I often circle around this subject myself and always talk myself out of a new rifle... I know, there is no such thing as too many rifles but the toy budget is rather limited these days after retirement so I have to be selective of what I buy.
I really wanted a .22 Hornet and have almost bought one several times but then I think I'd be better off with a .223, , 7.62x39 or .308 all of which are readily available and brass will be with us for a long time to come. .22 Hornet brass is not common here. .223 brass and .308 brass is everywhere and lots of range pick up available and 7.62x 39 is not far behind. Any of those three or a wildcat based off one of those cartridges ensures a guy can reload as long as powder and primers are available... and of course lead to cast boolots. They can be downloaded with .223 being a good substitute for .22 Hornet or RF.
So far I am using my Lee Enfield .303's loaded with Mihec 316410 130 gr. bullets as my lightweight plinker. Not quite as efficient as the smaller cartridges and mor elead thna a .22 regardless but still much less expensive than full loads with regular weight bullets. One of the other three may be in my future!
There are different ways of skinning that cat!
