Alliant ReLoder 17, Anybody Use This In the 303 British Or 7.65 X 53 ??

I called Alliant and Hornady asking about RL17 in the 303 British and was told that they have not developed loads for a cartridge that is not very popular.
I bought about #6 of it awhile back and developed loads in my Encore 243 Win pistol that shot very well. Seems to be close to 4350 in it so thought it might work well in some of my other guns. I did load up some 30-06 loads today with the 150gr Partition as there is load data for it.

Has anyone developed loads for RL17 in cartridges like the 303 British, 7.65 X 53 Arg, 30-40 Krag, etc???If so can you post your results?

RL17 is close to the 4350 family with some extra oomph. I think Hodgdon has data for those cartridges you listed in 4350. Haven't used it in any of those cartridges. But so far I like what it can do in the 06 family cases and belted magnums. It is a pretty newish? powder, so only the latest editions of books I have found to have data. QickLoad update included RL17 as well
