DeadBlow Hammers are Hammer Hunter™s that are designed to retain 40%-50% on impact. They simply have a very deep hollow point that causes them to shed much larger nose petals. We have a full line of these ready to go. I just have not had the time to get them up on the website. We hunted with these bullets last fall in MT and had very good results. I’ll be honest, it is not exactly what we think a bullet should be, but we are looking to satisfy those who like a frangible bullet. Because they are pure copper they do not disintegrate like lead core bullets, so meat damage is still very light. The shed weight comes of in a few large pieces that do their own work. Think of 4 little 25g bullets along with the retained shank all penetrating deep in the animal. On game performance was actually very good. These bullets will be a bit more expensive due to the fact that is takes so long to drill the deep hole. If anyone is interested in DeadBlows shoot me a note. We can fill orders I just need to know what you are after.
