I have down loaded a few 270's over the years. The cartridge handled the download very well. I will admit that I have not used the factory downloads, but I am sure they would do well.
If it is bullet performance you are worried about, then I would not worry. We had great bullet performance on the rounds that we down loaded. We mostly down loaded 130 grain Sierra's. Tom.
Thanks for your input HEAD.
