No with 300 blackout, OAL is an issue as that portion of the mag is intended to ride on the case neck of 223/556 rounds. Depending on the bullet you want the circumference of the bullet at that point to be roughly the same diameter of a 223/556 case neck. If not you could end up with feed issues out of some magazines or deal with that slight canting.
To me what it means in this case is oal is in spec but due to variability some are loaded slightly longer resulting in the described problem.
When I reload 300 blackout I work up a load using that reference point as my limiting factor, instead of max spec OAL.
