(My shooting buddy bought a Remingtom .223 with 1:12 twist, and the gunshop sold him some 69gn ammo... they went through the target sideways at 25 yds!!)

Any medium speed RIFLE powder will do... Something like Ramshot TAC is what I use for 55gns, and Vhit N140 for 69gns... but check published loading data...

The shop has a 25m range, so me and a mate tried quite a few before I chose this. I know it's only 25m, but when I zerod it, all three shots went through the same hole, and the correct way around
