3006, what is the normal twist rate used in the 10,75?

The more I look at this cartridge, the more I think it would be a practical and fun one to work with, except we don't have too many bullets for it.

Bullet diameter in COW is listed as .424, which means many jacketed .44 bullets are available that could easily be sized down to fit the bore, and some very practical loads could be developed for deer using such bullets. Also, of velocities were kept to 2000 fps or so, good work could be done with sized-down "heavy .44 Magnum" cast bullets, too.

Over here, .424 bullets are pretty scarce otherwise.

Those who know both cartridges; Do .404 groove depths run .421 as per COW, or are they commonly deeper as are some other early 20th Century Mauser cartridges? What do common .404 bullets measure?

Seems like even .421 ".404" bullets could be used in the 10.75 as I shoot .366 bullets in my .369 groove depth M146 Husqvarna with good accuracy, and many others do so with Husky's possessing .370 groove barrels.

At the velocities you are suggesting, 3006, I think a sleek 21 Brno wouldn't have to weigh more than 7 or 7 1/2 lbs and still be shootable. Seems like the dog handlers might like such a carbine, too.

Just some further musings...
