Sorry to get into this thread so late...
Buffalo Arms offers .318 bullets in 200 and 176 gr. I'm using the 200gr in my drilling and working up to a hunting load. I managed to get some RWS ammo and it clocked at 2500fps. I also have S&B, but have not chronographed it yet.
The RWS shot 6" above POA at 50yds, and I've been told the iron sight is indexed at 150m and it hits about 1-2" high at that distance (still have to do some more 100yd range time.)
My load so far is 39.5gr IMR4064, but will try 41, 42, 43 grains of same. 42 grains is the starting load for the .323 size 8x57JS in the Speer manual.
