I don’t know of any published/tested short 10 loads using the new IMR Alliant clones other than the ones on the Hodgdon site & none of them looked good to me. Charges really large in volume. Speed and pressure look fine just use a lot more powder. Having said that Alliant Blue dot loads use big charges too.
Burn rate is important. I recommend sticking with PGCA member tested Alliant 19 Red Dot or 23.5 Green Dot loads.
