More fresh .45 Super data from Gen4 G21 w/4 port KKM barrel (barrel itself w/threading is 5" long)

New Starline brass and CCI LP:

230gr FMJ, 9.5gr Longshot @ 1.250": 1,185 fps (15 fps ES!!) That's 717 ft-lbs!

230gr FMJ, 9.8gr Longshot @ 1.250": 1,229 fps (37 fps ES) That's 771 ft-lbs!

"255gr" Beartooth WFN, 9.0gr Power Pistol @ 1.175": 1,179 fps (13 fps ES!) That's 772 ft-lbs (it really weighs in at 250gr, not 255gr)

"280gr" Beartooth WFNGC, 8.0gr Power Pistol @ 1.180": 1,065 fps (24 fps ES) That's 693 ft-lbs (it's a 275gr, not 280gr)

Notes: brass looked good on all loads. I had no previous data on the 280gr WFNGC, so I used 8.0gr. I feel 8.2gr would have been safe, even possibly 8.4/8.5gr. That should get me the 1100 fps I'm after, but I'm not disappointed since 1,065 fps is pretty close and it's still gonna kill quick and penetrate well.
