It sounds like the one bullet you are talking about might be an XTP it is a good bullet especially below 100 gr of powder. Remember bullets that are not bonded tend to splatter at high velocity. If I had to use any power belts I would fill the hollow point wit a screw or solder.
When you stop and think about it for up to 150yd the Gold Dot or deep curl as they call them now is the best for deer and has a much better price than most of the other decent bullets.
If I need to shoot long range I use the Bonded Shock Wave the always do quite well for me.
I tried them fancy copper bullets a few times but had them fail to open on a long angle shot, I do not pay those kind of prices for something that does not work 100% of the time.
