Winchester White Box and Fenix .45ACP FMJ Range Comparison
Used two pistols: Glock 41 & Kimber Pro-Carry II. Both brands fired from both pieces at the same distances, same round counts, and same temperature (cold barrel, cooled barrel, and hot barrel).

Kimber Pro Carry II - 25 yards - Fenix and Winchester 230gr FMJ
Bottom line: I'm happy with all three of my practice ammunition brands (Winchester White Box, Freedom Munitions, and Fenix); not a real discernable difference in their performance when one takes the shooter and distances into account.
The only real nit I have to pick with Fenix is that on their web site from which I ordered, the 250 round order implies 5 boxes of 50 because of the picture shown. When I picked it up, it was in a heavy plastic bulk bag. A bit more tedious, but that didn't affect performance.
