5.7x28mm Ammunition
I have the FN 5.7 and PS90.
Like many, I've sought out the 'best' ammo and have 5 or 6 boxes of Elite ammo (as tested by Buffman) and 100s each of the everyday practice FN 195LF, 197SR, + the 198LF (green tip) rounds.
My concern is that I like to have the 5.7 loaded with Elite T6-B or S4M...
