Re: Questions about my savage .308
My experience with 10FP .308's is that they tend to have shorter throats then many other factory rifles. This could result in rounds chambering well into the rifling, and perhaps spiking pressures somewhat. Working with NATO fodder, which IMHO tends to be rather hotloaded, I could see where a case might get stuck once in awhile.
First thing I'd suggest would be to see if you can find a cartridge that causes the bolt to close hard, then shortening the cartridge (very) slightly, a very little at a time, with a common vise, and seeing if this has any effect on bolt closure effort. If so, then your rounds are probably seated a tad long for the Savage chamber/throat combination.
Although this situation can be an issue with some ammo, the main compensating offset is that the shorter throat takes a lot more rounds to erode to the point where accuracy fades.
Summing up, I've seen this before with several Savage 10FP .308's, especially with newguy handloads, and I consider this to actually be sorta normal for this model.
Considering the potential advantage on throat life, it's a condition I find somewhat easier to live with, and take into consideration when handloading. It may come to a point where it may make sense to get a handloader buddy to shorten up the OAL a little on your NATO ammo, just bumping the seating depth a little deeper.
Simplest solution I can think of.
