I tried to load some 180 gr interbond with varget and they shot horrible. Ran the from 42-44 grains of varget. Grouping was nearly 4".
Before you blame my shooting. Lol! I have been grouping around 1" with 165 gr SST.
just wondering if anyone else has experienced this.

Reran my ocw with 165 sst 42-44g varget here are my results.
I chose 43,5 as my node and then shot several with varying OAL.
I never got a group I was happy with.
I am thinking to try the node at 42.5 and see what happens or I may go to 180g interbond. Any thoughts?

Not trying to argue, just seems odd on my velocities and I am in process of loading a lower batch for ocw test now. I will let y'all know how next test goes. Hope y'all are right.
My velocity is around 2500 at 45 grains
I'm afraid I will be shooting really slow at 42g. Like I said earlier I didn't get to 2600 range until I get to 45-46 grains

Previous test
I never got pressure signs on any of the high charge rounds, top two charges ran about 2700 fps.
I ran the test earlier with charges from 42.5-45 grains but had .5 increments which was to wide.
We'll my velocities on the last two charges were around 2700.
I had no pressure signs when I worked up to that point and even during test.
I also had these test at lower charges from 42.5 through 45 but I did it at .5 increments I understand to be too far apart.
Here are those results.

Help! I just completed my OCW test on my 308 DPMS SASS AR-10.
I followed the procedure and shot round robin, calm day, 1 minute between shots.
Just not sure what to do? The POI's are just all over, but each groups remain consistent.
What do I do?
