Random comments.
-The 3.0-inch 28 Gauge, at 14,000psi is pretty high pressure for a shotgun tied with 3.5 inch 12 gauge for the highest within SAAMI.
-This cartridge pushes 1-1/8oz @1200fps that is super common in 12 gauge 2-3/4, that's nice but will it pattern as good from the smaller bore? Probably not. Going to kick like a mule in many of the lighter true 28 gauge frames.
The 21 Sharps seems interesting in that is has the shallowest rifling of any cartridge I can think of. The difference between groves and lands in only .005 giving us .0025 deep groves, where most cartridges are usually ~.004 deep. As speculated in other threads this might be due to it being supposedly slated for an all copper projectile and the shallow rifling would lower pressure as the bullet is driven into the rifling. Just a guess.

Agreed on the bolt thrust. The higher pressure means greater setback on the payload though and that means you more likely to get deformed shot unless you run buffers and or harder shot. Not a big deal. The higher pressure is also likely to be harder on hulls. As with most things there is a trade off. The higher pressure is going to give better performance but at a cost.

I am not familiar with 28 gauge shotguns.
How many 28 gauges are actually manufactured with a 3" chamber?
I would hate to see a rash of messed up shotguns from firing a lot of 3" shells in a 2 3/4" chamber.
As far as the 21 Sharps, I have no interest in it. Plus Winchester's track record with other calibers they introduced. Where are all the WSSM calibers now days. And if they load their 21 Sharps ammo like their 22LR ammo, don't expect much out of them.

Both look like they are expecting a prohibition on lead.

Company seeing “supply chain” getting back to normal and trying to liven up business with novelties?
Thinking Skeet shooters want to hunt with their sub-gauge?
My FLG has an interest in one ounce 28 ga which may already be a step too far.
Me?
My old Verney Carron 12 ga is a light weight and an ounce of shot is a gracious plenty.

I think one shotgun was initially made in 3” 28, I read about the Benelli a while ago. I think Beretta also is currently chambering in the 3” 28 ga, since they and Benelli are sister companies that makes sense.
I have two 28 ga, a Red Label O/U and a BPS. I don’t think either one would be fun shooting a 12ga equivalent load, a 3/4 oz #8 dove load is downright fun.
Stay safe.

I’m not sure how much a 3” 28 gets you over a 20 gauge. I don’t know they’re that much lighter to carry and 20s are well established.
I like the 20 gauge a lot. You can load 1 1/8 in a 2 3/4 20 hull. You just need the right wads and Federal hulls. Getting anything other than WAA20 equivalent wads is tricky these days. With a 3“ you can get 1 1/4 oz.
I agree this is an effort to make the 28 able to handle non-toxic (or differently toxic) shot.

Bought a box of 3" at Scheels and didn't realize they were 3"until I got home. No 3" gun. Did see a 3" gun go through the local gun shop. Aside from pressure deforming the shot, small bores with a large payload will make the shot string longer.
It's the American way, bigger is better. In the UK they load 7/8 oz in a 12 gauge. Maybe they are on to something.
