I posted last year on this story but tell it again.
Had a nice 220lb dressed buck come within 8 yard away.
It was the coldest morning I had ever been out in with the gun. 0 degrees Farenhiet.
I had the bead on him already and click, cycled another round while this buck posed for another picture. CLICK!... Guess what the buck ran away and didn' t leave me a clear 3rd shot.
It was a Remington 870 pump using Remington 3 inch sluggers.
This thing shot out quarters at 50 yards with the Hastings rifled barrel
I cleaned the gun thoroughly and lightly oiled it in under instructions from one of the best gunsmiths in our area.
I told him I used that rust check to coat the barrel to keep the moisture from rusting it.
This must have dripped down into the firing pin in the bolt.
He told me that their is carnuba wax in that stuff and it will clog up the mechanism, especially when it' s cold.
Moral;
Don' t use rust check or let it drip into the action of your gun and then go hunt in freezing tempuratures.
GOD BLESS,
