If you’re referring to HaYen’s post, of course component availability has something to do with most for the least. It’s hard to get the most out of something when you can’t even find frigging components. In fact, getting the most for the least would also apply to component prices, not just cartridge efficiency. For instance, Lake City 308 or 223 brass can be bought cheap; more bang for your buck compared to a round that only has Lapua brass availability. Funny thing is I’ve never seen an actual difference in the hunting field between guns shooting the two. Maybe a bit more accurate on paper with the Lapua, but not enough difference to matter in real life (i.e. hunting/varmints).
