I favor IMR 4895 for that bullet weight.

I have been happy with Varget, and it's vary temperature insensitive, BL-C2 is another powder I like.

RL15, Varget, H4895 or IMR4895, or IMR4064. I have the same rifle, and settled on RL15 after trying these. They all gave great results, but I am loading the 175 SMK instead of the 168. Good luck!

Most 308 will eat any powder made for them.

IMR 4895
Varget
Benchmark
RL 15
RL10X
Win 748
Win 760
VV N140, N150, N540, N550
and bunches more

Soon to be released RL17 suposted to best RL15 by at least 200fps or more.

The 308 is not very picky when it comes to powder every powder I have tried in mine has produced 3/4" or better groups at 100 yards. Not good enough for me but I am getting there.

IMR4895 or IMR4064 are both good. Lots of others too.

It's not a picky cartridge like some, which makes it good to reload for in that respect.

I really love IMR 4064, Varget, and IMR 4895. I Recommend against using BL-C(2) because for me it was so dirty...

when i started reloading 308, sierra listed R15 as their accuracy load. it lived up to that in my experience.

however, i just switched to lapua's scenars with VV N540. So far, I'm quite pleased.

Any of the medium burn rate powders work well in the 308. The slower powders are not as efficient and will not give top velocities. Check out some load manuals or the online load data bases that are available. Hodgden.com is a good one.

I've been using Varget, but will move over to Ramshot TAC when I burn thru my last lot of Varget.

I like H335 for hunting and IMR4895 for targets.

I like Winchester 748 and 760.
Both meter well through my powder measure and are very consistent, which leads to pretty good groups.
I started with 748 but I've found that my rifle works fine with 760 and it's easier on the gas system, so why not?

I've used both IMR 4064 and 4895 with excellent results. You can't go wrong with either.

With the varing temps in my area, Varget seems to be the best. Five rounds expanding the same hole at 100 yards can't be wrong.

I tried 748 and wasn't too impressed, but it was my first shot at reloading. I switched from 165g sptizer to 168gr BTHP, (both hornady), and 41.3gr of Varget and found the "sweet spot" for shooting my AR10B. I'm sticking with Varget.
BTW: I did work up my loads using a bench tie down, with 5 rounds of each load.

42 grains IMR 4895 and Sierra 168's have been a benchmark load forever. If your rifle won't group that there's usually something wrong. Ditto 41.5 and a Sierra 175. OAL 2.830"

Varget and RL15 have a stellar reputation in the long range shooting 175 and 180's. My hunting/F class load is 42 grains RL15 and a Nosler 180 BT.

I like H335 for huntingMe, too. I did some head-to-head comparisons of Varget and H-335, and my H335 loads came out SLIGHTLY more accurate. Haven't seen any issue with temperature variance...yet...

But that's just my rifle and my load for 150gr. bullets.

i found Ramshot Tac an excellant powder for .308win using 150 gr to 168 gr bullets works well in semi auto G-3 and Rem 788

Win748 or H380 or IMR3031
A method to select powder is to look at the manual for all of the powders for the .308win. Select the powder that uses the least charge weight to achieve the highest velocity, to get the most shots per pound of powder. Those powders that give the lowest charge weights to get the 2400-2750 fps will give more shots per pound.
H380 was always the #1 choice for benchrest accuracy. Hodgedon stopped making it for a long time but demand and inquiries for it prompted Hodgedon to start making it again. Win748 took over as the preferred powder for the .308win after Hodgedon discontiued H380.
Varget, Vitavori and some others have since some along and also give consistently accurate shooting in the .308win., but are more expensive than the Win748, H380, 3031, 4895, BLc2.
The.308win. is not persnickety about the powder used in it. Some powders do work better than others. What you can afford to shoot in it also affects your choice.
Best velocity for whitetail deer using the .308win. is around 2500fps. with 165 or 168gr. bullets. Not too fast, nor too slow to avoid wounding the animal and it escaping nor causing excessive meat damage. I lost six deer using 150 grain bullets. I was using a Remington 742 1/10inch twist, which was accurate with 180grain bullets. The 180`s were tearing up too much of the deer. I was throwing away neck, both shoulders and both ribs, getting only the back and hind quarters for the freezer. The 150 grain bullets were not accurate. I flipped the Remington 742 for a Browning Abolt 1/12 twist. More accurate. 180 grain bullets are better for elk. I still get meat loss with the 165`s but not 50% of the deer.
42grains - 42.5 grains of Win748 gives .5 m.o.a. accuracy and velocity spread from 2500 - 2518 fps. (42grains) with my rifle.
The .308win. is a fine deer/elk hunting caliber.

H4895, so far have had 2, five shot groups at 100 yds in .4in, most are .6 to 1 in groups.

I tried Varget, H4350, WW 760, RL 15, and found all pretty good. But WW 748 kept giving the tightest groups. So it's my .308 powder.

I've read a couple of articles about the Remington 700 SS 5R Milspec. The accuracy load seems to be 175 SMKs with 42.0 grains of Varget, OAL 2.800" - though each rifle is, of course, unique. That's probably a great place to start.

gindeep, you have lots of answers in the posts above. My experience is that I have to try many powders to discover how each of my rifles reacts. None are the same. Over time you collect 1 pound bottles of many, many different powders. That gives you the flexibility (and fun!) of finding the right powder for your rifle.

I tried H4350 yesterday just for laughs and came up with a good load just before it hit Max. Normally though I use R15.

There is no Max when using H4350 in a .308. You simply cannot get enough powder in the case for a Max load.

I go between Varget and IMR 4895 for 150gr bullets and IMR 4064 for heavier. I have a few other powders for 308 and 30-06 that I mess around with, such as BLC2, Reloader 15, and 4350 but I keep coming back to these three.

Cheers.

rbernie, why the move from varget?I'm annoyed a bit that I've not noticed the vaunted 'temperature insensitivity' in my chrono sessions and that each lot seems to be a bit different. More importantly, I can get TAC for about 60% of the price of Varget.

If I'm going to have to deal with 'average' lot-and-temp variances, I might as well do it cheaply. :)

Reloder 15 will give you the most speed (power) with bullets weighing up to 178 grains, which is most important with hunting rounds. I use this powder in my 308...for long range loads, it works great...its not temp sensitive, and lot to lot consistency is good.

Varget has a problem with lot to lot consistency...and it will not produce as much speed as RL 15, even on a good day.

IMR 4895 deserves an honorable mention here also.

Since I have a Remington 700 tactical .308 with a 20" heavy barrel, I'm going to load with H4895. Its faster than Varget in terms of burn speed, with the short barrel, I'll get a complete burn.

I have recently switched from Varget to RL15 for my Steyr SSG (25.6" heavy barrel 1-10 twist). The RL15 loads seem more consistent in this rifle pushing 155gr Matchkings, and 175gr Matchkings. Either Varget or RL15 under the right bullet will deliver sub MOA groups, but I find RL15 to cut that down even further.

My last good session with this rifle produced a five shot group well under 1/2 MOA with 155gr MK's in Nosler brass. Four of the rounds went into a group that measured about .15 MOA, then like a moron I questioned the group and put on two clicks down on the turrets and was rewarded with another impact about 1/3 MOA down from the rest of them. :banghead:

I will probably be flamed, but I think Varget is over-rated.

I do not believe it meters as well as some other powders, and I therefore find more variation in the weights of the charges. If you are going to weigh all charges by hand, then I guess Varget would be OK.

I have switched over to Win 748, and have found it will do everything Varget will do, plus it meters better. I have switched to using Win 748 for all my 308 and 223 reloading needs, and have not looked back. Its an excellent powder.

My newest 308 (an SPS Tactical) also has a 20 inch barrel...I still get the best speed and accuracy with RL15.

According to QuickLoad...the only powder that will give a complete burn AND good velocity is IMR 3031.

The next best for 100% burn is AA2520...

RL15 burns 99.8% of a 45.5 grain charge in a 20 inch barrel...and gets more velocity than either of those mentioned above.

This is based on my load...with a 165 grain Nosler Ballistic Tip. This is not a "virtual" load...I have chrono'd it and QuickLoad was pretty darn close...QuickLoad predicted 2,614 fps with 44 grains of RL15...my chrono said 2,635 fps. (45.5 grains is MAX...at well over 2,700 fps from a 20 inch barrel)

44 grains of RL15 was the most accurate load I tested out of several different powders.....It produced 300 yard groups measuring slightly less than 1.25 inches across the widest points. (around .3 MOA)

Have the same rifle (5R)...tried different powders but RL-15 gave the best result. 178 grn A-Max, Lapua case, CCI BR Primer. Surprisingly, 2.800 COAL.

Nope, not looking at any manual. I have used and know H4350 powder in a .308 Win case, and you simply cannot get into a maximum pressure situation using that powder in that case.

Every time I read how temperature insensitive these "EXTREME" (nice buzzword :rolleyes:) propellants are supposed to be, I always wonder if the conclusion is from actual testing of the same load/same lot across a wide range of temps, or if it's nothing but parroting Hodgdon marketing buzzwords?
