Hornady 208gr. Amax in a .308 for long range?

I found this post on another forum:

Quote:
308 Win
Win brass
208 AMax, moly'd
CCI 200
3.00 OAL
51 gr RL-17
2650 fps.

I intended to go long and check some drops so I bolted on the 16X Super Sniper. Shot two groups to get a 100 yard zero. First was four shots into .65", second was three shots into .65" again.

I then went out to a 1 moa wide white rock at 1320 yards. Dialed 46 moa per Quicktarget. Wind seemed very low and almost 6 oclock so I didn't dial any wind. First round was 1 mil left. I held one mil right, and the second and third shots were hits.
The general consensus in their discussion is that the 208gr AMax bullet has better terminal ballistics and bucks wind drift better than lighter bullets. Does anyone have any experience with these bullets in a .308? 2650 sounds awfully fast for a 208gr bullet from a .308.

RL-17 is reported to do very well in the heavier weight bullets. Check out the threads on practicalriflery. I think member oliveralan is messing around with that combination here.

Doesn't your Savage have a 1:10" twist? If so, you might be a good candidate for messing around with it.

Will the 3" OAL be a problem?

Don't have an answer to that one. I use 175 SMKs loaded to mag length (2.800").

Yeah, that's what I'm starting with because it's tried and true, and i need something ready to go by the 25th. After that, I may experiment a little.

I have a couple of boxes of the 208gr AMAXs sitting here to play with. This is initial load data from Hornady for this bullet:

208 AMX Initial Load Data:

308 Win- 208 Amax, WLR primer, Hornady brass, Win M70 22", 2.80", 1:12" twist

Varget-
Start load: 34.9 @ 2100 fps
Max load: 40.0 @ 2300 fps

IMR 4064
Start load: 36.2 @ 2100 fps
Max load: 41.0 @ 2350 fps

R15
Start load: 38.2 @ 2100 fps
Max load: 43.2 @ 2400 fps

Win 748
Start load: 37.9 @ 2100 fps
Max load: 44.6 @ 2450 fps


One thing to keep in mind is that there is a special seating insert for this round, at least for use in Hornday dies. I am planning on seeing about loading some up using the Varget load info but somehow I think it may be a bitch to get it down to 2.800" COL - almost certain to be a compressed load I'm thinking.

I use this load exclusively in my .308, was one of the first along with some guys on snipershide to play with it. Heck I built my f-t/r rig around this. I am shooting 48gr RL17 touching the lands (around 3.1" oal for me) 5 shots 1/3 moa at 100 under .5moa at 400. From a 300yard zero I dialed 26.5moa to 1000. Also chronoed my velocity and it corresponds with my drop. Just around 2800fps. I have a 28" 1-11tw hart. Dot believe me? Well I plan on being at quantico April 25th. Kicks pretty hard though.

2800 fps?? Holy monkey. Do you know what kind of chamber pressures you're getting? Have you tried these loads in a shorter barrel? Who's brass?

I might be taking a serious look at this bullet; I'm running a 1:10 24" barrel. I'm off to Bass Pro to see if they have any...

Would love to figure out how to get this to cycle in my .308 DPMS, which limits me to magazine length rounds. Anyone built anything to get to 2.800" COL?
