Don't know anything about them or anyone shooting them.
There are a lot of good, well proven bullets on the market that I'd look to before trying something off the wall.
Nosler Partition and Accubonds will certainly do the job for you. Of the bonded bullets, the Hornady Interbond is my favorite and they are back in production at least in factory ammo. Hopefully they'll be back on the shelves as reloading components before long.
The Hornady Interbond is the one bullet that has flat out never let me down on anything, they just work every time if I do my part.
The Perigrine VRG4's worked really well for me in Africa on the elk sized game I shot with them. I also killed a really big boar last week with my .260 Rem shooting the VRG4 6.5 125gr.
They make the VRG4 in 130 and 140gr which would probably work very well for you.
Between the wife and I we've killed 6 deer and 3 hogs, 2 of which were big boars and all were one shot, stone dead kills with caliber sized entry wounds and roughly 2.5-3x caliber exits with the .260's and the 300 RUM shooting the 180gr.
Shooting paper with them I couldn't be happier. Without even doing any load development I'm getting sub .75moa 3 and 4 shot groups from all three rifles I've run them through.
I was a little worried they wouldn't open up enough on deer to suit me but they are really doing a great job.
I thought maybe I'd recover a bullet on the largest boar just due to his sheer size and the shot angle but I checked with the boys at the locker plant today and they said they'd been unable to find it. That bullet passed through the thickest part of the neck, spine, and off shoulder. That's at least 18" of heavy muscle, bone, and hide.
Here's a stock picture of what they look like expanded.
