I have a great load for the Barnes 160 TTSX and a friend of mine has used the Barnes 185 TSX factory load on a medium sized elk just fine. My SIL used the 185 TSX on mule deer up close, no bloodshot meat (lung shot). I have a bunch of Speer 200 HotCor that I have plans to load/use for practice, but I also have some Nosler 180 Accubonds. I've used the older 210 XBT in a 340 BEE and the 185 XLC in a 338 Win. I have read good things about the 210 Partition and while I'm sure its very good, is it really any better than the 200 speer at 338 Federal speeds?( I loaded this bullet for a friends 338 Win and it was very destructive on little Texas deer.) I can load to 2.87" in this Hawkeye, so the 210 TSX should fit OK, but will it really do any better than the 185 TSX or, for that matter the 160 TTSX? My future holds a better promise for big hogs more than bull elk, but late season cow elk are still on the menu. All opinions welcomed. ( I must mention that my Whelen AI is always first up for me, so I know there are better calibers, but the 338 Federal has got to be a good one under 300 yds for about anything, IMO.
