I bought a can of this after reading Taffin or someone? who experienced excellent accuracy with VV n-110 under a heavy ssk 340 cast bullet in his 45. I have an 45 LBT 325 WFN that drops ww bullet wieghing 342 grains gas checked and lubed, so I thought I'd try it. Taffin used 17.0 grains.
I tried it today and the results were all over the place on the target and over the chrono. Velocity for 50 rounds ranged from a low of 832 to a high of 1032 with an average of around 945. Groups were 3.5 inches or worse from 25 yards. Maybe the SSK sits alot deeper in the case.
I will try 17.5 and 18.0 next I guess. Thing is that this powder only comes in a 2 LB keg too, so I hope it works out for me.
