I am looking for some info on what people are having the best luck with in their 6.8 SPC spec II's. Best powder and bullet mainly. I did a search it and comes back with nothing. So I skimmed the first 90 pages of the reloading forum and only found about 3 posts about 6.8 load info. Nastynatefish has one of the best so far. Please don't post a link to 68forum's I have been on there reading everything I can find for the last three days. There are alot of good opinions over there but honestly if I can't get a 6.8 to shoot any better then most of those guys I probably won't keep it long... Lay it on me!

MPFD, I've have good luck with the AA2200 with most bullets I tried. That being said I have only tried the 115 sierra ph, 100 hornady sp and I just got some of the 90 sierra's. I had tried some exterminator but got better groups with the 2200. I just got the 90's and loaded 5 up with 30 gr and a col of 2.90 and shot a 5 shot group under a inch. The gun i shoot is one of Scott's uppers. I settled in with 28 gr with the Hornady 100's and a col of 2.90. I can't remember on the 115's I'll check when I get home.

RL-10x for 110 gr. VMax, and 90 gr. Sierra HP loads. I tried
RL-10x for some Barnes 95 gr. TTSX loads, but the velocity
was lower than I expected. I have some RL-7 loads done and
waiting for some time on the range. Also the disappointing
velocities were in a RRA 6.8 SPC upper. I have a new 6.8 SPC
upper built, with an AR Performance barrel(6.8 ARP chamber and
hybrid 5R rifling 11.25 twist), sitting on a Armalite NM lower.
I am hoping to get to 2800 fps with the 95 gr. Barnes.

I am not sure why you have an issue with 6.8forums, but they
have the best load data there is for the 6.8 SPC.

I'm just not impressed. To many threads about shooting bullets I would never use. Seems if I find something impressive I get to the bottom of their reply to find they are shooting groups @ 50 yards, or they admit their guns shoots 3 moa at a hundred, but they are working up loads with an eotech. I pride myself on making a rifle shoot small groups @ 100, not shooting man sized targets at 50 and killing zombies...

Ok I'll take some of that back I have found some decent threads on there today. Which loads are good for both? Will the Saami loads work in the spec II or is it vice versa?

I use Exterminator and reloader 10X for the 110gr sierra pro hunter and the 95gr Barnes TTSX. You should be able to hit 2800 with the 95 gr barnes without too much trouble. As to your question, you can use saami loads in your spec II but not the other way around.

Mine is a 16" 10 twist and these are its favorite:

90 TNT 28.5 viht n133

110 sierra pro hunter 27.8 benchmark

115 Nosler hpbt 25.5 viht n133

100 Hornady sp 27.8 AA2230

out of the extensive and exhausting testing, these loads show extreme promise. I know a couple other guys who tried the 90 tnt load and the 115 hpbt and they also shot very good in their rifles.

H-322 give me the best groups but not the most vel.
My 6.8 has a Pacnor barrel and a jewell trigger and will shoot most loads under 1" the best loads into one hole @ 100yrds.
H-322 R10 and 2230 are only powders I run.

Wilson Combat Stainless 16" 6.8 SPC II barrel
This is my hunting rifle
Optic- Leupold 2-7x33mm duplex crosshair

120gr Hornady SST's - Deer / Hog Load
loaded to 2.295" OAL
H4198 24gr = 2470fps - 2500fps
Win Large Primers
Rem Brass
Groups 1/2" at 100yds

Loaded in Hornady brass
CCI 41 primer
H4198 24gr
Gave the same Point of Impact which was intersting
Under 1/2" - a little tighter group
Didn't chrono it for velocity

H4198 gave a lot of gas pressure so I use a heavy spring with a standard buffer and bolt function / lockup / consistency is solid.
A standard buffer spring was too light in function for the amount of gas pressure I encountered.



YMMV
