Hey,
I know you're only asking for Venator's contact info and not a reference per se. However, I gotta speak up.
I bought a bunch of Venator "match" ammo from a friend who was hard up for money. I pulled the bullets and they looked (and weighed) like match bullets, so I bought them.
That 223 ammo was too hot to shoot in my NM AR-15!!!!! I've never heard of 223 ammo that was too hot in an AR-15. I ended up throwing that ammo away after several range attempts.
I hope you're looking for something other than 223.
