I was at a gun show today in Sacramento and I purchased some Gold Dot Hollow Points. Previous this, I had assumed that all factory manufactured ammo that bore the "Gold Dot" name was produced by Speer. Oh how wrong I was. I asked the guy for some 124+P, all he had were 124s. So I bought some. The box he gave me to look at looked like a generic white box that said "9mm Gold Dots" on the cover, and I forget if it had said "Speer" on it or not. Anyhow, I buy the damn ammo and when I get home, I open the box, look at the ammo and its all marred up and dirty. Turns out to be re-manufactured MiWall ammo with Gold Dot bullets. I feel ripped off. I should have paid closer attention to what I was doing. Anyhow, are these Miwall hollow-point Gold Dots any good? Should I use them for defense? I'm on a tight budget and I got them for a good price ($20 for a box of 50), but I don't want to burn through them for target practice. What kinds of velocities and energies do these bullet generate?
