I compared the Barnes data for all their listed powders with those same powders for 'regular' 185's in three other manuals, looked at velocities, maxes, and powder weights.
I think gunner500 had it right.
I intend to start at 6.5 gr. of Unique and step up until I reach 1000 fps. or a max of 7.0, with accuracy.
Half a grain should be worth a little more than 50 fps., so 6.5 might have me there already.

(What could possibly go wrong? grin )
