Opinion worth what it cost here's another.

OP did not mention Phesants at first. Game should be shot with adequate loads. Around here Phesant shooting would be low volume and that Smith may handle couple of boxes a year OK. I would pattern it, tight chokes don't need as much shot to produce killing patterns. You may find 7/8 is all it needs.

High volume modern 1 oz load I would not trust it not to crack.
