I have had poor results with H-110 with bullets heaver tan 135 grs in 300 blk. (blown primers as pressure builds very rapid with this powder)
Look at the loading data and make a list of the usable powders, for when you go shopping.

I don't have powder yet. This is my first reloading ever. I have h110 on back order.

This, IME. IMR 4227 is easy to find, and cycles my gas system in supers no problem. Haven't had much time to play with subs, but I'm not going to bother with load development with them until my stamp comes in anyways - I've read that 4227 is doable with a subs, a can, and an adjustable pistol-length gas system, but I'll wait and try it for myself.
Anyways, I save the H110 for the 110 and 125 grain bullets, and use 4227 for 147 pulls and 150's. To be honest, I'd start off reloading a different (read:easier) cartridge with a lot more published data, and move to 300 blk after getting some experience under your belt, but that's just me. The same basics apply, so it's certainly possible to start with 300 blk - don't let me get you down. I've just had to experiment with this cartridge a hell of a lot more than other cartridges.
