I have used many bullets over the years (Berger's, Barnes, Nosler ballistic tips and accubonds, partitions and now hammer bullets). I just like trying different things. I also have two different Sherman rifles not because they are better but because it was fun to do.
I haven't killed as many animals as some on here (in the 100's). But between me, my son and some buddies that I have taken hunting and used my rifle, I have been a part of 15 elk, 8 coues deer, 6 mule deer, 3 buffalo, a lot of whitetail deer (in Texas you could kill 2 bucks and 3 does) and a lot of pigs and a crap ton of coyotes. All of these animals were BEHIND the shoulder point of aim shots and the only ones that have gotten away without me finding them are coyotes and that is because they were on the run and I made a bad shot on it.
All of the big game mentioned were all recovered within 100-150 yards of where they were shot. Oddly enough, white tail deer were the ones that ran the furtherest after the shot. And all of this was while using all of these different billets except the hammer hunters as they are new to me.
I say all of this not to brag but to ask...how does one know where they hit an animal if they didn't recover it? I hear a lot of people say.."the animal got away and I hit it right behind the shoulder, I will never use such and such bullet again!" Even if you have a spotter, they can mess up and miss call your shot. I saw a guy shoot an elk and the spotter said he hit it right behind the shoulder and dropped it. Well the elk was still moving on the ground. We got up to it and he hit the elk in the spine a little far back and that's why it dropped. He still recovered the animal but it was a bad shot that would have been thought of as a good shot had he not recovered the animal.
Do bullets sometimes not perform as they should? Yup...seen that happen too. 180 Gr Berger out of a 30-06 on a mule deer at close range. Literally blew up on the shoulder and never went through to the vitals. The deer ran off and they almost didn't find it but when they did find it, it was laying down and very much alive. How do we know all of these details? Because the animal was recovered. I think a lot (not all) of these bullet arguments where the animal got away even though it was hit right behind the shoulder into the vitals is really a bunch of made up hoopla that the hunter wants to believe besides making a bad shot and I'm taking about any bullet used. Picture of deer below.
I get that people become huge fans of bullets and rifles because that is their experience. I don't agree with them getting in and bashing others for not using them or saying that they didn't work out for them. I'm also not a huge fan of someone bashing people for using said bullet or rifle and calling them fan boys. People should just mind their own business on both sides and use what works for them.
