Question on 9MM loads
I have reloaded Mixed Brass in 9MM with 3.8 grains of titegroup with cci primers and a hornady 124 grain flat point with OAL of 1.050. These are going 1105 measured on a chrony.
When shot out of a taurus 92AF I get a bulge in the primer that looks like it moves the primer back into the bolt face expanding it slightly back into the firing pin champher.
With this light of a load I do not think it is an overpressure sign.
I am going to shoot some factory ammo through it tomorrow to see what they do.
Any thoughtson what might be the cause?
