The Hybrid's were developed as a pesting round for birds, and work well there in any caliber. I would be hesitant to use them on anything larger than a ground hog, and with headshots for the win. They probably would not hardly twitch after the concussion of a .30 Hybrid opening up in the dome! Because coyotes don't go underground or up in trees when shot, the Hybrid would put one down but they may run for a ways first. I'd be more inclined to get a heavier slug for them or use the proven Hades pellet. The way they tend to open, they cut their way through instead of just mushrooming into a bigger round like most slugs do. Momentum is the going to work in your favor there as well.
I was doing the numbers for 100 yards with the .30cal Hades vs the Hybrids and the Hades just shed so much energy at 100 yards I don't know how effective they will be.
The first row is 50 yard results and the second row is 100 yard results. With a starting velocity of 930fps, the FX Hybrids keep over double the energy the Hades do at 100 yards and 50% more energy at 50 yards.
I got the delta of velocity numbers from Shooter1721's YouTube channel and used those to generate a Ballistic Coefficient for the Hades at .025, which is pretty bad, as JSB Exacts are .040, and the FX Hybrids are really good at .1, while the NSA 54.5gr .30cal slug has a BC of .12.
That keeps the Hades as an under 50 yard round for me, as it's shedding too much power to be useful any farther out.
I agree that the Hades is a short range pesting round. Any longer range hunting or target shooting and I use heavy NSA swaged slugs for the retained BC. I do want to test the Hybrid design with the large hollow cavity in 357 caliber. At airgun velocities, because of the weight and large hollow cavity, the energy transfer and penetration would, in theory, be great.
