Use data for 4895 which is faster burning and work up to the load you want.
I'd start around 30 gr and work up from there.
I use 4895 data. With that, I get some really good loads.
I use the next heaviest minimum, or start load data for each weight I do. I also paper patch them so I can push them spritely.
I definately understand your not wanting to fool around here. I like results also.
I just minimum start load data. If the neck is black, I drop some more in, if it is clean after firing, I stay there.
you did not say who's 4064.....i, a. ??
generic
29 gr around 20kpsi
40 ish is close to max too many variables to say where.
only accurate rifles are interesting
4064 either IMR or AA should be a good powder for the .303. It is one of my favorites for .308 and .35 Remington. Jonk's suggestion of 30 grains as a starting load should certainly be safe although each gun is a universe unto itself. If you have a chronograph then that will also tell you when to add more powder and when to stop. I think that you should be able to drive that boolit at or near the 2000 fps assuming a solid rifle.
I have a IMR 2007 reloading pamphlet with 150 and 180 grain loads. They are as follows. These are Max loads for Jacketed rounds. A 10% reduction for the 180 load may give you a safe Max for your 200 grain cast. 30 sounds like a good place to start.
150 = 44.7
180 = 41.1
