Treblig clearly doesnt have much experience with modern steel and the right chokes. Destry said it right and I agree. We shoot Ducks and Geese in Nebraska 30-40 days per year and dont lose many birds. I am fussing, as we speak, with a 30" Marlin 90, to make it shoot steel well. I had Scott Carlson put a choke tube in the full bbl, so I can shoot Mod+whatever is needed for whatever I am shooting that day. Like Destry I shoot older guns, and flat cant afford the cost of Nice Shot etc. in the volume I shoot. I did buy some 10 bore RSTs non tox, and it does well in my Lefever "E".
