FN FiveseveN load. Anyone care to offer an opinion? Or more valuable, their loading data? I am thinking about starting with the 40gr v-max and going with Unique since I have 8lbs of it. I have seen a lot of data for True Blue, so that will be my second choice. Anyone have a good subsonic load worked up? I have found nothing reliable about where to start with subs, anything can help.

WOW, after two years i finally found a topic i could reply too with confidence. SO, here we go...

True Blue (TB) is what I use. Lately I used 5gr of TB behind a 55gr FMJ and 5.6gr TB behind the 40gr V-Max. This is just my data, and im still working on the loads, I believe I am far below max with these. For subsonics, I would direct you to fivesevenforums.com, there is a lot of very useful information on the forums and the guys are great.
