7wsm brass out of 300wsm?

[zr600]

Ok so I got some adg 300wsm brass. Now I know this will be a fireforming process. If i neck these down, check for excessive neck thickness, possibly turn neck if so, load into lands would this be a ok practice for good 7wsm brass?

use a false shoulder for best results. you need to move the shoulder around .040. your necks will end up short but people have done this in the past.
