TAC vs X-terminator

7047 Views 17 Replies 9 Participants Last post by  paulosantos
So I have allready bought some TAC but thought I would ask what was the diffrence, and how much luck yall have with the TAC?

I bought TAC because it seemed like a all around good powder to use in my 6.8 extreme, 6.5 Grendel, and 5.56. I didnt what to have 3 diffrent powders floating around when I could condense.

Anyways if this is a terriable powder let me know that as well.

TAC is pretty good and will actually work very well for all three. By the way, you suck for having all 3 calibers.:D:D:D

For the TAC powder, just start by using the X-Terminator Powder recommended MAx and just add 1 Gr. and that will be your max.

Since you have the AR15Performance Barrel:
For the 90 Gr. bullets: 34 Gr. of Tac (If you can actually stuff that much in there).
For the 110 Gr. bullets: 31 Gr. of TAC.
For the 115 Gr. bullets: 30.5 Gr. of TAC.

Look for pressure signs and you might be able to go higher.
Is there a preference--Tac or X-terminator? I'm about to pick up a few 8lb kegs, and I want to get it right the first time. I'm going to make a go at major PF in 3-gun with heavy 130 / 135 grain bullets out of a 20" barrel.
For the 6.8SPC, you will be better off with the X-Terminator Powder.
Tim, I just ordered an 8LB jug of TAC and I will be trying it again for the 6.8SPC and the 5.56. I remember trying some TAC with my old 20" barrel and with 33.5 Gr. of TAC it was almost the same velocity as 32.5 Gr. of X-terminator with the 90 Gr. bullets. When I recently spoke with the Powder guy from Ramshot/AA, he said to take the reloading info for the X-Terminator and add 1 more Gr. of TAC and the velocities will be similar. I think TAC is very good powder because it is very cheap and it is pretty accurate. It may not produce the highest velocities, but it is a good powder to use.
So using this TAC I bought is 1 moa going to be achievable? Yall got me all worried that I bought the wrong powder. I got a 8lb so its going to be a little while before I move on to something else.

All I want to do is shoot moa with all 3 guns using the same powder.

Tim_W who is CF? The guy with experience with the 6.8 and 6.5?
It is good powder. It should be able t shoot MOA.
I have been using Tac in my 5.56 and .308 loads. I am looking for a place to start with my110grVmax, 12.5 inch WOA spc2 barrel. Does 29gr sound right? I appreciate the info sharing.
29-30.5 Gr. should be good.
