GPO I know its hard to lose an animal, and probably 10 times as hard to lose 2. However, I ran an outfitting business for many years and shot control for many years as well. I hunted for a living. Your post has a lot of clues in it for those who now what to look for. I personally tracked every deer that my customers shot over the years as well as my own. It's understandable that we as humans want to look for something to lay the blame on when things don't go right. The BULLET or cartridge is usually the first thing we blame unless we have a guide handy to blame.I had a rough week last week with my Tikka 260 Remington and the above bullet. I loaded it to 2790 fps with one hole accuracy at 100 yards. I shot two deer last week and the results were terrible to say the least. First was a medium size 4 point at a lasered 176 yards. the shot was good but a little back of perfect. It was spotted by two friend with binoculars. The buck hunched up and almost dropped, then trotted into the woods. We gave it an hour and then tried to trail it. No blood what so ever. Plenty of hair, but nothing else. We never found any blood nor any sign of the deer.
The second was a nice 9 point shot a a lasered 213 yards. Again a buddy was spotting for me. The shot hit perfect broadside. The deer dropped and thrashed on the ground. Finally it rolled on its stomach. We were sure it was down for good. I was about to fire an insurance shot when it suddenly staggered to its feet and ran into the woods. We waited and hour and fifteen minutes and started trailing it. We never found a large pool of blood, but there was enough blood to easily trail it for at least a quarter mile. After that there was nothing. We got several dogs out to try and find it but nothing. We were never able to find any sign after that. Needless to say, I'm pretty disappointed in the performance of these bullets.
Both shots were good, with the second being almost perfect. I killed several deer in this area last year with a 25-06 and Sierra 117 bullets. Almost all dropped on the spot. the one that didn't left a blood trail that lead us directly to it. So, what other hunting bullets would you guys recommend for this type situation?
Your post illustrates several things.
Deer #1.
Deer HUNCH when they are hit in the GUTS. Deer don't bleed MUCH when hit in the guts. Any deer you hit in the heart/lungs at 200 yds is not going to run very far with anything coming out of a 260. Even if the bullet blew up or penciled, the deer would be dead within a reasonable distance. Remember HUNCH=GUTS. Maybe GUTS and VITALS but guts are involved in some way or another. Add in the lack of blood and it equals GUTS.
Deer #2
Deer drop fast and thrash a lot when hit HIGH near the spine. They only get up afterwards when the shot hasn't hit the heart/lungs. That thrashing if he was hit in the lungs or heart would have drained his blood pressure until he blacked out. It rarely happens but I have seen bullets hit the DEAD ZONE or the area between the diaphragm and the spine, knock the animal down and then it get up. VERY RARE and some will say impossible but I have seen it happen twice in thousands of kills.
Over the years I became really good at both blood trailing and STORY trailing. I had to be. Shooting a critter is an adrenaline filled rush for most and things get confusing. We SEE things we want to see not necessarily what really happened. Before I began to trail a deer I would spend a long time deciphering the STORY.
I know its hard to hear this but 99.99% likely the 1st deer was gutshot and the 2nd was hit too high and very possibly was within 100 yds of last blood. That is common with high hits. They bleed until their blood pressure drops too low and then they still have 5 or 6 good leaps in them.
No bullet on the planet out of a 260 will cure the 1st situation.
The 2nd scenario you could redo a 1000 times and get the deer every time. Spine hits come down to very small differences. .0001 of an inch higher or lower and you may not have posted this.
Seeing things like this many times is why I shoot an Edge at deer. Everyone I know says its ridiculous but guess what? Never lost one. Insurance is cheap. If you are going to shoot deer with a 260 or 25-06 you don't have much insurance. Hit them in the heart/lungs and they will be dead within 200 yds 99.99% of the time, miss by a LITTLE bit and you don't have enough insurance to cover the bet.
