Shotgun jamming

[Versatile Hunter]

My semiauto Beretta a300 jammed hard last week while duck hunting. Looks like the powder residue + remnant oil froze in the unusually cold weather. I’ve taken the gun apart, cleaned it thoroughly with Shooter’s Choice Quick Scrub, and very lightly oiled with Break Free CLP. The action now feels smooth. 

I didn’t remove the recoil pad to open up the tube housing the recoil spring to ensure it isn’t rusted. It looks like it’d be a PITA and I may need some extra tools to do it. Is there any rule of thumb for how much force should be required to pull back the action for proper shell cycling? I can’t quite tell if the action is a little stiffer due to spring rusting or if this if this is how it’s always been.

Is this the first time your gun jammed? Gas guns usually have stiffer actions than inertia guns to begin with

Are there numbers I can use as reference? I can’t find them. 

I’ve had minor issues with the gun occasionally jamming on light rounds while shooting clays. But the cold duck hunt was ridiculous. Slide wouldn’t move. By all accounts this was frozen grit in the action.

May have just been a little too dirty or had little/too much oil in the action. Light trap loads can be hard for semi's to handle sometimes. Not sure what numbers you're asking for though
