    I need some recommendations for a replacement powder for my 243 ackley. Bartlien 1/8 barrel. I was using R23 but loaded my last grain this morning. Using 105 Berger hybrid bullets.

    It’s been a while since I did any research on this caliber but I would like to be between 3100-3200 fps without pushing the limits.

    Thanks for your help.

    This is a rabbit hole but I was able to bring up some technical data. Start here: https://www.6mmbr.com/243Win.html

    Read everything. At the bottom are links to guys who put these together in the past I just email my questions. They appreciated someone was ready to learn.

    Here’s one from the first page.

    Thanks. I have worn out the load data from 6mm br. I have a printed copy in my bench and it shows the signs of dirty fingers going through the pages.

    Seems like I will try some h4831sc. I also have some Imr 4831. I think I have some Retumbo and magnum in my stash
