I found this on ammo-guide (though i let me subscription lapse after i found lots of the diagrams were off in angles and some measurements.
its more-so written and intended as a DGR not a LR caliber

Good evening all, Looking for some advise after receiving these in the post a week ago...
I seem to be the luckiest man on the planet having my NEW 7mm Dakota brass neck turned out of the factory... apparently.
I have been palmed off to the Australia importer by the retailer outlet i bought...
Would be interesting to see how long the throat is. Mine is extremely long to the point I swapped out the bolt release for a 270 30/06 and run a long mag. COAL is 3.08” with Berger 140VLD’s
Pet load is 44gn ADI 2209 (H4350/IMR4350)
I have tested with success 45.2gn but have found my T3 in 260...
In my experience, though the weight consistency is nice and reassuring some-what it does not have ANY relevance to shooting what so ever... OCD yes but if you H2O sort yours brass you will find that they will all be within 0.1-0.2 grains of each other.
5000FPS was reached before but it wasn’t done with the massive boiler rooms discussed in the first few pages.
it might have been stated before in pages 3-8 of this thread. I think 22 earsplaterboomer was only estimated to but the 224 Macdonald (case design close to a 22 dasher)
34in barrel...
