I know this thread is old, but it is the most on target on what I am asking.
I am interested in the tests/results of Cor-Bon flagship 9mm bullets; SD09115 and SD09125.
I am surprised to see the heavier (147g) bullets for 9mm being so highly rated now, I remember them not reliably expanding, especially from less than 4" barrels.
Can you please enlighten me? I currently use the SD09115 in my Kahr cw9, and my larger pistol. And I would like to understand how this round is lacking and why when moving to another round.
Thanks in advance!
