I have mention this before....

I use the exact same bullet for either. They are really good in either, too.

The issue being raised is not how well they both do on a paper target, but rather, how well they both do in ballistic gelatin (or more important, how well they both do in bad guys).

It doesn't matter what it will do to the gelatin....if you don't hit it!

PHD™- Personal Home Defense™ lead-free copper vs. DENIM

Yesterday afternoon, we tested 3 of our PHD™ – Personal Home Defense lead-free copper pistol bullets- by shooting through 4 layers of heavy denim, to see if the HPs would clog and not expand.

Tested 9mm-90 gr @ 1,350 fps, .40-120 gr @ 1,200 fps, and the .45-150 gr @ 1,200 fps.

This is why I like Billy Bullets,quality molly coated bullets with no speed limit. A guy I talked with that worked for a bullet company told me the copper coating was to thin on most bullets do to production cost. I don't know that for sure just going by what he was saying. Makes sense to me,Barry's Bullets has a waring not to go over 1250FPS.

Precision Bullets are about the same thing, and his prices INCLUDE the shipping, so they are a bit cheaper.
