Those are a double H.P. design.
I have hunted coyotes since the late 70's, killed a lot of them, and seen a lot more killed as we hunted 4 guys in the truck, usually.
A bullet that does not expand quite so rapidly does better on quartering shots from the rear and from the front. Also, you have to consider hitting the thick part of the upper rib or the shoulder scapula.
When the bullets are rated at 3600, you are dealing with a fragile bullet. It would be easy to swap that bullet for others that are not as fragile.
We tried all kinds of bullets when we were hunting in Mexico where the predator numbers were very high.
Bullets that performed very well in the 22/250 were as follows:
Sierra 45g High velocity spt rated at 4000+ fps
Sierra 50g Spt
52g Sierra match hp
53g Sierra match HP
Sierra 55g spt flat base
Sierra 55g bthp, tough bullet
Sierra 55g btsp
55g Nosler ballistic tip
55g Hornady sp with the cannalure, very accurate bullet
55g Sierra semi point
55g Winchester
63g Sierra semi point
All bergers from 52-60g worked very well, so did Watson 52g hp
I had Speer 52g HP blow up on the surface at 15-65 yards with a MV of 3600 on one hunt. We had to aim for the head and neck after having multiple coyotes get up on and try to hobble off. In Mexico, multiples on a stand is expected where 4 coyotes is not uncommon and our all time record 1 1/2 hour stand when it was lightly snowing south of Nogales was 17, barometer in the truck indicated the barometric pressure was dropping like an anvil.
60g Sierra penciled through at 3500
The bullet is the cheapest part of the hunt, so use a bullet that will penetrate on a Texas heart shot, and call it DONE!
All bullets made on J4 Jackets 60g and under worked well for us, no matter what the maker.
I shot a lot of Calhoon's bullets on ground squirrels and p. dogs. IF those bullets had a hp size of a 52g Sierra match, you would be in business as the jackets are thin and the core is pure lead.
If you ever see any, the Speer 52g Match HPBT is one heck of a coyote bullet, duplicates the Sierra 52g bthp in shape and length, but a tad more fragile....works well.
Our worst trip to Mexico for the weekend was 13 animals picked up, and the best was 57. We drove down to Hermosillo in the state of Sonora to shoot doves and pigeons and killed 223 predators in two weeks. Lots of different kinds of bullet testing. We would shoot 25 straight with one kind of bullet to see the effect of different angles and ranges.
Today, The dove and pigeon shooting down there is still spectacular, but today you have to use their guns, they pick up up at the airport under guard, and you are under guard the entire trip. These trips are much less expensive than going to Venezuela. You will shoot till you get tired of shooting doves and pigeons, and the spotted bass fishing is incredible!
