powder- 303 BR-Woodleigh bullets-215gr

[remie]

I purhased some Woodleigh bullets 215gr RNSN. I don't know what powder to use..I am currently using WIN 748 for my Hornady 150gr SP..Can someone please recommend a powder and starting load...thanks

A slower powder. H414, win 760, 4350 would all be about right.

The 4350's have always done well for me with heavy bullets in .303br..
H4350 may go a wee bit faster, and is not very temp. sensitive.
IMR4350 is often more accurate.

Data is out there, but PM me if you want info from my older manuals.

 

[Why not?]

I have loaded a lot of 215 gr bullets in the 303 Br over the years, and found IMR4320 to give very good velocity with good accuracy and case life.
