Hi everyone. This is a copy of a post I placed on another site with almost no response. True it is about a shotgun but I could really use some input from others who have had a similar problem and found a fix.

I could really use your help here. I won't go into the history of how I came to be the owner of a Beretta Pintail but I have one and I am satisfied with it except for the fact that it cycles sluggishly when I have less than 100 rounds through it. In freezing or near freezing weather this sluggish behavior becomes noticeable after 20 rounds and by 30 rounds the bolt stops its forward motion as the shell lifter is in its lift cycle.
I tried running the gun completely dry of lube and I also stretched the recoil spring two inches longer than its relaxed length when removed from the gun.
It seems that the powder residue is what is gumming up the bearing surfaces between the bolt body (mostly on top of the bolt) and the inside of the receiver.
What should I do? I can try another ammo (I heard that Federal makes a clean burning steel shot load). Should I use MORE lube than in warm weather and if so which one? Grease or oil and why? Is it an option to have either the inside of the receiver or the outside of the bolt body hard chromed?
Help!
