I do have good records of all 8 bullets Did not post all of the info, I can not type. It took a lot of time to write the artical. If you would like more info on one bullet I will give you FPS. yardage, distance traveled, shot placement, engine room damage, exit hole. recovered bullet weight. No wound photos. I tried to add a photo of last years bull but I only see a box with a red X.
The yardages of the shots, the terminal impact velocity, the location of the hits, and the posture of the animals at the shot, are all crucial to interpret any bullet performance information. I didn't see any yardage information. I have the suspicion that these shots are primarily closer range - less than 400 yards - based on the cartridges and bullets being described?
Interesting information, nonetheless.
Just one quick example that illustrates the importance of providing the additional information. I dropped an ~1100 lb brown bear with a 225 gr Trophy Bonded Bear Claw from a distance of ~130 yards back in 2001. Muzzle velocity from my .338 Imperial was around 3250 fps. Bear was broadside and the bullet impacted the center of the ribcage, behind the front leg muscle. The bullet never exited. It never even reached the far side rib cage. This bear dropped in his tracks without so much as a twitch. He went down as quick as the flip of a light switch. The Trophy Bonded Bear Claw is a largely copper bodied bullet with lead bonded to the copper jacket in the frontal portion of the bullet. A premium 'custom' bullet by anyone's definition. At high impact velocities, these bullets will expand to 1 1/2 to 2 times their caliber width, and they often retain 85-95% of their initial weight. This bear went down so quickly that I was wondering if I had accidentally 'brained' him. Examination of the carcass during, and after skinning, confirmed the bullet hit as described above. At 700 yards, a hit with the same bullet, in the same location, likely would have led to a much different result - at the much slower impact velocity.
The photo is of last years bull. Rich I do live in Co. I used 22 kills to pick the data.
90 to 170 yards had the most kills.
Broadside shots in the ribs and through the lungs.
VEL. 2971 to 3093. all 180 grain bullets.
Three kills with each bullet except the solid copper bullets only one bull was in this group.
Five bulls have been shot over 500 yds 640 is the longest shot.
Some of your findings do not surprise me at all. The thing though is, you need to organize your findings as others have said. As long as you are armed with undisputable facts, tell us the bullets used, not "custom bullet". What cartridge was used, weight of bullet, velocity from that gun, and then distance shot. My guess is, most of your guys are using the '06, and only one or two use magnums. Core Lokts are great in mild rounds like the 30-30, 308, '06, etc. Even up to ballistic tips. I wouldnt be afraid of the BTs with our '06 for elk. I would not use them on any of my magnums, ie 7mm rem mag, 300 win, 300rum, and probably not the 375H&H on anything nasty at least. Im loading partitions in all of those I just listed. Ive used it in my 7mm for years, and never tracked a deer yet. I havent heard many detractors of them or their super cousin the Swift Aframes. Any of the bonded bullets I think are too strongly made to use for standard chamberings, or low velocities. I am betting your data backs this up.
All I know is I have used my 300wsm with 180 gr TSX for elk, bear, deer, and antelope. I shot the deer at 75 yards almost end to end, ended up under the skin on the long shoulder, perfect expansion and mushroom, nose in the dirt almost instantly. The antelope was 327 yards, I hit the shoulder and you could see thru the animal, the bear was 138 yards thru both shoulders, perfect expansion recover on out side of bone under skin, perfect mushroom, and for my elk, he was 386 yards, my first shot was low and back, he only made it 100 yards and bedded giving me a quick finish up shot. The elk got real sick real quick and the bullet made up for my bad shot. Last year I used the new 80 TTSX out of a 257 weatherby and at 284 yards, bang, no flop, just dead antelope!
That said maybe others have had not so good luck with Barnes, but I have had great luck with them, I thin it is like anything else, if you have confidence in what your using it makes a big difference. I have been impressed with the trophy bonded bear claw and may try one soon.
On another note I used the 150gr GMX on both of my spring black bears and although the shots were close 25 and 20 yards the bullet killed them almost instantly and the wolf I shot at 200 yards dropped like a rock, all with a single shot 308.
My best performance on deer has been with BST out of a 270, 243 and 300 wsm, took my first goat with a 243 wssm 85gr BST and he dropped in 2 steps. I hunted with a guy 2 years ago and he used the 180 gr BST which is built stronger for big game and at 100 yards his bull only went 50 yards, but not the round I would want for a strong quartering shot or long shot when I need to break shoulders. My wife shot her antelop with a 243 using the SST and I was not impressed.
I think the power points, corelocks, are good for deer and behind the shoulder shots on black bear at reasonable ranges, but I will take my TTSX for Elk/spot and stalk bear or big mule deer.
