They shoot great, Train like you will “use it.” So I went to the range and ran a couple of boxes to really see if they had enough “powder” to cycle smoothly in what I use and never had any malfunctions. I have been through 4 boxes now and never had one that was defective in any way. G.H. really pays attention to details. Run a sale and I will definitely stock up 😁!!! I have them in all my things, EDC, home unit. etc etc...
