Join the club.... I posted the same inquiry last week. I don't think you can buy factory loads for this caliber anymore - it all just depends on who may have some extra boxes left over. Unless you're willing to pay ~$60 a box from Midway USA - I was not.
I think he would be fine shooting regular 222 Rem ammo.No major differnce between the two in my reloading books.Other than a .020 case length and it takes a little more powder when reloading.I also think it could be fire formed easily from regular ammo and reloaded.If he wants to invest in saving money.If my observation is incorrect please correct me.
