Well I Picked up a box of federal fusion 150 grain ammo, this ammo chambers just fine and extracts fine. Today when I get home from work I'll try and fire a few of them and see how they extract. One thing I did notice this type of bullet does not load very smooth out of the mag the bullet point seem to catch on those sharp edges right below chamber. Anybody else have have this trouble, if so what did you do to solve it? I have a new mag coming, could be the mags not sure yet.
