Here's an article from The Truth About Guns that I had bookmarked: https://www.thetruthaboutguns.com/shotg ... best-uses/. It talks about the Mossberg OPSol mini-clip adapter (less than $20) that Carl mentioned, but notes that without the OPSol the author, Travis Pike, says that without it Mossbergs and Remingtons generally have cycling reliability issues. And I own exactly two brands of shotguns...Remington and Mossberg. Which is one reason I didn't pursue trying mini-shells. The OPSol only works in the Mossberg 500 series, including the Maverick 88.
Travis talks about the mini-shells with birdshot, buckshot, and slugs. He finds the slugs most intriguing, but of the buckshot he says:
YouTuber "mixup98" posted a year ago about using the mini-shells in a Remington 870. At the time I was considering the minis, my go-to was an 870 Tactical, so I found this review interesting (he also notes that his Mossberg with the OPSol adapter ran fine, and shows an explanation of why an adapter is available for the Mossberg series only; it's their construction of the lifter):That all being said, I wouldn’t use these shells for home defense. I believe the true purpose of a shotgun is be as devastating as possible with each pull of the trigger. Sure, we have to strike a balance between recoil and power, but I’d much rather use eight pellets of double aught versus these mini shells. If I needed capacity and lower recoil, a rifle would be my choice.
