Maybe the vacuum created as the bullet travels down the barrel can pull it enough to get it started down the barrel? If so it would have to be aligned well enough to make it past the shoulder and into the barrel. Hopefully completely out of it as the next fired round would be a bummer.
Am I way off base here?
You are waaaaaaaaaaaaaaaaaaaaaaaaay off base!
There is no "Vacuum"... The loud noise you hear from the rifle going off is ~12,000 pounds per square inch of pressure being released... and your steel pin going out the barrel with it.
The steel pin can damage your bore. You need to get a cage tumbler to get the pins out when the cases are dry.
This is one of the issues that has stopped me from using SS pins to get brass clean. Final quality inspection is your priority. As you reload, stand the cases up in the loading block and inspect the cases with a flash light. Passing a magnet over the cases while they are standing up in the loading block might be a great idea prior to inspecting. If one of those pins goes down your barrel, it is not going to be a good thing, as the pin may be harder than the barrel or close to it.
I am sure that others with experience in this area will chime in.
