I researched this quite a bit...
when I went through my concealed carry training. One crucial element of carry ammunition which often gets overlooked is muzzle flash. Someone had tested federal, triton, proload, and others for functioning, accuracy, and muzzle flash. Proload won the muzzle flash category and overall. Remember, if you shoot at night, and you have a muzzle flash that's intense, you'll be instantly light-adapted and be relatively nightblind. You want the least muzzle flash possible. I have been very happy with Proload. I would have to agree that it outperforms Federal which is what I have directly compared it to.
Hope this helps
