ATF may not realize that either. 
...contained a soft steel core but has seen changes since including hardening. While named 5.45 mm, the round actually measures 5.6 mm. This leads in an interesting direction. 5.6 mm is greater than 0.22 inches, less than 5/10,000 of an inch greater but theoretically greater. Inferring manufacturing standards needed to ensure that most of the time the diameter of the bullet produced would be above 0.22 inches implies an accuracy of about 1/1,000 of an inch. Sounds realistic to me. The presence of the harder core along with the theoretical size of the bullet leads me to conclude that the ATF restriction holds some water.
Is new enforcement of this somehow coincident with the sanctions targeting Russia? IMHO, yes. If a means to further such can be found, then the search for potential "targets" can be inferred to be related.
On another front, if one looks at the law and its intent, considering .22 caliber would equate to any diameter theoretically less than 0.2205 inches. I remember proposed laws that name the very common Remington .223 without being specific about that bullet's actual 0.224 inch diameter.
IMHO, the basic intent of the restriction, as written, constrains the import of "armor piercing" ammo larger than what is commonly accepted as .22 cal. In my opinion, the restriction should not ban the import of 7N6.
Now let me go update my blog...
...you Jell-O balloon cat.
...Smokey Yunick v Bill France days.
(The part of Bill France is now being played by the ATF)
Brings back memories. Made me think of old Grumpy Jenkins.
Grumpy's toy:
Sure was fun watching that little smallblock vega beat up on Sox and Martins noisy big block mopiles.
Smoky was a character. Both of them were.
