Work to this load in your rifle, I have one barrel that maxed out at 44.5g but was very accurate at that load at 3300 fps.
I bumped shoulders every firing with a Forster neck sizer, and get 12 firings out of a case.
I have shot several bullets over the years, but usually did not have a dual purpose for deer and coyotes.
85g Sierra bthp has been a stellar bullet, small groups, and R#19 again rules the day. I shot around 44-44.5g of R#19 with this bullet because it had more bearing surface than the Speer btsp, each bullet will have it's own requirements.
The 95g Ballistic tip is a tough bullet, I never shot them on coyotes, but shot the 95g and the Black coated 95g Noslers in the 243. I love the black coated bullets as the coating reduces pressure dramatically and was able to achieve more speed with accuracy.
The 243 is an easy case to work with, no need in having a do it all load but that is just me.
I will say this, with 85-87g bullets, IMR 4064 will produce some incredible accuracy, BUT R#19 will be about 200 fps faster. I used F210's with IMR 4064 and Winchester large rifle primers with R#19.
The Hornady 100g BTSP and Flat base are very, very good bullets for both coyotes and deer. My family has killed a house full of game with this bullet ranging from 40-41.5g of IMR 4350 depending on the barrel. This load is an excellent hog bullet also. I love the flat base version of this 100g Hornady bullet. The 100g Hornady does a good job penetrating shoulders and pretty good on quartering shots, only the 95 & 100g partition is better in the cup and core bullets.
With any of these bullets, and even the 70g NOsler ballistic tip, they will kill deer with extreme prejudice when the bullet is placed correctly. Quartering shots, running deer can produce tremendously difficult tracking jobs in thick terrain. So, pick your shot.
When ever you shoot deer in the lungs, expect them to run. If running deer are not what you want, then you have two options, neck shots or shoulder shots.
Last year, my cousins used the 95g SST after recommendations from a friend in New Zealand that uses them on those large deer they have. We had very good luck with the 95g SST with 12 deer accounted for, with small children taking their first deer. Some barrels like a flat base vs a boat tail bullet, this is a great choice for that application.
It would be interesting to hear from some of the California boys and how their 80g tipped tripple shocks are doing on coyotes. I worked up a load with them and never killed anything with it.
