I have run about 200 rds of mostly bulk ammo thru this gun while trying to find time to work up a handload. Some no name bulk, some LC bulk and some new Aguila,all 155 gr, all with terrible accuracy results but all chambered just fine
Found some Federal 7.62 168 gr match and some military LC 173 gr match. The Federal would not chamber and when pulling the stuck bolt back the bullet pulled out and spilled powder everywhere. Cleaned it up and tried another round, same results.
Tried the LC military and most of it will not chamber. The bullet did stay in place so no spilled powder.
Any ideas why the match grade ammo tends to not chamber?
I finally worked up a few handloads using MK 168 bullets and accuracy was much improved at 100 yds.
