Would have been interesting retrieving those examples...

You can see how those turned projjies have 3 driving bands...interesting

Mass factors in favour of a projectiles BC, relative to the SD; lightening would reduce the BC for a given form.....

Brain starting to hurt....

These projectiles have achieved 2" groups at 1000 yards so are reasonably accurate.

Just "reasonably" ?

You've got high bloody standards

Hard to tell if the AMAX core is cast or machined, based on a retail cost of $4.20 each they might be machined.

Looking at the cutaway 1290 posted the top of that core is looking a bit sloppy....

Right side of core in particular in relation to the copper jacket.
