Several companies make a nice 150 gr. bullet you can load in the X39 Speer,Sierra .311 are the most common I also like the Priv Partizan .311 150 gr. SP when Graf has them in stocks,which has been awhile.
I get excellent results with all three bullets loaded to 2.200 inches,no compressed load problems using Reloader #7 and the data from the Lee manual. I've also loaded lots of Bulgarian Surplus 149 and 182 gr. FMJ's for plinking ammo. The old 182's put a pretty good thump on steel plates.
