Hey anyone have info on the RamShot TAC powder?
 
Is it any good?
 
What about grouping?
 
What bullets did you use?
 
Will it work good in both .223 & .308
 
Friend suggested I try some figured to ask and see what the experience here is
 
THX

TAC works phenomenally for .308.

The first topic talks about bullet selection. But just an FYI my Colt with a 1/9 likes 50gn VMAX and 52 gn HPBT.

Just rechecked yup the Bushmaster has a 1/9 I have not ever bothered to shoot for accuracy with it just went out and plinked with it but have decided I rather go back to accurate shooting in my centerfires - the plinking I will just the old .22 LR
 
I shot some 62 gr that seemed to group pretty well - never really checked what 50 - 55 gr would shoot in it.

tac works real good for heavy 223, and light 308.

75gr bthp 223 24.2 gr varget-2650fps 20" douglas
"""""        26.5 gr tac-2850

i prefer varget because it's not remotely temp sensitive, and tac is.

a buddy uses tac in his 110vmax load and getting 3350fps 20"sps

i'm getting ready to try rl-15 and 178 amax, but varget/178 cuts 1 ragged hole. but it's a bit slow, hoping 15 give a bit more velocity.

but varget will work with just about anything

I use Target for both 223 and 308 and it works exceedingly well.

It produces comparatively low muzzle flash and is probably the cleanest burning powder I have seen to date.  It also meters really well, so with 223 I switched to it exclusively and, pending some more experimentation will likely do the same with 308.

With 223, I load it with 77gr SMKs to 5.56 pressures.

Wit 308, I load it with 155gr SMKs.

TAC.

I was thinking TAC, but my fingers must have combined TAC and Varget into Target.   I switched from Varget to TAC.  Both worked well, but TAC meters much better and is cleaner.

Hmmm the plot thickens - well as soon as my scope gets here so I can go out and shoot the rifle it seems from what I have gathered I have about 3 powders to load and compare.
 
I appreciate everyones thoughts and input.

TAC is a fine powder for both .223 & .308 - using it about maximum velocities can be obtained with .22 bullets in the 50-55 gr range and .30 bullets in the 150-155 range. It is a double base (has 8-10%) nitro glycerln content ball powder that measures well enough so weighing each powder charge is a waste of time. TAC has a higher density than Varget and fits well into cases so no powder compression happens.
 
As good as TAC is I think Varget would be more popular for long range shooting because of its temperature consistency giving more uniform velocities. PALMA shooters like Varget.
 
Other .223 & .308 powders worthy of consideration are IMR & H 4895 and the olde but short-grained IMR 4320. This is somewhat slow for the .223 but works well in the .308. IMR 8208 should work in the .308 with 150-155's and is a good .223 powder having a wide range of .22 bullet weights. If you can find it another olde powder is IMR 4064
 
For years I used H380 with 168 gr Hornady hpbt bullets in the .308. I used 44 grains for 200 & 300 and 47 grains for 600yds. That was a long time ago and I understand that the new lots of H380 are slower. At one time there was a H375 powder. Velocities with the 44 grain load were only about 2450 but that was enough for 200 & 300 yds.
 
I have started looking at Accurate 2495 & 2520.

Ha yup 4064 & 4320 -  have used a ton of that stuff eons ago - have some of the 2520 loaded up to test and have a pound of 2495 to test also.
 
have some TAC to try also.
 
THX for the info

I use varget for 223 and 308 and my only complaint is that it doesnt meter very well. I have not chronod my loads.
 
223 60vmax 26gr varget  shoots dime size (rra varmint 16'' 1/8 twist)
308 168amax 44.4 varget consistently under 3/4 (sav 24'' 1/10 twist)
 
I would like to try somthing that performs in both cals, meters better and is available. Varget is always out of stock at my local stores.

I've really liked TAC, so far.

I rigged  a very long drop tube to my Uniflow because of Varget- crunch crunch loads for everything I shot.
Varget got scarce and I discovered TAC for 5.56. I get speed with reasonable pressure and it burns clean and flows/meters well. It's also usually less expensive than other powders.

Having said that- haven't been able to find any since December, but have ample H4895 and Rel15.

Yes, I've used IMR4198 for at least 30 yrs in .223 for lighter bullets. It is a very long thin extruded powder, but cuts easily in powder measures. IMR 4198 is very efficient and often requires a lot smaller charge than other powders to reach velocity.
You should be able to find load data for IMR4198 on the web. Often, Hodgdon powders work better for me than IMR equivalents, but IMR 4198 works better for me than the H variety.

Curious if there is a correlation between burn rate and barrel length - assume there is but never gave it much thought till recently.
 
Thought??

Have not, but I will be trying it soon. Varget has worked exceptionally well in my .223 bolt gun with up to 69gr. SMK's.  

I use IMR 4895 in my AR with 75gr Hornady's with mild success.

I like W748 in 223 w/ 62 grn. AR 1/9*, 30/30 w/ 170 grn, 308 & .30/06 w/ 150  grn.
 
R15 has worked well for me in 223 w/ 68 grn. Horn., AR 1/9*. I like R15 in 308 as well.
 
I've used IMR4198 w/ 52 grn.HP in an AR 1/9*, worked good.
 
Their really are a number of established powders, too include TAC , let alone new offerings that will get you up the hill.
 
* All references to AR were fired in 20" bbl.

Another worthy powder for the .223 and also the .22-.250 with light bullets, like under 55 grains, is IMR 8208. I have used 8208 with both and right now I am using 35 gr 8208 with the 53 H VMax in the .22-250. This load is near max with the Hodgdon data and somewhat over what the Hornady manual has.
IMR 8208 is promoted as more temp. stable than various ball powders and meters better than Varget, 8202 is a fine-grain single base powder.
 
The Hornady manual lists some speedy velocities using 8208 with 125 & 130 bullets in the .308W, if you like light bullet .308 loads. Hornady also lists some reasonable velocities for 150-155 using 8208.
