Was out testing some handloads in my 5.7 FN yesterday. Got two failures to fire. Primers showed very light primer strikes. Factory 40 gr. ammo worked as it has for about 300 rds. now, which is as usual. Loads were not still .2 grs. below top end and the brass and primers were otherwise fine.
Fired cases showed the case's shouder moved forward a good bit over factory brass..... Too much headspace ?
The gun hasn't been cleaned for the last couple of years. So I cleaned it up and played with everything. Seemed to work as it should, but... only time will tell.
I'm not happy with this. The gun is suppose to work even when dirty. The handloads used factory ammo with their bullets pulled and my charges of powder and the Sierra 40 gr. Hornet bullet. All the other handloads have worked fine, BTW. But, yesterday, I got two in a row that wouldn't fire. After that, six rounds of factory ammo fired normally.
