While not the 144, my experiences with the Berger Hybrids have been as follows:
Berger Factory 105gr Hybrid 6mm Creedmoor ammo. I used this ammo all through 2020 for culling deer at night over soybeans on permit, for coyotes, and for hogs. I probably took at least 80 coyotes with this load, a number of deer and pigs. Longest coyote shot was 793 yards and the longest deer shot was 819 IIRC. For me, this bullet was a death hammer. It performed extremely well. I would say the average shot distance for both was between 400-500 yards. Most of the deer were DRT and few ran more than 100 yards. Most all the coyotes were dead within 20 yards from the POI. I shot a boar at over 500 yards and he just fell dead. No stinky leg, no thrashing. Just like you turned his switch off. He was sneaking along a creek bottom with a group of cattle. Actually standing right beside a cow when I dropped him.
Berger 130gr Hybrid loaded in FGMM, 65CM. Seemed to perform on par with the 105gr. Had very good results the few animals I killed with it. I would say if I had more of it to play with, it would be my go to load in the KAC.
Berger factory ammo, 65CM 140gr Hybrid. I will not use this on coyotes again. It penciled through and most ran much farther than I like, even with pretty solid hits. Several required anchor shots after the intial hit. I do not like that. If I can anchor the first coyote of a pair DRT with the first shot, 9 times out of 10, #2 will run about 150 yards, stop and look to see what happened, allowing me to shoot #2. If they don't do that they will do a 70-80 yard circle and come back to #1 to see what is up, allowing for a shot. If #1 bolts after being hit, screaming as it runs most of the time #2 will not stop until they are into the next county. It did do ok on hogs though.
I have a bunch of 109gr hybrids for the 6mm CM I plan on trying, but my gut says they will not do as well as the 105's.
While I do have a good many spots I hunt with some fairly long shots, upwards of 1200 yards at a couple, most of my hunting is at night. We rarely have winds at night over 5mph. So I usually just run the 6mm CM. If the odd hurricane or something rolls through giving us a bunch of wind at night I'll put the 300 NM barrel on
