well thats a good question but since everyone and their dog has got an electronic caller around here and im just getting into the calling thing so the coyotes are call shy and i dont plan on shooting a coyote at or beyond 400 everyday im just saying that i want to put a load together that will work good for the 200-350 yard shots and the occasional 500 yard shot. And i like to shoot for fun so i set up coffee cans at lond range and shoot them on nice days. and no offence takin.
Come to find out my .223 NE has a 12 twist, so the 70 keyholed at 50 yards, all over the place at 100.
They would have made a great long range coyote load.
To be honnest though, the best bullets are thin skinned ones like the Hornady Vmax, Sierrra Blitzking, Speer TNT and Nosler Varmit Ballistic tips.
Berger Hunting VLD's are ok, they have thin jackets, but not as thin as those real varmint bullets.
And most the time the Bergers will do ok, but other times can pencel through and dog runs off 20 miles.
I switched from those 70 VLD to 55 Hornady Vmax bullets in my .223, gets around 3100 fps.
the Best one is the new 53 grain vmax, has a boattail and a bc of like .290 (good for a .22 cal)
at 400-500 yards the 70 Berger might have more speed, but the fradgile Vmax will still expant/blow up inside of dog.
even with less speed and energy, I'd bet the 53 Vmax would have more % kills than the 70 Berger even at 500 yards. Bullet performance sometimes beats out numbers, now for deer sized animals, the VLD's usually always expand.
Run off are VERY VERY rare with Vmax on coyote in any caliber from 22 centerfire on up, same for the other ultra thin jacket bullets,
