Yes, lack of heart pumping contributed to the lack of blood trail. But the lack of an exit wound also heavily contributed to it. I've blown hearts out on deer before with other rifles and still get some level of blood trail.
I also did hear the direction he ran but I don't believe he crashed. The ground was not kicked up where he was laying and he was on his belly with rear legs tucked under him. Also he was facing his back track.
Like I said, I was within a few yards of him a couple times. His direction of travel was within 10 yards of what I marked on GPS immediately after the shot.
Furthermore if you talk to any dog tracker they will tell you that grid searching is the best way to push a gut shot deer and render them unfindable. Without much hit evidence, it's hard to know what kind of hit you're dealing with. The mule kick and the fact that this deer's back half was covered at the shot were the only reasons I gridded at all.
Again, I'm not attacking the tmks. Just giving another data point.
The best time to decide whether or not you're tracking with a dog is prior to ever going near shot site or trailing a deer. You're right about this.
Grid pattern is vegetation and terrain specific. If you walked past the deer, your grid pattern is too big.
Most of the deer I shoot are in or near thicket or CRP. If I don't hear the deer crash, or see it die, and I don't know with a high degree of certainty where I impacted the deer, and a dog tracker is available, I'm calling them before I look. If they're not available, shot circumstances dictate when to start looking. And if tracking turns into grid searching, the grid pattern size can't exceed the ability to see your last pass or step on the animal. Otherwise, grid searching is pointless, and worse - like you said - will make things harder on a dog.
Before I spent time actually thinking about how the grid search should be executed, I ended up walking past some deer. Since deciding to really do it right, if the deer is inside the search area, it's found.
It is totally unrelated to bullets, and their terminal performance. But if a grid search is executed correctly, it should be 100% successful. Given the spirit of this thread, a grid search failure is one that ends with a deer being inside the grid search area, that doesn't have eyes laid on it prior to search ending.
If you walked past a deer multiple times grid searching, that is a failure.
Edit - this isn't a personal attack. You are not a failure. The grid search was. Welcome to Costco, I love you.
