My experience with Lee minie balls is with my P53 Enfield (A Pedersoli). The boolits drop right around .576 (Pb) and the bore is probably right at .577, so they don't have to bump up any more than a few thousands to grab the rifling. And the accuracy is phenomenal. But with the Sniders, it's quite a stretch to expect them to expand up .025" - .030".
Over the winter (or whenever I get time) I plan to make up a sizer that will take the necks down just enough so they are back in round and see where I'm at on the case mouth ID. After all, if the fired cases are coming out with ID around .610 (+/- .005") a .605" boolit shouldn't be an issue...
