And are there good steel options for factory 20ga?
When using steel shot in a 20 gauge on pheasants, I think it’s best to go with 20-gauge 3-inch 1-ounce loads of either #3 or #2 steel. Steel shot lethality research conducted on pheasants by Tom Roster showed #2 steel to be more effective (at all ranges) than either #6 or #4 steel. Yes, you can kill them with #4 or #6 steel loads, but a little extra pellet energy is a good thing on wild pheasants where shots tend to be at going-away angles and can get on the long side. The research also showed #2 steel resulted in fewer cripples than both #6 and #4 steel; and Roster also speculated that the #3 steel pellet would be a good compromise between pellet count and downrange energy.
Here are a few of my pattern numbers to give you an idea of how these loads perform, in my gun/chokes!
Pattern numbers from a 20-gauge Browning Citori with 28" Invector-plus barrels and Briley flush chokes (patterns average of five, 30" post-shot inscribed circle, yardage taped muzzle to target, and in-shell pellet count average of five).
