Mike that function test looks great - couple of questions if I may:
Have you repeated that function test with flat nose Eley ammo?
Can we get the height dimensions of the new mags? 10, 12 and 15?
This will allow a direct comparison with current std nylon mags as well as ones using extenders.
Reason is overall height can be a factor in PRS style shooting and may influence my choice between 12 and 15 rounders.
Thanks again for all you efforts in this arena!
