I would like to duplicate the Winchester 243 Supreme load that uses the 95gr combined technologys bullet. Anyone have any ideas?
winchester claimes 3100 fps. I wonder if they are useing Win 760 powder? Anyone have any experience with the Win Supreme load?

Have you dumped one out to see what type of powder it is (stick, ball)?

I havn't bought any. Just been reading about it. It's getting very good reviews.

760 or H 414...

I've disassembled several...easily duplicated.. even if it is another flake powder, you can duplicate the MV with H 414...

and probably exceed it with RL 19 or RL 17...

accuracy will be less with RL 17... but right there with RL 19....

IMR 7828SSC will also exceed that... and give you about 3250 fps MV along with stellar accuracy...

Thanks!
