9.3x64 I get 1800fps out of the 63.0gr AR2209 load in my 404 which has a long throat. I use one wool wad over the powder and a CCI250 Magnum primer. I have shot this load without the wad but sometimes I got a very very slight ignition delay, or so it seemed to me, but with a wad I always get good ignition, again maybe the long throat has some effect.

Like VG I did not use a wad with the red dot load (VG sent me enough red dot for 10 or 12 rounds.
I have developed my own plinker load using 22.5grs Unique with the 350 gr cast bullet and no wad. i use Win LR primers with these plinkers.

Two targets below are 50m 3 shot groups on a good day using my 2x Leupold scope in an EER position on the Mauser. The bottom target is the 63.0gr AR2209 loading.
