Can't say best for your particular application, but let me be the first of a long list that will recommend H335, WW748, TAC, etc... H335 is very hard to beat (I use mag primers with it), and I have some great 55 grain loads using AA 2460. I prefer the ball propellants mentioned for ease of use, great metering, and an uncompressed load density of about 95-98%.
Good luck.
