Why no 50 gr varmageddon in .22 cal?

[2ndtimer]

Just was wondering why no 50 gr Varmageddon for the .223? Did Nosler contract to sell all the 50 gr production to ATK for the Federal American Eagle AR 223 LCT ammo (Varmint Tipped?) I was just wondering since the Federal 50 gr Tipped AR 223 bullets sure look a lot like the 55 gr Varmageddon bullets I recently purchased, and was surprised that Nosler only offers the 40 and 55 gr versions. Any plans to expand the Varmageddon line to inclued 50 gr tipped bullets in .22 cal?
