This stuff is simply amazing. Even though I hold the national record with the M1903, I still worry about the “frequent” binding up of the bolt while trying to feed a round into the chamber. This one particular rifle I compete with is bone-stock, definitely NOT match conditioned, so it has a tendency to make for some very interesting rapid-fire strings. I put some of this [Eagle Tears] oil on my bolt and receiver rails just before a match and actually snickered a bit during my rapid-fire string—it was unbelievable how smooth it made the action.
