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.

Thank you guys for all of the feedback.
Thanks to one of our generous members I am good to go. Quail season is open until February.
I am hoping to squeeze in as much quail
Hunting as possible between now and then.

Phil, Just in case you run out of bismuth, you can shoot steel through open choked barrels with no damage. If you have less than .020" constriction there is enough compression in the steel loads to pass through the choke without stressing the barrels. That said,the bismuth or tungsten matrix loads are much more efficient and hard hitting. I have shot steel through and older VH choked .005" and .015" with no problem.That is also very close to the chokes on the repro steel shot specials.

Thank you John for this information.

Modern steel shot loads are WAY superior to the steel offerings of 30 years ago. That said, stay away from the "cheap" steel loads (Promotional 'field' loads at $12-14 a box) and spring for the premium steel loads. For example, Remington Nitro-Steel, Kent Fasteel,etc. Should be $30-50 a box. For small ducks, shot size 4-5; for large ducks 2-4.

I'd shoot steel all day in an RBL.

Also, look at Boss Ammo. Boss uses copper-plated Bismuth, and the stuff works great! They load everything from .410 to 12ga in all sorts of configurations. I've used Boss for ducks in 12ga and 16ga, and they pattern wonderfully. I believe Boss has dove/quail-type loads with 71/2 shot size.
