George, They funtioned perfect. Accuracy was good. I was getting 3-4" groups @ 15ft, The goldensaber's were tighter about 2-3" groups.
I only shot 10 mags full od blazer's, But there were no problems.
I have never really used them either, but I got a case of them (1000 rds) for $50.00 a while back and have no complaints.
The quality is good although accuracy is not as tight as other target ammo I use.
I recently shot for comparision some brown box military 115g and winchester white box ball in my glock 26, The blazer was giving me 4-5" groups while the other stuff was consistantly 2-3" @ 20ft.
