I am very glad to see a section on combo guns and drillings.
How about a drilling thread to match the combo gun one?
I'll get it started with my "go-to gun" my old GDR Merkel in 16/16/7x65r. I've used in for the past 5-6 years in the US and in Europe and its never let me down on axis deer, red stag, mouflon, woodcock, partridges and pheasants.
