I have had my share of bloodshot meat with every type of bullet. X bullets a little less trouble than most. I would have to say that a 500 grain cast bullet in 458 is pretty easy on meat too.
I have not found a sub 1.5 MOA load since Barnes abandoned the original flat base X bullet. I tried several boxes of the blue coated bullets- several free boxes from Barnes and they wouldn't shoot very good for me. I have a box of 168 TSX that I am loading for a 300 Winchester right now. Headed to the range in about 10 minutes. Hopefully, I will see some improvement.
I don't and won't use an X bullet smaller than 7mm myself. I have seen several fail to expand in the smaller diameters but never in the 7mm and up sizes. I will agree that the medium sized ones are utterly reliable, just not particularly accurate in my rifles.
I have some in 458 but not sure what I would use them for.
