Ive got maybe 150 total with headstamps including 300 BLK, 300 Whisper, 300 ACC Blackout as well as some converted LC, but I acquired them already converted so no idea how many times they might have been fired after conversion. I can sort them out and count by headstamp if you are interested.

I have some quantity of about 150 different calibers if there is something else you are looking for.

I'd be interested in 44 special and perhaps 30-30 as well as 44 mag - all once fired would be fine.
