Decided to go for a walk with my son today for a squirel hunt. I relearned a lesson I had taught myself long ago. My son was using his .22lr and I brought a 17 hornet. He had hit 3 squirrels right where he should have and all 3 were drt so to speak. 17 hornet is 3 times what a 22lr is, faster speed, more kinetic energy, heavier projectile.... on and on. I hit 2 squirrels right where I should have and they both were able to make it up a tree before expiring and falling out. So my lesson I learned when I was younger hit me hard again, first deer rifle was a tikka t3 in 30-06, shooting 150 grain factory hornady ammo. I shot a lot of deer with that gun and not 1 of them ever drt. They all managed to leave a nice blood trail, some 30 yards, some made it over 100 yards. This stayed true with heavier ammo as well, went up to 165's then 180's, same results. Did the caliber do the job, yup everytime but was it the best option, not in my eyes. My next gun was a 243, shooting 95 grain hornady factory ammo sst. I never had a deer move after a good hit. That being said if I hit a little farther back then intended I still had a dead deer but it was a lot like the 30-06 results, run and then drop. Next gun was a 7mm08, better results then the 30-06 and the 243 for the most part, just found the 7mm08 is more forgiving if you dont hit exactly where you intended to but as far as the drt is concerned the 243 still takes the cake. So my conclusion is the right round is crucial for the cleanest kill which to me means its over as fast as possible. A round that transfers 100 percent of its energy does not punch through but stays in the animal and if placed correctly has better results imo. Why do most hunters say bigger is better when my field results and studies have proved the exact opposite? Anyone else have some food for thought on this?
