150 gr cast in .303 Sav.

[gerry303ca]

I normally shoot 180 gr. cast in my .303 Sav. I'm all out of them, but have lots of 150 gr cast that I would like to shoot in it that didn't work well in my .303 Brit. The Enfield works best with bullets sized .312 or .313. My Savage works great with 180 gr sized .311. I can't find any data for .303 Savage anywhere. I generally use H 4227 or IMR 4198. Does anyone have load data I could try?

Data for the 30-30 Winchester will work for 303 Savage. Start low and work up. I have a second year Savage 99 that digests anything from 150 to180. I have actual 303 Savage data but the difference compared to 30-30 is minor. Only have 4 303 Savage cases so I had to make them out of 303 British. Took too long to order them in and I wanted to shoot. I may be slightly on the cheap side also.
