I have not seen the problems you are mentioning. I shoot lots of hogs each year, and there is very few animals that have as thick of skin, and I get pass throughs ever time on double lungers with expandibles. That is unless I hit the back shoulder blade, but then agian, I have had my 300 wby stopped by the back shoulder on a hog. And if it stops a 180 grain bullet cruising at 3200 ft/sec, then it is no wonder why it stops an arrow. (I cook my own bullets and cronie them)

.
Too each his own. What ever works, keep using it. Im just not ready to dam expandibles. I did a lot of that when they firstcame out, then I broke down and tried them.
