Starline 10mm Mag brass

more goofing around

A more in-depth comparison here. Original version below.

Good folks at Starline graciously supplied a bag of 10mm Mag brass.

I've read that 10mm Mag brass is a bit beefier, though capacity measurements of Starline's Mag version (cut down to standard length) suggests it might be built the same as their standard case.

Wall thickness at mouth:

Standard: 0.0115
Cut down Mag: 0.0095

Good neck tension felt seating a bullet in the cut down case.

All Starline, left to right: Standard 10mm; 10mm Mag cut down to standard; 10mm Mag.

I'll cut some more to standard length this weekend & identical-load some modified & standard cases, see what the pre results are.
