IMR4064 getting no love but seems to give me best accuracy, velocity respectable, and best of all seems to be readily available. Plus loved the old blue cans!

H4350 and Varget which you already have are among the best. Also very temp stable unlike many of the powders others are listing

Agree with the H4350 for the heavier pills. H4831 is good too. Varget is better for slightly lighter weights. In my experience, most Reloader series powders are dirty. Staball gave me great accuracy and decent speed, but terrible ES/SD.
You ve gotten good advice here. I would add that if you re shooting heavy 6mm bullets then any thing from 4350 burn rate AND slower will perform well. The ole 243 is more overbore than a lot of folks realize thus it will take a shine to 7828, H1000, R26 and even Retumbo in long barrels. Retumbo ends up slightly compressed should you try any of that.
Good luck

Yeah same here. .223Rem, 270Win and 308Win. Tried it in my 6mm Creedmoor that showed pressure signs under 87gr VMAX. Decided to try this with 75 gr VMAX.

H1000 with magnum primers. 4350 as well.
Of powder I've seen readily available the IMR4451 and StaBall 6.5 will work nicely. Being you have H4350 already and if you have a good supply just run with it.
