Best powder for .308

Hi all. Just wondering.What is the best powder to use on the .308 to get the best accuracy?I understand that each rifle is a individual and one powder may not shoot the same in terms of accuracy in all rifles.
But on average,which powder may be the best?

I am currently using BLC(2) and it shoots pretty good.It is pushing a 125gr sierra at 3000fps and groups are averaging around an inch or a tad less.Could this best about the best I get using the lighter bullets?.The rifle shoots the 168gr match splendidly. I am striving for 1/2 inch groups at 100yds with the 125gr.(Shooting a Rem700 varmint special)

Thanks for the help and advice
Paul

Oh yeah,to you fellas that replied to my thread on gas powder residue on the cases.I am using this 3000fps load with the BLC(2) and cases are clean after firing.Load must be generating enough pressure to seal in the chamber.
Thanks.

Generally, 125 grain bullets are not considered to be the most accurate in a .308 - unless you go to some custom maker, the 168 Sierra Matchking is the "king" of accuracy. (Though when ranges grow to 1000 yards, some of the best shooters go to a heavier bullet- again, usually a Sierra.)

The standby powder for "match" ammo with the Sierra 168 is IMR4895, but I've had better accuracy out of my M1A using IMR4064.

FWIW, I've read that Federal chose a non-cannister grade of IMR4064 for their Gold Medal match ammo.

Since you're shooting a bolt action rather than a gasgun, you have the luxury of using just about ANY reasonable powder. If the IMR's mentioned don't work well, try something slower . . . maybe if you give Sierra a call at their 800 tech line, they can give you some advice.

AA-2460 From 40.5 grains to 50.0 grains
Remington 9-1/2 Primer

I found this the best combination, but you probably won't get the accuracy you are looking for with the 125, especially since it appears your rifle likes the heavier bullets. Your twist rate may be too fast for the lighter bullets.

I guess I'm a bit of an oddball, but I've had great results using IMR3031 with 165grn BTs.

RL 15 has been myt best all around powder for my .308's and .06.
In my Rem VLS with 125 gr BT's I use 48.5 grs and Fed 210M primers. They clock just under 3000 and group around 1/2" no problem. I have 1:12 twist in the VLS which I assume you have in the varmit special?

I've used a variety of remington and winchester bulk bullets, as well as various hornady match and hunting bullets. I find that the bulk core-lokt's and PSP's work just fine, and are easier on the pocketbook. For powder's I've used Ball(C)2, 2520,2460,IMR4064 and 4320, and Varget. Honestly, I don't think powder type makes much of a difference accuracy-wise.

Paul, In 125 grain I'm using Nosler Ballistic Tips. I'm not familar with the Remington Varmint Special but just guessing that the only dif between that and my VLS is the stock. Anyone know?
I also have a Rem 788 in .308 that groups between 1/2" and 3/4" with that same load and average fps of 2800 but the barrel is 4" shorter. By the way Hornady lists max load with RL-15 and 125 grain bullet at 50.1 but I've only started working with that bullet and haven't pushed it any harder yet.
RL (Reloader) 15 works so well for me I bought a 5 pound keg and my other powders have been pushed to the back of the case. It worked well in my 22-250 also before I sold it.

Paul; Another couple of powders worth taking a look at with that 125 grain bullet are Vihtavuori N-135 and N-140. I have had great success with these with light bullets in both the 308 and the 300 Savage. Regards, Eagleye

Thanks

Thanks to everyone for all the sound advice I have recieved.Looks like I have some work to do in trying to get the 1/2 inch groups with the 125s out of my rifle,but heck,that is all in the fun of reloading.
Yeah Clint,I'd say you are right.The Varmint Special has the 700 BLD walnut stock and the barrel is a little shorter.Probably the same twist as your 700 VLS.
Anyway, thanks to all
Paul.

Paul, I forgot to mention that my Rem 788 has a 1:10 twist and it still did well with that 125 gr bullet. What barrel length on your Special?

Clint,the barrel is 24 inches long.I really love this rifle.I have a 700vs in the 22-250,but there is some really something about the older Varmint Specials to me.It is in like new condition.
Oh,by the way,I have a 22-250 in the rem 788.Shoots great.

best .308 powder

I have a Rem. 700BDLVS in .308 and I shoot 150 gr. Nosler Ballistic Tips and 168 gr. Sierra Match Kings with great accuracy. The best powder I have found for my rifle is RL12. However it is my understanding that Alliant is discontinuing that powder so when my supply dries up I will have to find something else. If you can find some RL12, I suggest you try it.

Best powder for .308? IMHO H335, followed closely by BLC#2 and H380.
