I recall that round, when o bummer got elected you couldn’t find any of that ammo anywhere.
Ashley had a friend with a gun in that round back then and I recall him hitting me up. I’d say if you get one have the coin to buy several cases and stock up. I personally don’t need another round and I like the .22mag in the pmr-30 obviously not comparable ballistics but I have several rifles and pistols in 22wmr already and it’s a light fairly powerful round. That pistol has 30 rd mags too.
I’ve personally been stocking up on .410 as of late. When looking at my inventory I was light on small game shot. The wife and I are planning on grouse hunting this year to get us out of the cabin after the big game push is over.
I don't necessarily see myself as needing a 5.7 but a few of the operators were all over that gun over in the stan. Not sure if anyone got shot by one over there, have to ask around.
And the .410 thing is a great idea. You had me wanting to buy two. One for me and one for an up and coming grand daughter who needs to do some field time with me.
