A VERY light coat of oil is all that's needed on your bolt and it's parts, especially in cold weather, below 40 degree's. Nothing wrong with a little silicone or very light oil but excess oil or heavy oiling (or any grease) in cold weather is a bad combination for bolts and other moving parts. It can also attract dust and dirt and hold it where you don't want it to reside.

The Remington dry lubricant or any graphite or molybdenum-disulfide products are great for cold weather.

Hope you get your bolt/pin sliding smooth again.
