A lot of people use the 87 gr. Hornady, for just about every thing Deer, Speed Goats, Coyotes,never been able to work up a good load with the 87 gr Hornady Sierra 87 gr. never seen them, I like the heavy 105 gr,Scenar in my 1x8, A.I. and the 95 gr.Win S.P. in my 1x10, at around 3000 fps they both work real well for me, on Coyotes,Bobcat,Pigs,Whitetails.
For long range steel the 107 gr SMK is the cat's ass. Rio7
