I have had a friend run QL - the SAAMI on the .303 British using a 215gr Woodleigh which was specifically designed for .303 British velocities as a comparison tool for load work. Then I used a velocity calculator to estimate reduced charges that are under any book load max charges to use for staring points with the following powders and the 215gr Woodleigh RN.

Thought about it and I want the 215gr for the close work I will do with my 303.


.303 British Loads for 215gr Woodleigh RN
(Note: I recommend the near max loads must be reduced by 5grs to start with in any .303 Enfield and start with the reduced loads found listed after the near max loads)
