I was looking at Hornady's Critical Defense FTX video online and got this idea of putting GOOP contact adhesive and sealant in the hollow of the HP. So I did. the GOOP will settle over night and alittle more needs to be added the next day. after 24hrs. I trimmed the excess GOOP off so bullet will have a flat top. The GOOP still has some flex to it but defenatly sticks to the bullet. Now I need to talk to the range owner and see what we can come up with to test it. I'll be using .38spl., .357mag and 9x18. I'll get pictures of bullets to post. I'm open to all opinions on this.
