Why pay a bunch (since cost is a concern) for a .222 or other relic when a .223 can be loaded down just as easily? I like the old ones myself, but finding and feeding them can be problematic.
That 46gr Speer FP shoots very well in my 1-16” Hornet, but so do 40gr VMaxes.
There was an article on the .218 in Handloader 342, Feb. of this year. A 43 was used to develop the loads IIRC.
