Question on steel shot

[David Foote]

I shoot an RBL 20 for ducks. I use 3” bismouth. I think the RBL can handle anything you feed it.

It is important to recognize that 20g Bismuth and Tungsten waterfowl and turkey loads are boomers; those listed here are 3" 1 oz. or more and at > 1300 fps

Epic Ammo has a 2 3/4" load with 3/4 oz. Bismuth at 1350 fps

Apex Ammo Tungsten Upland is 3" at 1500 fps

As David said, probably not an issue with a RBL and No. 7s in a target load should be fine for quail with the right choke over dogs.
