208 Amax's or 210 bergers in 308

[Freeze]

Hey, I have gone through the 308 load thread and haven't really found much there. Wondering if anyone has had decent luck with either the 208's or 210's out of a 308. I have a 1-10 twist rock creek at 22 inches and currently run 175 bergers out of it. Not even really sure if its worth it, but thinking about giving it a whirl. Would be with lapua brass, and 210m primers. Don't have consistent access to vit, powders but everything else is readily available.

Stay tuned, I've got some Hornady 208's and 210's comming from Berger, Sierra and JLK. I'm going to run a comparison like I did with the 155's.

I have a Broughton 1-10 at 22 inches.

I'm currently using:
208 Amax
Fed brass
Rem Lg rifle primers
W760 47.5 gr
1.95 OAL

I'm getting over 2500fps consistantly. Good spreads just need to play with it to get the accuracy. I'm going to go up by .1 to 47.9 to dial it in. I'm trying to get consistant .5 inch groups.

Cool guys thanks for the the input. What would be a decent powder other then the viht powders?

Freeze,

You might get good results with RL 17, since it is similar to VV N-550. I soft seat moly 210 JLKs to 3.25" in my 26" Remington and use 47gr. of the 550 with WLR primers. The throat on that rifle is very long, so work up to see how much powder and bullet fits in your case. I tried the Hornady 208s, but they wouldn't fit in the case. The bullet seems to be above the trans-sonic speed to 1k, velocity is around 2600f/s. Drops like a rock, though.

HTH,
DocB

R15 is used in several of the 208/210 grain 308 loads. R17 might a good one to play with also. These heavy bullets would be a great bullet for 800-1000+ yards.

I use the 208 AMAX with RL15. The AMAXes are a bit cheaper, at least for now compared to the Bergers. Just as good BC.

Well I did up so loads andhere are the pics. It was a nice 1 degree celsius out and I was at 4450 ft above sea. There was really no wind until the end when the nice breeze from a storm that was coming hit me and slmost froze my hands off. I really didn't know where to start my loads at as I have never used this powder and there wasn't a lot of info. Started at 41.5 and worked up in 1.2 grain increments. Usually I would not go up like that, but being as I really don't know the window for loading this round I figured I would shoot them, see how they grouped and where I started to see pressure signs and work back from there. So I went from 41.5-44. For the first while I just thought I was having a bad day, but at the very end I fired my normal load of 175 bergers over 45.8g of varget. All were shot at 100m prone off a bipod with a bean bag at the rear. ALl 5 shot groups.
1st

2nd

3rd

4th

5th

6th-like this load. Pulled the forth shot and was really pissed. Knew exactly what I did when I did it and was pissed cause I saw how the first three were grouping. Without the screwup by me the 4 rounds messured .266

Normal load 10 round group. 175 Bergers, 45.8g varget. First 5 were in that nice little mass. Then the cold wind started and well, I rushed and blew it out a little.

All in all it was a good trip. Cold weather made eht barrel cool quick. Had no signs of pressure at 44 grains so I am gonna keep moving up till I do and then back down and try and find a good load. Also need to borrow my buddies chrono so I know how fast these buggers are flying, but I like them so far. Oh and rifle is a Nesika KT action, 21.75 inch rock creek m40 barrel, AICS 2.0, with a NSX 5.5-22x56. Stay tuned. I will show more when I got it.
1 more pic of the entire target setup so every knows there wasn't and flying flyers.

I had a similar result at 44.0 gr. with respect to the flyer in the group. Its possible that the load isn't quite on the accuracy node at 44.0. Try bumping it up another 0.3-0.5 gr.

Re: 208 Amax's or 210 bergers in 308

Yeah I am gonna keep going up till I see some preassure and then I will work up by .2 gr when am a close to there to tune it in. Or it was just me shooting bad. Gonna try another load at 44.0 its worth a look.
