what grain ammo is to high to use in a 380 and 9 mm. thanks.
+P is not good for them! What do you shoot? Guns or ammo?
all i am using is fmj, just not sure waht grain is to high.
If all you are using is FMJ, there is no such thing as too heavy a bullet. You're not going to find any manufacturers who make bullets "too heavy".
