The bullet I'm using is a Nosler 95 grain BT. With this bullet and load the rifle is shooting 3/8 inch groups at 100yards.
This is the only coyote I've shot with this load that ran off, that's why I was so surprised. All the others shot with this load dropped dead in their tracks (and that's been many through the years) and never so much as ringed their tail like some do when they are dying.
I'll stick with this load for this rifle and I'm still considering going with heavier bullets in my two 22 caliber guns.
I do have another 243, it's a shorter barrel lighter weight gun that I'm going to try some Sierra 85 grain hollow points in.
