I've been loading mine with 225 Partitions for years, but am hoping to switch to 200 AB's to save a couple bucks. those PT's are a buck a piece! I just ordered 150 of those 200 AB's for <$0.50/ea from Shooters Pro Shop
Great powders: IMR4895, IMR 4320 and my personal favorite: TAC. Supposed to use mag primers with TAC to get better ignition.
I have no experience with the Barnes bullets in the 358. If I were to try them, I'd sure lead with the 200 TTSX. Velocities will never be really high in a 358 due to case capacity. Still a pleasure to shoot. I carry a takedown BLR and love that rifle.
