What are the case dimensions of the 7.62x40 and capacity compared to the 300 Blackout? What pressures are both rounds loaded to? How deeply does the 150 gr bullet intrude into the powder space? Which 150 gr bullet is used, is it a flat base or boat tail? With a twist of 1:11 or 1:12, does that mean this new round intended to run bullets of 150 gr & less? Has the 7.62x40 been submitted to SAAMI? The blurb states that the factory ammo will be fire-formed upon firing to give an additional grain of capacity. Where does the factory case headspace? When fire-formed, what changes? Does the fire-formed case have less body taper and/or steeper shoulder angle?
What has been posted is a lot of advertising hype with very little technical data
