What are you shooting? That would help a bit.
Matchkings typically dont give much expansion, AMAXs and VLDs are much more explosive IME. I said "typically". SMK's are a good bullet dont get me wrong as I do use the 300g SMK in my EDGE, but there are better target bullets now a days that do a better for killing game, in certain calibers anyways. SMK's behave unpredictably a lot of times, as since they are not really designed to be used on game, therefor sometimes they open up, sometimes they dont. In my findings however, the AMAXs and VLDs tend to be much more consistent in how they behave. They tend to open up everytime, and sometimes to much, but either way, they open up.
I have a few calibers for yotes depending on how I'm feeling, If I'm calling or driving around, etc. Either way, LR yote bullets almost always consist around a plastic tipped bullet of your flavor. There accurate, have relatively high BCs for hunting bullets, and they expand EVERYTIME. I like NBTs and VMaxs for hunting bullets, and AMAXs for a target/hunting bullet.
In a 22-250 or swift, id use a 55g or 60g NBT/VMAX, in the 6mm flavors I'd use a 87g VMAX or 105g AMAX, in 25's I'd use the 115g NBT or 115g VLD. In my 264 I'm running 95g VMAXs at 3475fps which will work pretty good to 700 or so, but after that I need to work with the 123g AMAX for the ones that are waaay out there.
I do use the 300g SMK in a 338 EDGE at 2825fps and have shot at a coyote with it about 100 yards, looked liked a bomb went off in his chest, bout a 6" hole. Buuuuut, thats a hunk of lead moving right along so it tends to put a pretty good size decent hole in anything it hits
I shot another one about 100 yards with 250g SBT at 3050fps in the neck and it was hanging by the tops and bottom pieces of skin.
Just depends on what exactly is LR to you and what cal your shooting?
