45 ACP Blazer Brass report

[Byron]

My pistol is a Ruger P90.Prior to shooting the Blazer Brass 45 ACP. I shot Remington UMC 230 grain HP with no malfuntions.When shooting the Blazer Brass,the last round would not chamber all the way. I then shot a box of Atlanta Arms reloads with no malfuntions.The same magazine was used with all ammo. Byron

Weird. I've never had a problem with BB. Same with WWB. Atlanta Arms Ammo is a different story.
