Re: 308 Load Help
I agree with Bounty, have pretty well switched to the 175's for shooting past 700. We shoot a steel target at 1100 and found that the 175's need less wind and seem to shoot better. Have never found any sideways looking splats on the steel with either bullet (expect that might mean keyholing).
Let's face it, the .308 is an 800 yard cartridge, accuracy starts to go rather quickly after that distance.
Like Wyo, we use Varget and have not found anything better. 44.0 - 46.0 grains is usually where the accuracy is. We load to an O.L. of 2.830" since we want the rounds to feed thru Win. and Rem. actions. Have had very good luck with Winchester brass and standard Winchester primers in our rifles. 4064 is the Federal match ammo powder loaded but Varget will usually do as well. There is also a powder called Benchmark from Hodgdon that is supposed to be excellent but we stick with Varget.
Don't forget the 155's, in Nosler, Lapua, Sierra and that slick A-Max from Hornady. I haven't used them but all the target-weenie shooters use them exclusively.
You are on the right track using the .308 Win. as your entry cartridge into long range shooting and hunting. You would be surprised how many guys buy a big honking magnum so as to get into LR shooting and then find that the game is way more difficult than they thought. Learning the skills (wind reading is the big one) is much easier with a moderate recoiling rifle than a bruiser.
If you need any info re drops, wind etc. we got 'em. Good luck.
