Hoyt, WSS had some Maxi brass, and I think I have another bag of 100
if I can find the second bag, it's yours, if you want it.
my local WSS still had more when I last looked.
when I dropped on in my Maggie, I still had 3-4mm left to go, and that was new brass, so assume a sized neck?
I'm not sure a SW would fit in mine.
I was going to trim a couple down until it fit, but haven't gotten to that yet.
I can even toss a couple in the mail for you to size down to find out., but I'd suggest they need to be expanded first, then size and a WC seated, just to be sure.
PM me on this if you want.
