Need a powder

[filric48]

I'm loading 303 British 185gr cast need several types of powder to chose from I'm going to Bass Pro and there selection is sparse, the manuals I have don't have 185gr just 200gr. I also need how many grs. to put in the case.

I don't load 303 but you could google "Ed Harris, the load" for one option loading cast.

I have had good luck with it on loading cast with 8x56r.

Cast bullets are usually loaded to lower pressure levels. Take a look on some of the cast bullets sites.

I use 16gr. of 2400 under a cast 173gr gas check lead bullet in my Mk 1 #3 .303 Enfield. Its the "200 yard load" Harris writes about. Accurate in my rifle.
