I was loading some of my M855 loads (25gr. H335, non-loaded SS109 projectiles) this weekend. I loaded 50 of them, but while loading, I began to seal the primers using nail polish (blue, like some of the cool Federal M193). I put a small smear of it around the primer wall (? terminology?) in the primer hole, then seated the primer, wiped the excess off, then put it aside. The sealant was not slopped on, nor does any of it touch anywhere near the flashhole. I did 50, then thought, well I can take a rag soaked with mineral spirits, put some nail polish on it, then wipe the non-sealed, primed case to seal it, ensuring a more consistent and cleaner seal. It works! I did about 350 more rounds like that before calling it a night.
But my question regards the 50 loaded by the previous method: Will putting sealer on the sides of the primer cup cause it to back out upon firing? Would it potentially make it too slick to hold on, and cause it to back out? Priming pressure was about equal with a unsealed as a sealed. I would like to hope that these are to be used with the same confidence as the others.
BTW: The second method works great. I called a friend of mine who does that and got his recipe for that after I told him what I was doing. He put a few rounds in water for a week, took it out and all 30 fired (he actually put a whole AR mag filled into the water ).
