Not wanting to pop anybody's balloon but forming 22-250 brass using .308 is about a 30 second job for each piece maybe less time once you get the hang of it. All you need is one 22-250 FL sizing die preferably an RCBS, one case trimmer maybe a LEE power trimmer, possibly a Wilson inside case reamer, and Imperial sizing die wax. Only apply Imperial on case body and case neck not on .308 neck so as not to wrinkle where the old neck was and the new 22-250 neck.

No need to anneal newly formed brass. Doing 100 cases should not wear you out if it does do the case forming in 2 days.

Fireform the new cases with heavier bullets like 55 grn jammed into barrel twice both times using a powder that will safely let you fill the case to mid neck level, like 4895 does. Do this when you have a couple days that will let concentrate on doing a good job.
