I also do not believe their B.C. specs given the shape of those slugs and the velocities they are shot at. The HIGHEST BC shape for any slug running sub sonic is a perfect ball end round nose. Also, nose heavy slugs are more stable at those velocities which is why the most accurate air rifle projectiles are hollow based.

Are you sure about that? I've shot groups with a 300 whisper and a 240 gr matchking loaded subsonic that are in the 1/4 moa range at 100 yds. I've also shot some might small groups with truncated cone wadcutters shot subsonic from revolvers.
Perhaps a better statement would be that for a relatively light for caliber bullet the hollow base has an advantage.
Ballistic Coefficient has nothing to do with bullets ability to group tightly at a fixed distance. Period.
BC, is measurement to calculate relative drag .It has to do with drag and thus, velocity retention . A sharp nosed bullet can group better in an individual rifle, particularly at relatively short range, and still loose velocity faster than a more blunt nosed slug that may not group as well in a that particular gun.
It's one of the reasons why the long range snipers and match shooters are so sensitive about keeping their bullets ABOVE transonic range in flight at the ranges the engage targets. And why for years they have felt the .308 is on the ragged edge in that regard past 800 meters.
My point is that Crosman is crowing about a new 9mm airgun that breaks rules of airgun ammo ballistics even THEY have followed with other match grade airgun ammo that operates at less than 1,000 FPS. Compare the basic shape of the new .357 Nosler airgun slug to the very highly thought of Crosman Premier Match Airgun pellets- apples and oranges -Why?
Marketing gimmicks- same as the "Mall ninja" AR -15 looks of the .357 rifle.
Of course, it will take a lot of gimmickry to sell such a "practical" air rifle that is useless without batteries,is a "Compact" 48 inches long, weighs a "handy" 9 lbs without scope and is going to be "reasonably priced" at over a grand..LOL
