The "high brass" could either be Imperial "Special Long Range" or Imperial Magnum. I couldn't tell you if there is a difference in the height of the brass in the two. My old Dad only ever used Imperial Special Long Range in his old Tobin double for "Prairie Chicken" or "bush partridge". The did kick like a mule. I loved the smell of the empty hulls.... mmmmmm!![]()
If I recall correctly the "Special Long Range" shells have a standard brass colored primer while the "Magnum" (2-3/4") have a nickle plated primer. Same height of brass on both loads, I believe.
