Thanks for your honest post and info to help us all learn more. Will you do us a favor and use a welding tip cleaner and clean out the tip of 2-3 bullets and then shoot them at a 1 gallon jug again. At least 2 or 3. Let's see if cleaning out the tips helps them expand on a 1 gallon milk jug or not. I believe a milk jug is similar to a lung hit between the ribs. If it still doesn't expand, we will know that particular line is bad for hunting. If it expands we will know we face to clean the tips out. Either way it will be useful for all of us.Ok went and looked today and found nothing, but it's so thick you can't really see much. I did shoot a gallon milk jug at 300 to see where I'm hitting. Shot twice because I thought I missed the first shot. Upon checking the milk jug, the water was drained and both bullets left tiny tiny entrance and exit holes in the jug. Every time I have shot ELDX at milk jugs the jugs exploded. I'm not to happy with these bullets for deer. Great for paper but not an animal.
