It happens elsewhere as well.
I have had errors of spelling, fact etc, as well as awkward expression introduced into each of the manuscripts I've submitted to a local publication. Hunters and shooters in Aust generally bemoan the lack of consistent quality in the limited Australian hunting and shooting press. There's good stuff there, but a lot of dross.

I personally love DGJ, and it is miles ahead of anything we have in Aust.
