Lefever shells for 20Ga. Low Pressure?

[DuggerWebster]

So I have a 20Ga Lefever that I have never shot.. looks and feels tight and I know it's a 2.5" shell length.. Any good advise on shells to put through it for
1: skeet and 2:dove 3: Fall pheasants?

Thank you for your time

You should also have a competent double gun smith give it a once over to be sure it’s safe to shoot.

What grade is it? Assume it's a Durstan Special, which is the most common Lefever seen in 20 ga. They , of course,, have fluid steel barrels. As an alternative to RSTs, you could reload low pressure 20 ga shells with 3/4 oz. Very mild recoil, and effective on grouse, quail, etc.
I've had two DS Lefevers, and that's what I shot thru them.
Low pressure 7/8 oz are nice also.
