I was trying to be as parsimonius as possible, to avoid wasting peoples' time with irrelevant details (and potentially irrelevant replies with advice I don't yet need or want), but since you asked...
Based on the measurements provided by
@bowhunter123456789, my 175 ELDX @ 0.02" off the lands is almost identical to the Precision hunter, though substantially shorter than I expected from a cartridge designed to keep the bullet out of the powder volume, as well as compared to another 7PRC barrel I had (returned as defective for other reasons, and replaced with this one).
What really has me concerned, is that the180 ELDM and 190 A-tip are ~0.20" and ~0.07" shorter to the lands than the 3.32" OAL quoted in the Hornady Manual. This is particularly weird, since my 7mm Mag, as well as the other 7PRC barrel had the ATIP and ELDM at very similar OAL/BTO to the ELDX.
Something seems wrong, but I like to get my ducks in a line before confronting a manufactuer. Since I only reload, and have no factory ammo to compare, I was hoping the fine folks here at LRH could help me determine if the throat is so short as to not even allow for factory ammo. In my book, that would put me squarely into a "warranty" issue, as apposed to "I wish it was longer" issue.
So...Anyone have some data on some 180 ELDM factory ammo, so I can check that off my list?
