I'm currently working on accuracy loads for my DPMS AR in .308. I have tried several powder/bullet combinations, but have not found the optimal load for my rifle - and this is the problem with making statements of accuracy - EVERY RIFLE IS DIFFERENT...with that said, I am hesitant to give reloading data out that is available online from any of the powder manufacturers websites. Typo's can cause serious problems, so whatever is said on a forum must be followed-up by personal research to verify the accuracy of any suggested loads. I will suggest that you buy Sierra Matchking bullets in either 150 gr. BTHP configuration or their equally accurate 168 gr. Matchking BTHP. The Sierra 168gr. Matchking is the preferred bullet/weight for accuracy/sniper applications. I have been using Hodgdon powders with very good results - I have loaded fairly accurate ammo with their H414, H4895, and H322 powders. I have achieved sub 1" groups at 100 yds. but will not be happy until I can cut that in half. To that end I am trying to obtain some BL-C(2) powder, which according to their catalog has produced top accuracy in the .308 for many years and in many competitions. I also read in the Hodgdon Manual that this is the powder that was originally developed for the 7.62 NATO cartridge (.308). I have been unable to locate this powder locally and will have to order it online. That being said, the Sierra 50th Anniversay Edition Rifle Reloading Manual states that top accuracy from their test barrel was achieved using 41.4 gr. of IMR 4064 on top of the Sierra Matchking 168gr. BTHP bullet. Velocity for this load is 2500 FPS. You can get load data onlline for the .308 at Hodgdon's website which is:Just getting some things added up for my reloading. Does anyone have some good specs for powder and bullets for a good target shooting .308 round, that they feeling like sharing? Looking for mainly accuracy here.
I've only had this happen with one caliber, and that was the 30-30, and only because I had reloaded those cases almost a dozen times before tossing them. Otherwise I have never experienced any problems with Rem. brass. Annealing is fine as long as you don't overdo it - that will cause split necks also.Remington brass has a "reputation" for being softer that most others. With repeated shooting and reloading the necks will become work hardened and potentially split. Consider anealing the necks every other loading to extend the life of the brass.
Whats the rate of twist of your barrel? I've noticed for some strange reason my 1 in 10" barrel seems to like bullet weights in the 150gr. range over the 168 match weight bullets. Maybe I just haven't found the right powder.I am having good luck with the 155gr Sierra Palma match kings. I have also tried 168gr SMK and 168gr Hornady match and A-Max bullets. Still working on shrinking group size for mine as I want no more than 1/4" at 100 yards out of my rifle. Once I find that load I am going to enter in an F-class match or two that are hear local. I am currently using Remington cases in my loads as a buddy of mine gave me 200 of them I also have 50 winchester cases both seam to work well.
+1 to 1-HOLE's comment. Stick with one bullet type, one brass type, and one primer type until you determine which powder works best for you.
Mine I think is a 1in 12 twist. Not to sure I have only measured with a cleaning rod and a very tight jag and patch. The barrel has nothing on it not even a caliber it is just a big old chunk of stainless steel.RL357Mag said:Whats the rate of twist of your barrel?

I looked into Lapua brass very quickly...at $34/50 I decided I was never going to be a sniper!Mine I think is a 1in 12 twist.

I plan on stepping it up to Laupa brass as they are the most consistent out there. They cost though boy do they cost. I might even switch to Berger bullets as well too not sure though.
I've used 3031 for my 30-30's and have achieved bolt action accuracy. I never tried it in the .308 however. Now I will have to. I began using spherical powder years ago because of the consistent throw from my powder measure.#1
Started loading the .308 about 45 years ago. Started with IMR 3031 and am still using it exclusively in the .308. A good bullet to start with is the 150 grain. Have not found any big difference between Federal, Winchester and Remington brass.
