I'm loading .308 for two of my sons for their Sig 716s. One uses Peterson, the other is using Starline. The Starline is loaded for 150 Hornady SST and the Peterson is loaded for 168 SMK. So far for the 150 SST we've tried Varget, N140, N150, N540 and it like N540 the best, so far. Not too deep into it yet, but dialing it in.Anyone loading Lake City brass in .308? Opinions and information request for 150 grain Partitions. MTG
I've been loading it for over 45 years. We used to get Lake City Match brass, brand new from the Department of Civilian Marksmanship for $10 per 100 in the 1980's.Anyone loading Lake City brass in .308? Opinions and information request for 150 grain Partitions. MTG
I am going to disagree with this a little. LC. FC and Lapua are all very similar in case capacity and published loads based on those cases don't very that much. HOWEVER, loads based on some of the lighter cases such as Winchester, Hornady, and some Black Hills will vary significantly and the 2gn suggestion does come into play.I've been loading it for over 45 years.

Most published starting loads are at, or very near, maximum when using Lake City 7.62x51mm brass. A good rule of thumb is to use 2.0 full grains less powder than whatever you have been using in commercial .308 cases.
The same here, I have some LC 308 Match brass that shot lots better than the run of the mill military brass but when I tried some Peterson Palma type with the small primer/small flash hole that was definitely a step up…I have a few hundred '93-'94 LC Match cases I obtained in that time frame that had been fired initially in military 7.62 sniper rifles. I sat on those cases for 30 years until I scoped my old M1A last year. They are heavier than the Federal and Winchester cases I used back then but the weights are very consistent. I have had to reduce powder charges 2-3 grains to get to my target velocity and I am getting decent accuracy. Nothing earth shaking but decent. Also, the brass is rather hard and sizing takes noticeably more pressure. I had to toss commercial brass after 3-4 loadings back in the day. This brass is tough enough I'd say I may be able to double the number of loadings. We'll see.
