I have a Kimber Classic Select in .308 that I bought in December, 2006. During load development in 2007 I had no misfires and was very pleased with the accuracy of the rifle. I probably shot it about 100-125 times during this phase.
Opening day of our 2007 deer season I had a misfire but lifted the bolt handle to re-cock and tried again on same cartridge and killed the deer. A few days later I had this same thing happen again. This made two misfires in six rounds. (Temps were in the upper 40s or low 50s when the misfires occurred.)
I returned the rifle to my dealer and provided them some of my handloads as well. They opined that my loads were at fault. But they also said there was a fair amount of grease in the bolt and that there is some sort of adjustment to increase firing pin spring tension which they increased and cleaned the grease out of the bolt. They test fired the rifle and returned it to me and I've shot it a couple of times since without problem. (Since I got the rifle back it seems to my ear that the firing pin is falling harder.)
It is certainly possible that, as they said, my primers were not fully seated in the cases and that caused the problems. However, I have loaded several thousand rounds of ammo and have never had such a problem before so it strikes me as odd that it happened twice within six rounds without some sort of rifle issue being involved in the problem.
I really like the rifle and I plan to shoot it a good bit after deer season ends to try to determine if the problem is corrected.
I have a friend who bought a Montana model Kimber from the same dealer and he also had problem with his rifle misfiring on factory ammo. That rifle was eventually returned to Kimber and was corrected when it returned. However, as I recall, my friend was soured on the rifle by the experience and got rid of it.
I also have a Kimber varmint rifle in .204. I've shot this rifle 700 plus rounds (with my handloads) with never a misfire problem.
Bottom line, based on my limited experience, I think I've encountered the problem you mentioned but you probably shouldn't extrapolate a general rule from my limited experience.
