6.5 and 30 carbine are already pretty hard to come by unless you are alright with buying cheap tula ammo for a collectable rifle.
06 prices have remained pretty steady but high but there is absolutely no chance of supply ever running out.
54R is the cheapest and is everywhere b ut it won't stay that way forever. I would start stock it up before it breaks $100 per spam can.
8 mause is starting to get rare as is 303 brit, it's a bit of a trade off, 303 is more plentiful but there seems to be a lot more enfield shooters than mauser shooters(at least in my area anyway)
