just from a visual sense, they look a little long to me. But the plunk test is the true test. If they all won't "plunk" correctly, then it's most likely a OAL issue.
I use a chamber checker to make sure my 9mm will chamber, but this won't check the OAL. Only the plunk test will do that.
As an aside, I always chamber check (Lyman) all of my 9mm's because I end up with range pickup quite often. Some will not pass and will have to be bulge busted back with the 9mm Mak FCD. The 9mm FCD will not fix it because of the taper.
After running them through it, they all fire and function correctly.
