Not to hyjack but I would think the Sierra 85 HPBT would be a good combo coyote/deer bullet? I used the 90 NBT from a 6mm/284 on a pronghorn and it was pretty nasty! I think it would also work well on coyote/deer in the 243. I only used the 90X in my first 240 wby, but it killed a big coyote easily. A second one used the 95PT. Many around here favor that 80 TTSX in the 243, etc,, but I don't normally use any 6mm for deer/antelope anymore, but when I did I used the 85xbt in the smaller 6mms. I do try to work on coyotes as much as I can...Back in the early 90's, I met two brothers out here who used the Barnes 100X in their 243s for elk! I have another friend who only uses the Hornady 100 SPBT in his 240 wby. He has killed many elk with it too.
