I may be confusing myself on shot size vs ounce but maybe not. How many ounces of shot will I need to reload for pheasant? Is this dictated on the "charge bar"? I'm using a MEC loader. I'm reloading for a 20-gauge, #6 steel shot, 2 3/4" hull.
It sounds as if you are new to reloading. I think it best if you find someone to show you the ropes and/or read one of Lyman's reloading books.
As far as steel loads for pheasants go, #3 and #2 steel loads are what you should be looking for. And in a 20ga, 3" 1-ounce loads would be preferred!
Here is some info I put together on 20ga 3" steel factory loads to give you an idea of how they perform. I've shot a good number of pheasants with these loads.
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).
