I used that load data when I started. Also look at the 208 AMAX thread. Lots of loads in there.

Hill Billy, were you using the VLD's or the HPBT version. Also were you loading them long, touching lands ie, got a bunch or different 210's and really looking for a good starting point.

If you're not going to use RL-17, don't bother with the expensive and heavy 210s.
Stick with the 155s and Varget, as you won't get the 208s/210s up to any meaniful velocity to offset the gains in the high BC 155s at ~2950 fps velocities.

I think just the HPBT. I loaded them to 3.00. Not quite touching the lands in my factory Tikka.

Chris, 155's and varget don't work for everyone, not in my stick anyways, but its a great combo. Everyone knows lot of folks are having great success with RL17 & the 208 Amax. Theres a big trend towards heavier bullets in 308 especially in F class competition but more towards the 185 and 200 grain pills. I leaned more towards the heavier weight because of what Litz had to say, I think theres still some good heavier bullet/powder combos out there if you are willing to sacrifice speed, of course this is just my opinion.

I just got 3 boxes of 208gr AMAX from Wheres-Waldo (from here) and I got 2# of RL-17 from Bass Pro Shops (got raped at $28/#) so I'm going to play with this combo, but you really can't get any meaningful velocities with any other powders that we traditionally use, when using those +200 gr bullets. Hence, my comments. You just have to run the numbers and see for yourself.
I shoot the 185gr Lapua bullets, so I have an idea.

Re: Load data for 210 SMK in .308?
For fun, I tried them in a LR308 with not so good results, but there's a caveat in that something didn't go according to plan from load testing to shooting at range. My OCW test showed about a 55fps increase total from 45.6 to 47.1 grains of RL-17. The spread looked like this:
45.6 - 2,369; 2,341; 2,329
45.9 - 2,373; 2,342; 2,342
46.2 - 2,358; 2,341; 2,355
46.5 - 2,367; 2,351; 2,363
46.8 - 2,363; 2,379; 2,393
47.1 - 2,376; 2,411
No pressure signs at 47.1. These velocities were through a 20" barrel. The 46.8 charge was tight; didn't measure it but it was less than 3/8" for those three shots, easy. There was no doubt where the node was from what I could tell. I'll post a pic of my test target tomorrow, but in the end I chose 46.8 without further development, which wasn't smart except to say I only bought one box of the 210 SGKs, and didn't realize there were only 50 in there. I shot that load at 440 and 620 yards and my groups were measured in feet, but strangely my velocity averaged 2,437 fps, so something wasn't right.
For me, I think it begs another look when I have the time, but running the numbers through the Shooter ap for Droid shows my pooper 155 grain handloads @ 2,668fps average shoot flatter than these. Wind drift is another matter, which is why I chose to try them in the first place. BTW, the COAL for this load was like 2.180" to ogive to get them to feed in the C-Products magazines; they wouldn't feed in the DPMS mags. The higher pressure was my fear, and the reason why I stayed low on the charge weights. I hope this helps.

Thanks for the data. I'll bookmark this post, along with another tread on the heavies and RL-17.
Having fiddled with the numbers on my Palm, out on the patio, I think one needs to get the heavies up between 2600 and 2700 fps, to realize that gain in wind deflection, vis-a-vis the 155 Skinnies at upwards of 2950 fps.
From your data, you're not even close to 2500 fps, so as I said somewhere above, it's a 'waste' to go that route. 210/208s are more money and since they're heavier, they thump you a bit more with recoil.
For me, this is more an exercise as to whether I can duplicate the numbers others are realizing out of my Savage 10FP.
