I have the mossy 715T flat top that I finally got around to shooting today. After 100 rounds I just put the snake down the barrel with the solvent and wire brush, nothing to complicated. So my questions are once the snake exited the barrel and went into the chamber it would hit the front of the bolt where the firing pin comes out. I don't think it was that hard but am I endanger of damaging anything? Also should I run some lubricant in the barrel as well?
