Hi Curtis and welcome. No reliably in this are most Semi-Auto Shotguns. You would need more generated back pressure to properly cycle most semi-autos and these shorties are loaded with much less powder and payload weight. This is stated on the box of most mini shells as a disclaimer. Cheers and stay safe!

no the shorty shells dont generate enough pressure to operate the gas semi auto system

No, the lower pressure generated from the mini shells is not enough to cycle a semi-auto shotgun.
