We have black purebred Murray Greys, the result of 11 years of careful breeding. These are purebred Murray Greys, with Murray Grey conformation and characteristics - not "throwbacks" to Angus. The Angus/Milking Shorthorn cross was done 100+ years ago, for heaven's sake.
As for feed conversion, I won't try and give you stats, but my personal experience with Murray Greys is they are exceptionally calm and easy to handle, which translates to excellent feed conversion and growth.
I'm not breed bashing, either, and didn't take your post as such, Frankie.
