87Predator: Using 80-90 gr bullets I have had the best luck with my .243 AI's with the 87 gr V-max and IMR 4350 powder. The 5 shot groups run from just under an inch to 0.014 (yes that is right, only once, but had a witness). Most of the time they run 0.500 to 0.750 more than enough for coyotes out to 400, P.S. they are NOT fur friendly. The speeds for my best group's run `3150 to `3425 depending on the firearm. I have a Winchester 1:8, Remington 1:10, and (2) Savages 1:10 in .243 AI. I will buy 1:8 from now on.
