the temperature drops during the Montana winter, retest at zero--with the rifle and ammo both chilled, just as they would be in hunting.

I tested it in a very accurate Kimber .223 Remington, and the load averaged exactly the same velocity at zero as at 70, which is the only time that's ever happened with any of my cold-tests. There had to be some luck involved, as even when re-chronographing the same load during the same range session, a string generally varies a few fps from other strings.

By chance, is TAC a rebranded powder with another name that might also be available?
Like A2230 and Xterminator?

TAC has never showed me any love I've tried it in my 35 Whelen (200 TTSX) and .308 Win (150/155 gr).

Not in North America. Have heard it's sold under another name in Europe.

What primers and charges did you use?

Maybe not considered "high" pressure but if at or near max that's all that matters for that particular cartridge

Does Tac work in the 308 service rifle with 168's?

this is the powders I have on hand. I use IMR 4350
