First big game taken with the 156 gr ULD RBBT in my 257 Allen Mag loaded to 3300 fps. Shot was just over 500 yards. The angle was quartering toward us, bullet landed high on the onside shoulder and took out 8 inches of spine before coming to rest under the skin on the offside ham.
First critter harvested with the 270 AM. My dad took this painted Desert ram using the 169.5 gr ULD RBBT loaded to 3300 fps. This was a close range shot in heavy cover. Range was about 50 yards through both shoulders. Fully exited with a 1.5" exit wound. The ram simply fell in a heap and did not even twitch. Not the biggest but it was a good close range test for the bullet to see how it would perform at very close range at these velocities.
Took this very large Mouflon Ram with my 270 Allen Mag at 610 yards. I used the 169.5 gr ULD RBBT loaded to bit over 3300 fps. Shot was dead on the rams chest and the bullet penetrated to the rear ham. It had pretty much turned into a mangled mess of copper and lead but it had penetrated over 2 feet as well.
This pronghorn much, my personal best at nearly 84" of score was dropped with a single 156 gr ULD RBBT out of my 257 Allen Mag loaded to 3300 fps. Range was just shy of 550 yards. Quartering away shoulder shot, broke the offside shoulder and exited. 1/2" entracnce hole, 1.5" exit.
This is the whitetail I took in Canada last fall while hunting with Richard. Bullet performance was more like a controled expansion bullet then a conventional cup jacketed bullet. About a 1/2" entrance would and roughly a 1 1/4" exit. And that was as it took out the offside shoulder so things held together very well. This busk was taken with the 200 gr ULD RBBT fired at 3200 fps in my 7mm AM.
Exit wound from whitetail above. That is the thumb of the famous bullet maker himself!!!
Russian Bore taken this winter using the 200 gr ULD RBBT loaded to 3200 fps in my 7mm AM. Range was 715 yards. Put two in his shoulder before he made it to the brush line. Full penetration and expansion similar to all other game taken with the ULD RBBT bullets.
You will find that expansion begins at around 6" of penetration with these heavy ULD RBBT bullets. If you want to hunt light to medium game, this should be considered and maybe a larger meplat ordered to promote expansion. For game in the 150 to 400 lb range, these are very hard to beat. Penetrate very well with their high sectional density and very accurate and buck the wind as well as or better then anything else out there.
The animals above were from one calender year of field testing with the Wildcat Bullets on big game. This did not even count all the coyotes and chucks that fell to these bullets.
All of the animals above were one shot kills except the Russian bore but he would have died from either of the two shots that hit his shoulder. Pigs are tough, just wanted to put another bullet in him and was not real sure where my first bullet had impacted. Hard to tell on a dark boar at 715 yards. All I could see was ice crystals fly all over hell when the bullets landed and the pig shutter from the impact.
I will not use any other bullet as long as they shoot well in my rifles. So far they all have but there are some rifles that simply prefer other bullets. Not the rifles fault, not the bullets fault, just the way this game plays out some time.
If your looking for a long range big game bullet then these are very hard to beat.
If your looking for a bullet for use on game such as elk, moose or big bear, I would say these will work but Richard offers other designs that are non-bonded core that would work better. Flat base with heavier jackets to be specific.
You will not be unhappy with the results of these bullets on game even up to 500 lbs with the heavier bullets from the results I have seen first hand.
