Yeah not sure what that means.

Low but consistent?

Dropping lots but accurate you mean?

or just consistently bad?

Sorry, should've been more descriptive. Dropping lots, I think. Also I am not the best shot, so, could be me, but they do hit lower than factory rounds. Group was okay though (for me), will post more details when I get home.

More likely a different point of impact to your factory rounds. I wouldn't translate a lower point of impact to a weak load until you start pushing it out to further distances

Likely that the factory loads would be 100-150 fps faster than your starting load so a lower POI would make some sense.

I use the 168 grain Sierra projectiles in both my 308s and in my 300 winmag. 46 grains of 2208 flattens the primers pretty well but also sometimes jams my pump action due to cases getting stuck. I found that dropping back to 45 grains stops the jamming in the pumpy and still shoots out accurately at distance in my Sako. If you are trying to save a bit of cash then try 2206h. You can achieve similar muzzle velocities with a bit less powder so you might save a few bucks if you do heaps of shooting.
It's not banned in Queensland but you just can't have one!
