Heavy bullet, slow velocity equals very pitiful terminal performance. I have killed a lot of coyotes and the use of heavy bullets, especially in a 6 br means that you have to hit them perfect in order not to hit them in such a way as to not leade to a lingering death.
You would be well advised to use a 70g Blitz king, 75g Sierra HP, or 75g V Max, Coyotes take a lot of killing, they have an incredible will to live.
I have a friend that shoots wood chucks. He started off shooting a 87g V Max at the chucks with his 243, but too many of the chucks ended up dragging themselves back in their holes...at 343 velocities. He says the bullet is too tough for chucks, if it is too tough for chucks, it will be marginal on yotes.
I will assume that you have a fast twist BR, and the twist does aid in helping the jacket to open faster, but for a yote hunting rifle, the 6 BR has the trajectory of a 45/70. You are apt to miss or unzip them due to trajectory issues at ranges beyone 300 yards. Most of the time when you are calling yotes, you don't have the luxury of having lots of time to range find a coyote and click up your knobs to the distance. When you see a yote, you may have to the count of 3 to kill him, otherwise, he's gone. I say this having shot thousands of rounds in a 6 BR at p. dogs and ground squirrels.
Of course, with perfect hits, any bullet will do. It's your hobby, make it what is fun for you!
