20" Bartlein 1:10 .299/.308 - getting an average of 2882 fps. with 155 Scenars and IMR 8208 XBR.
Factory tactical R700 20" gets the 155's going ~2740 with varget.
19.5 " Kreiger (close enough?).... I get 2800-2850 with 155 Scenars
and 2950-2970 with some 130's that a buddy made for me years ago.
YMMV
wes in AZ
still in need of a Rem 700 SA RH .473 face Bolt....long story.....

46gr Varget in Lapua brass with 155 scenar ran 2800 in my 20" Remmy 5R. I got well over that with load development but they didn't shoot as good as that charge and it worked in several rifles. Depending on exact bullet, powder charge, and barrel you should be looking at 2750-2900FPS. Never loaded any 130's but I do have some 110Vmax data in 308's if you want that.
In a 1:11 or slower twist they shoot great, I couldn't get them or the 110gr Sierra to shoot well in my AAC-SD 1:10 or GAP with 1:10. In the two 1:12 rifles and the 1:11.25 rifle I had no problem finding a load that they shot as well as any other. I thought I loaded the, for my 20" 5r but I didn't. I do have data for them with my 24" 5R, 20" LTR, and 24" AI AE with a 4 groove 1:12 Lothar. I don't have charge numbers writin down on the LTR and it's been long enough that I don't remember but my dope shows 3160FPS. I know that it was with Varget. The 24" 5R was 3210FPS with 51gr Varget in Hornady brass and the AIAE with 3290 with 50.5gr in Lapua brass.
They will make a groundhog unrecognizable if you hit it right as far as 300 yards out. Beyond that the velocity really drops off and once you get beyond 500 yards the accuracy really drops off and hits on varmint sized game are next to impossible. The bullet is still supersonic but it just isn't accurate. Even on paper on calm days it was inconsistent beyond 500 in all 3 rifles.
I had a 300RUM built with a 31" 1:15 twist 3 groove pacnor specifically for the light bullets. I ended up with a 110 VMAX at just over 4200FPS with more left in it. It only dropped 1.8mils to 600 yards from a 100 yard zero. When I was coyote hunting or killing deer on damage stamps I ran my elevation to a 300 yard zero and could hold dead on beyond 400 yards. It was stupid on a coyote, they would be all but torn in half and the small damage stamp deer of central VA didn't fair any better. I'm curious how they would work at 308 velocities on deer, I've used 87gr VMAX in 243 and it works well.

Good to know, if I wanted a tad more reach w/light recoil and in a varmint bullet I would try the 125 Ballistic tip if a 10 twist is too fast for a 110. 110gr of lead, or 125 in a deer's chest is not going to make him happy 
I dropped them with 70gr TNTs in a 6BR at 200 yds broadside, and from a 243 at 45 yds. 3400 and 3500mv respective.
Thanks for the info.

I had some Sierra 125gr. spitzers, and loaded them on a whim. They shot great, at 100. 1/2-3/4 in. groups.46.6 grns-h4895 at 2.700 COL, out of a stock 5R.
