I could type here for an hour regarding the topic. However I have already covered this in several different posts on this site. Look down the list and the next page back and see the comments on bonded core technology.
Bottom line is that after all the expense, anticipation, practice, trophy fees, daily fees, 20 plus hours of travel, jet lag, custom gun work scope and mounts etc etc. there is only one single little thing made of copper and lead that ties you to the success of the hunt and that trophy. And it just left the barrel of your gun at 2000 plus feet per second. The way that 1 dollar bullet performs is 100% of the determinig factor in your success. Your happieness and expensive trophy fee dollars all come down to a few hundred grains of soft metal flying along over 2000FPS. How is that 1 dollar an expensive issue? Your expensive field glasses cannot help, nor can the expensive scope, custom made gun, personally fitted boots, range finder, etc etc. only that $1.00 bullet can determine what your going to feel on that 20 hour trip home. Dissapointment ?.......or pride in your skill and preperation. I promise you after the first 200 yards tracking when blood is getting more scarce you will be saying "what was I thinking when I chose this bullet" How much would you pay then to pick another projectile?
Do the right thing when hunting far from home for expensive animals, or dangerous animals. Use a Bonded core bullet, or if your gun can shoot X bullets well use them. Don't waste your time with a 20 cent bullet purchased in bulk for the hunt of a lifetime. It's not expensive to buy premium bullets it cheap insurance!
