Have taken coues and mulies with several 7mm cartridges using 140gr Gamekings, 160gr Gamekings, 139gr SST, 162gr SST, 120gr and 140gr Ballistic tips and 140gr Ballistic Silvertips, 168gr Hybrid Hunter, 168gr Classic Hunter, 140gr and 160gr Partition. In 270 Win with 140gr SST, 130gr and 150gr Gamekings, 130gr and 150gr Partitions. All of these worked well both on shoulder shots and double lung shots.
My dad and I tried some Speer bullets long time ago and were not impressed.
I prefer Double Lung shots and out of all of these bullets I still use the SST bullets, Bergers, and Ballistic Tips. Have some 150gr ELD-X to try out on the 7mm-08.
I have tracked a few coues deer for a 100 yds and more with well placed shots with lungs turned to smush, they just took off when hit. One with shoulder shot with 3 legs that went over 150 yards and with no lungs left. But most have died where they stood. Mulies are easier to bring down, haven't had one take off after being hit, sometimes a few steps then go down.
My dad knocked down all his elk with the 160gr Partition and the 162gr SST. Didn't track one more that 30 or 40 yds.
EDIT: Forgot to include the 162gr AMax, worked great on deer.
