My experience is limited to Nosler Accubonds and that is only a few animals. What adre your experiences with the various bonded cup & core bullets?

Nosler Accubond
Hornady Interbond
Swift Scirocco
Swift A-Frame (not a cup and core though)
Speer Deep Curl
Trophy Bonded Bear Claw
Norma Oryx
Woodlegh
North Fork

May be others I missed.

Really, most of those I would not deem cup/core bullet. I love the NFs, only hunted them in 404 though & now they are just too pricey IMO. I feel the Hornady over expands & reduces penetration at least for larger game. I would use any of htem w/ confidence though.

Swift Scirocco are too soft, lack penetration

A few years back a friend of mine shot through an antelope at 400 yards. The 165gr Swift Scirocco shot clean through, the long way.

For the most part they are not needed for the task at hand.....usually deer hunting!

That said....I've used Remington Ultrabonded, Swift Scirocco, Swift A-Frames, Accubonds, and Interbonds and I like them all.....

Even when they are not needed, they allow me to use a slightly lighter bullet which allows a little better velocity and hence a slightly better trajectory! and yes....I just like using the best....with in reason for cost! I've yet to recover any of the bonded bullets....they seem to pass through.....as I want them to do!

to be clear.. deep curl is nOT bonded cup and core - its thickly PLATED onto the core, not a bonded cup and core at all.

Not a direct answer to your question but I've had perfect perfomance from conventional .24 and .30 cal cup and core bullets on deer and smaller so I've never bothered to even test premium bullets.

Norma oryx works well on moose and boar in non magnum calibers.

This discussion started an THR, I finally got rountuit on Thursday.

Last month a thread was started about deep curl bullets. I said I'd try some in my expansion testing tubes. Well here's the first one, a 308 caliber 165 grain from a 30-06. Rifle used is older than I am,(66 in jan), a 03-A3 springfield.

Here's a few pics;





Notice how the lead has clung to the inside of the jacket. That's what meant by "BONDING". There can be no doubt that the deep curl bullet is truly bonded.







Penetration was completely through an out the end of the 10 inches of the expansion medium, a soft wax. The guys at the bullet test tube website say that a standard rifle size test tube will stop a standard caliber like the -06. Well, I had to devise a backup plan. I made a coupler to attach to the back of the test tube, another section of 6" tube stuffed with rags. The rags are tough for a bullet to penetrate, especially one that's fully expanded and slowed way down. The bullet was just inside the first layer of cloth, an old "T" shirt.

What was the results? Since this was my first time using this medium, I can't say I was impressed with the wound channel. It is quite narrow. The expanded bullet weighs out at 122.6 grains. Meaning it lost 42.4 grains. The wound track shows shards of lead which could be left behind in meat. The expanded slug is .650 across it's widest point.

Penetration was good. I would say bordering on excellent. But I may find out that all standard rifle bullets will go all the way through the test tube. I also tested a .223 60 grain nosler partition. That's a subject for another thread, coming soon. I also have several other "hunting weights" to test for .223.

Velocity was an estimated 2650, the tube was at 25 yards. Why not 100? Because the Springfield has irons on it, these tired old eyes can't shoot irons that far out.
