Beretta A300 Outlander

Is there a spring adjustment on it? Not enough gas in the low brass to work the action. I have a weatherby shotgun that has a ring to put in the spring cylinder for low power shells like that.

I would suggest a deep cleaning for any auto that starts having feeding trouble.

That gun should reliably cycle those shells if it is clean and in good working order.

Need to get down to the piston, cylinder, mag tube, and action to clean them well. Then lightly oil per the manufacturers recommendations.

Lots of videos online.

Hope this helps.

I’ll add the chamber to this as well. I have a B-80 that’s a beretta 302 clone that struggled with dove loads but not target loads of the same weight/loading. Cleaned the gas system and action but it still wouldn’t cycle. The target loads were smooth but dove loads were a textured plastic and I noticed a little tighter to pull out by hand. Looked down the barrel and saw some crud in the chamber, tiny bit of plastic or dirt maybe. Turns out the cheaper dove loads fit the slightest bit tighter in the chamber, were getting hung up against the crud, extractor would slip, and it would jam. Hit it with a brass brush and then lightly oiled inside, and it fixed the issue completely.
