FWIW I have shot quite a few of these rounds - when the supply ran out I was able to duplicate it fairly well using the Lapua projectile & 11.5 grains of Trailboss powder.

the COAL is 2.625" and the powder seems to be packed fairly tight. </div></div>
IT is VV N310 I used the same powder for years in my subsonic. about 9.5 w/ a 180 gr. Hornady RN. Use a Lee Factory Crimp die. Much more accurate.
yes it is a pistol powder,but so is trailboss. It is one of the fastest powders out. like #3 or #4 it works quite well but with Trail boss, it may fall to the wayside. Mike
