.300-221 and .300 AAC case and OAL specs?

[grey2112]

As part of my New Year's resolution regarding reloading, I'm putting together a 3-ring binder with my reloading data, specs, illustrations, etc.

I'm having a hard time finding a case and round spec illustration or data on the .300-221 and the .300 AAC Blackout.

Could someone help me out?

I need all pertinent information on case length, shoulder width, all other widths along the case, and a good OAL range.

Thanks!

Brass should be 1.348 to 1.368.

Loading ammo longer than about (depending on the bullet shape) 2.150 tends to not feed well from a USGI mag with more than about 10 rounds in it.

Just note that those are either chamber or reamer drawings (at min or close to min) and not max brass drawings. Max brass size is smaller than either of those.
