It also depends on what you use them for; I like the FTX for gong and Knockdown shooting and the Gold Dots and Lehigh for hunting. I even like the 245 PB for coyote hunting they really smear a coyote. If we all used the same thing some people would be out of a job. I used to use XTP's and still have about 500 of them 250 gr laying around and if I had a hard time getting bullets I would not even think twice about using them. Most bullets will do the job fine, some of us want the deer on the ground in a hurry some want that hole coming out the other side to be sure of a good blood trail. I think the most important thing is hitting them in the right place and getting at least enough penetration for a clean kill. I personally have never tried the copper bullets but its clear they will do a good job because a lot of people get good clean kills with them.
When we discuss bullet structure and what this one or that one did under certain circumstances its not a criticism of what some body uses; its just data that we are trying to understand and assimilate so that we can make better choices.
No one should feel that we are attacking their choice.
