Hey,
I recently bought a Fierce arms rifle in 300 PRC. When I took it to the range for the first time, I immediately noticed that the bolt lift gets heavier after furring and that there are 2 protrusions on the case where the ejector pins sit (see picture). My first thought was that the ammo might be too hot but seemed somewhat unlikely since it is Hornady factory ammo out of two different lots. I did not have the opportunity to measure with a chronograph. In a different thread here I red that it might be due to tolerances, soft brass or oil in the chamber. It just seems strange to me that it would cause protrusions rather than indentations. I have 2 more ammo boxes on the way from 2 different manufacturers to see if it's the same or not. If it matters, the diameters almost match perfectly and the protrusion is about 0.0030 although it's kind of hard to measure. Anyone have any other ideas?
