I didn't want to hi jack migrant hunters thread below. I am in the same boat. Went out had a 300 win mag built on a rem action, trued action, jury barrel, Bought Norma brass started fire forming brass as I was working up a load. However when I went to start resizing my brass I had to wait on my bushings, so I thought I would start by just nocking the primers out. Spent a few dollars on a good set of dies ( whidden die set). What I didn't check for was the expander ball, knock all the primers out and when I finally realized the expander ball was .338 in diameter which was stretching the brass. My question is should I throw out them brass or try and full length size them. If I full length size would I be working the necks to much. I did email whidden and they are sending proper size expander ball.
Rookie mistake

If it is 1-F brass, you should be able to size them back down to 30 cal without incident.
Norma brass is initially well-annealed, so I would not anticipate any grief.
However, you may want to anneal those cases before too many firings/resizings.
My thought is you should have been able to notice that .338 expander going through
those necks, even though they were expanded some from firing. [Rookie mistake, lol]

Not really. I often neck up 30-06 brass to 338 and the resistance is hardly noticeable, especially if the inside of the neck is well lubricated. .
My thoughts as well.
