Hope someone can help me here. Recently picked up a Taurus 1911 used. Gun has ran flawless. Did some shooting with my son and Dad today and noticed these damaged cases. I have 3 magazines. 1 Taurus 1 Novaks and 1 Kimber ( that does not seat well ). Next time out I will see if it is just from 1 mag, but in the meantime is there anything else I can look at?
Note there is a lot of discoloration on the damaged side?
Edit to add
This is all facrtory loads mixed brands.
This is also my 1st 1911
