How easy is it to resize from 300saum to 7saum. Thinking of 7saum build and know at this point i would need to reload. Looking to do this with the least amount of steps and least complicated. If not I'll go 7wsm.
looks like all you need to do is run it through a 7saum resize die and trim the neck. I'd probably do an anneal after. If you anneal first be careful not to over anneal. I did that and collapsed some shoulders taking .308 down to .260 Rem
