So I went to H&H today for the first time in a while and decided to shoot my 155 gr. gold dots I've been carrying for the last 8 months while I was target shooting. Problem is, they didn't have the 155's only the 180's when I went to try and buy replacements. I went ahead and got a couple boxes of the critical defense after hearing really good things about them from a lot of friends who carry with them loaded. It kind of seems like a cool idea with having that insert in the tip. Anybody have experience shooting them as far as any failures? Positive aspects and negatives would be appreciated too. Thanks
