.223 for bear, mountain goat, deer, elk, and moose.
All the kinetic energy calculation does is make an effort to describe power. Power is not directly correlated with killing. Two bullets of different construction, say a FMJ and a Nosler Partiton can have the same level of energy yet their killing ability will hinge on shot placement. With head... -

But energy is how we measure the destruction velocity and mass can create. Bullet construction is the method we use to disperse energy. Energy as calculated is not a perfect measure but it is what we use. -

Same here. Years ago an author named John Lachuk (spelling?) did a good bit of experimenting using plaster of paris and modeling clay. He must have been a very patient guy but his testing seemed to bear this out. It was hard to get exact results but he came pretty close. -

Ok say we have two different 77 grain bullets pushed to the same velocity. One that penetrates deeply and one that makes a shallower but wider disruption of material. If we had a media such as modeling clay that doesn't collapse upon itself and filled the voids caused by the two bullets with a... -

It is obvious that being a professor is beyond your reach. We are simply discussing velocity, energy and mass's relation to tissue disruption and since we are talking about a cartridge on the lower level of the energy spectrum speculation on it is relevant. I do use 22 centerfires for hunting, I... -

Agreed with the exception that the volume displaced by two different bullets with the exact same energy level and mass will be the same, the shape and depth of that volume are what can be different. -

So if terminal energy doesn't matter why aren't we shooting 17 grain bullets at everything? It is hard to argue against the effectiveness of larger cartridges also. Who is saying terminal energy does not matter? The application of energy is what matters. If the energy destroys heart and lung... -

I have never wounded and lost a game animal. In my youth I did make a few misses. I have had poor bullet performance cause some tracking and difficult retrieval. When shooting at steel or distant rocks I often use the impact of a miss to adjust my aim. I don't shoot at game animals unless I... -

There seems to be some misunderstanding of the energy calculation and it's value. The application of energy is what counts. I feel calculated energy is more of a method to measure destructive power volume. Meaning if you were able to measure the volume of a wound channel with differing levels of... -

Back before there were many .224 rifles with twists faster than 1-12 I used the two 60 grain Hornady bullets available then, a HP and a sp both flat based on deer with pretty good results. I also used the 70 Speer. These bullets did not have high ballistic coefficients so I kept my shots under... -

No the point you are missing is that a skilled shooter can put the first round from any rifle he is familiar with exactly where he wants it. I can. Training with heavier recoiling rifles to get to that point does take longer. When I pull the trigger shooting at an elk I am not thinking about the... -

A 338 Lapua can be quite comfortable to shoot if it is heavy enough and has a good break. However very few people use one. In my case I can put bullets exactly where I want them from any position with my current most powerful rifle, a 35 Whelen. Second being a 7MM RM. I generally don't notice... -

So not having years of experience shooting rifles from 338 WM down to rimfires. His article was subjective and he was the subject. -

Not at all unless you are talking about long strings. It very much matters how good a shooter you are. Hunting usually means one and done unless shooting prairie dogs and the average prairie dog rifle isn't much of a kicker, after all they weight less than 3 pounds. Do I enjoy how my 7MM RM... -

More powerful rifles do require more practice to shoot well. Was there any mention of how much shooting each of the participants did? My Model 7 in 7-08 is harder to shoot well than a varmint weight barreled 223 without question. It won't shoot half inch groups no matter who is behind the trigger. -

What I meant by "better" and I used the word might, is straight line penetration "might' be better if spun faster. I posted some pictures of a deer hit with a 75 gr. Hornady HPBT shot from a 1-9 twist barrel that 2 out of three shots wildly diverged from sight line. That bullet is shorter than... -

The 73 gr. ELDM out of a 1-9 twist is on the edge. That bullet is designed to be run in AR15's but maybe you will have good luck with it. 1-8 or faster would be better. -

What are the best impact velocities for the TMK and ELDM bullets? I know there is expansion down to 1800 fps but It would seem a little more speed would be better. I see a lot of people shooting 16 inch barrels and from a 223 with a 77 grain bullet I don't believe many are going to see 2700 fps... -

I'm putting together a 16 inch barreled upper in 22 ARC , when my upper receiver finally gets here. Seems I may get close to 2600 fps with it if your getting 2670 fps. I was guessing 2550 fps. Will chrony when I get it together. Bought three boxes of the 88's for brass but may shoot something... -

Ok then just loaded up some 73 gr. ELD for my AR, 20 inch barrel. 2820 fps. Next few animals I shoot at will receive one of them.
