What is your accuracy load for .308?

I am looking for an accuracy load for .308. I have both a SA NM M1A and a Savage 10FLP bolt gun.

Would some of you be willing to share your information?

Well, 41-42 gr imr4895, 168, mil case is a standard that normally does well. For 600 yards, my std load is 42.5 gr imr4064 with a sierra 175 in front.

At the moment, until I'm forced to change my brass brand again:

Worked over LC brass, Winchester WLR primer, fill with Varget and cap with a 175 Sierra Match King at 2.820" OAL.

Thanks for the info. Can any of you give me some information for Varget loads using the Sierra 168 grain HPBT? I am using Federal Match brass.

Jeff, two things.

1. If you're only shooting within 500, then staying with the 168 SMK is fine. If you're going beyond 500, go with the 175 SMK. Trust me. If you're saying "I'll shoot 90% at 500 and in, only 10% between 500 and 1K", then it really doesn't cost anything extra to just go with the 175 for everything. It's difficult to appreciate how much difference there is in the ballistics of the two, until you've done it. I've got a K of 168 SMKs that have been on my bench for years, ever since I tried the 175s. They're that good.

2. Federal match brass isn't exactly the best out there. It's S-O-F-T. If you want it to last beyond three loadings, you'll want to back off on it considerably. I've got a friend that doesn't have time to load for his custom match boltguns, so he purchases Fed GMM2 by the case. I essentially get the once-fired brass for free, if I want it. I don't use free Fed match, I purchase better, and then match prep it myself.

On the Varget advice, my statements would be very much different for a boltgun versus a self-loader (especially an M14!). Which one you loading for?

Bravo, I will only be shooting within 500 yards. I am not that good of a shot right now, but I am getting better. I will be loading for my Savage 10FLP. I shoot yhe Port and Aussie surplus in my M1A. Right now I am using the Federal brass because I got a lot of it pretty cheap. I think if I wanted to get real serious I would go with Norma or Lupua brass, or something along that line. I will get some better match brass when I have used up what I have. I don't think I will get many firings through my M1A. It is pretty brutal on the cases.

I have heard a lot of good about the 175 grain HPBT. I think I will try that bullet. Thanks for the info.

Jeff, not much I can help you with as far as loads go at this point, 'cause you've got your head in the right place.

Maybe dies? If you're looking for top accuracy, I can help you there. Downside: good dies aren't cheap.

As far as the fed brass goes, it doesn't matter if you use it in the '14 type or just your Savage, either way the primer pockets will go dead FAST. When you can thumb-seat 'em, that's too many times LOL!

If you're loading specifically for the Savage, and not running that ammo through the '14, the primer pockets MAY let you get away with 4 loadings, although I kind of doubt it.

I don't run Lapua in my '25. Too expensive. Instead, I buy decent brass, and then invest my time as far as labor goes......

My best load so far:
41.0 Grains of VihtaVuori N135 (burns clean and very consistent)
168 SMK seated to 2.82
CCI 200
LC case from the 'bad-crummy' XM80

Through my Oehler 35p I get:
High velocity-2630
Low Velocity-2617
Extreme Spread-13
Standard Deviation-5 (yes 5!!!)
Through my loaded standard M1A I consitently get 1 MOA at 100 throughout the year...when it real hot out here in the Tennessee summer the high velocity of this load only climbs to 2650 and only drops to 2612 at 20 degrees. HTH

Howdy Hey You,

I used N135 as well. Great powder. As you noted, very good on temperature stability. Tremendous on the clean-burning. Not so good on price (GRIN).

I rate it tied with H4895 (not IMR!) for second place in temperature stability. Not by a whole lot (as you noted), but some.

Varget gave me velocity changes that were within my ES, from hot-hot to too cold. As in, without a 10 round string to get an average, the velocities weren't distinguishable from hot to cold.

My SD was 8 fps, for a 10 round string.... the more rounds in the string, to a point, the higher the SD. Better sampling.

If it wasn't for that slight edge on temperature stability, I'd go with N135 too. I think I've still got a couple of kilos left in the stockpile.......

Commercial cases, usually FC but the same load works in RWS, Lapua and Norma and Hirtenberger brass. I don't mind much that the FC brass is soft, once fired FC is cheap and if I get three M14 loads out of it I'm happy. Nosler or Sierra 168g match bullets, 44.4g Varget and FC210M primers. In the M1A I can seat to an OAL of 2.825". The Sako AII Tactical has a shorter magazine so I've been seating to 2.805". I need to retest this load in LC brass.

Bravo, I have noticed hat the primer pockets of the Federal brass get softer after firings. It took no effort at all to seat the primers after just one firing. I didn't think anything about it until I read your thread.

Jeff, don't look at the bad side, think of it as an upside!

First off, you'll have significantly less time to invest in depriming. Heck, in another couple of firings, the primers will fall out on their own.

Second off, priming will be a lot easier, you won't need a machine to do it. Just dab some red loctite on the primer, and gently set it in the primer pocket.

But use a LOT of red loctite (GRIN).

And yes, that's my attempt at humor!

Bravo, I think that is funny. I remember having a hard time getting primers seated in Swiss 7.5 brass and this is quite a change.

I thought I would show a pic of my two ".308s". I think it is going to be fun loading for both of them. My wife bought me the M1A for my 50th birthday and the Savage for Christmas last year.
