I have an 1867 danish rolling block. I thought it was chambered in 45-70 but to get a lee 459-500-3r to touch the rifling it’s barely up to the first grease groove. Could it be a 45-90 or just have a really long throat? It doesn’t give great accuracy with them seated to normal 45-70 oal. Could I load it long like that to just plink with it or is that too much air space in the case?
