@Kevin Stenberg , if there's a 222 up for sale and you like the rifle - jump on it. You probably already know what a joy they are to shoot, and sort of a "natural" with cast to boot. If you bought that 340 in 222, I could stop kicking myself for passing one up a couple (three?) years ago for $250, and it looked well-cared for.
Lube dents be damned!
That's just me though, spiting the socio-economic/political situation which presumes to dictate to me that I can't shoot. But then, I'd wear a skirt and lipstick to work if the "wrong" person tried to dictate to me that I CAN'T. If you think about it, cast-bullet shooters are all kind of like that anyway, or we'd all just shoot jacketed bullets.
At least the 222 is one you CAN make brass for from one of the few cartridges dominating production resources right now. If I had to live with lube dents to shoot my 222, I would, just to spite the "situation." I don't know that ANY brass is "easy" to find right now. When you DO find brass, it's selling for more than what loaded cartridges did not that long before this last drought.
ONE of the MANY endearing traits of the 222 is that brass is much more an INVESTMENT than and EXPENSE for and expendable item.
I also THINK, but haven't tried yet, that new or maybe once-fired 223 brass might form OK. Ken Waters seemed to think "one pas through a 222 die" is all it takes. Just read that last night. I tried a few cases on tired, old LC cases and I got some dents in spite of being careful to keep the lube off the shoulder,..... but wait, the "SHOULDER" of the newly formed 222 case is in a different spot than the SHOULDER of the original 223 case! WHERE you DON'T put the lube is NOT on the SHOULDER of the 223 case. (?) There's an epiphany for ya! I just thought of that. Maybe lube dents are NOT mandatory.
Lube dents have always been a mark of shame to me, but my pride went out the window as primers went above $30/C and a lot of brass I like went to the back burner for production. I think we could figure it out, but I wouldn't let it stop me form having a 222 if I couldn't conclusively prove it before-hand.
