Accurate #7 seems to get some good results.

Load any 147gr and it will be subsonic.

Yep!

Caution with the powders although suitable ones will all work, the faster burn rates will stress the brass a lot more in 147 grain loads.

I have used Win 231, Accurate #2, #5, and #7. Suppressed use I would not use #2 or probably 231. For suppressed/sub sonic target loads use I use 124 grain FMJ and lead cast or 147 grain lead cast and most often grab AA #5 or #7 to reduce brass fatigue.

I've been using 3.7 of unique with berrys 147s 1.13 OAL. If I was running a can it might be alittle dirty for that, but I haven't had any problems with it at all
