303 British load

[Vovchyk]

Hi folks,
I have half a can of Winchester 748 powder I feel ashamed to throw out, and some cast 303 bullets and brass. Any chance I can combine these?

Just messing with my Quickload, it will work but I have never personally seen it used .
I have some older books I will check as well .

758 is right between 4320( faster) and Blc2 ( slower)
And although I didn’t find anything in the first two manuals I checked for 748, both had data for 4320

What bullet weight?Al Miller in The Art of Bullet Casting said it Win 748 was the most accurate powder in his tests.Will print data for the weight or do you want it all?Everything from 168gr - 198gr

old Winchester load data lists the following fir jacketed bullets
150 PSP=45.4 of 748
180 SP = 39.8 of 748
These would be max loads of course
