the best advice i can give here is to measure the internal volumn and compare it to known cases.
remington has about 4 different case volumns out at any given time.
in fact federal and win do the same thing.
i found this out the hard way [like most everything else]
but measure the internal volumn so you know where you are starting. then do the work-up like in metallic loading.
it's worth the hassle, if the hulls are any good.
