jesse8953 Posted December 7, 2009 Report Share Posted December 7, 2009 My nephew has a 20 gauge autoloader that does not cycle the 2nd shell when it gets cold.We have taken it apart and cleaned it but without a blind heater in the duck boat it jams after the first shot.He was mad a few times this season and said he was sick of it and going to get a pump gun so he didn't have the problem any more.Is there a better oil to clean it with so it cycles through?We have used remoil and hoppies and the gun jams in the cold.

92xj Posted December 8, 2009 Report Share Posted December 8, 2009 Is the shell not ejecting out of the mag tube? Is the spent shell not ejecting out of the chamber / barrell? Is the slide coming all the way back and not springing back forward? How is it "jamming"? Quote Link to comment Share on other sites More sharing options...
jm23494 Posted December 8, 2009 Report Share Posted December 8, 2009 A few more questions: What kind of shotgun is it? Is it not loading a particular kind of shell or does it not function for everything? Are you putting a light coat of oil on it or heavy? How far do you break the gun down when you clean it?

jesse8953 Posted December 8, 2009 Author Report Share Posted December 8, 2009 The spent shell not ejecting out of the chamber.The gun is a tri-star 20 gauge.Had same problem with 3 inch remington turkey shells and 3 inch kent fast steel.Not sure on the thickness of the oil or how far the gun was broke down when cleaned.My brother cleaned it when I was not there.

Adjam5 Posted December 8, 2009 Report Share Posted December 8, 2009 I would imagine the loads are stout enough to cycle the bolt, but it might be a o ring on the piston in the gas chamber that is letting gas blow by without using that recoil/gas to eject the shell. I have never heard a TriStar shotgun, but most semi autos have a piston to cycle the gases and that piston has rings to stop the gas and push the bolt back, eject and load another. Check those rings and lube with Break Free CLP. It has teflon in it and it don't freeze. Good Luck. Quote Link to comment Share on other sites More sharing options...
TBow Posted December 19, 2009 Report Share Posted December 19, 2009 I have an autoloader that I've had for over 40 years. It has only failed to cycle a shell once in that span of time and it was a result of shooting poorly crimped reloads. I was always told (and have practiced it religeously) to use NO oil or lubricant whatsoever on the cylinder and gas rings that slide over it. I simply wipe the cylinder and rings down with a clean dry rag or kleenex. If there's a build-up to any degree, you may have to use steel wool to clear any excess build-up on the cylinder. Putting any kind of lubricant on it tends to pick up any of the dirt from the exhaust which will act as a restriction to the ring(s) sliding on the cylinder. Also any type of oil will change in viscosity due to temperature (thicker when cold) and cause a slower action. I know others may not agree with me, but I've got 40 years of success to back up the NO OIL/LUBRICANT claim. TBow Quote Link to comment Share on other sites More sharing options...
Shaun_300 Posted December 20, 2009 Report Share Posted December 20, 2009 Sounds like a seal issue to me, when it's cold the seal shrinks and lets the gas blow by like Anthony said, when it's warm it's expanded and seals, allowing it to cycle properly.
