There are lots of powders that will safely do 2800 with a 140 grain bullet so you will just have
to experiment. I use H414 and it exceeds 2800 ft/sec. For hunting my pet load is A 120 grain
ballistic tip, RP cases, CCI BR4 primers and 49.5 grains of h 414 for 3010 in cold weather.In warm
weather it speeds up to over 3100 ft/sec so be careful in hot weather.
I found that the 120 grain actually out performs the 140s on game and the extra velocity
makes it a lot flatter.
I and others have made shots well beyond 500 yards that were one shot kills "DRT".
