Neat looking bullet structure! My old 180gr reloads had 7.8gr's of WSF... I kind of doubt these hitting 1200 FPS.
I just sent 10 10mm tango thru my EAA witness on my RCBS chronograph from Basspro, my results:
1440fps, 1445 fps, 1454 fps, 1471 fps, 1437 fps, 1441 fps, 1489 fps, 1477 fps, 1477 fps, 1471fps
color me impressed either way
How does that compare with my average?
