65: Thanks for posting.I have the entire work saved somewhere in my computer,but had not read it in awhile.

General items that jump out are how good bullets like the Barnes X,Swift Aframe,TBBC,North Fork,really are by objective analysis;and how well the 60+ year old design of the Nosler Partition still hangs right in there with them all,across the spectrum of calibers and impact velocities.A lot of this gets borne out in real life.

None of this should come as any surprise.There are a couple of anomolies that jump out....one was the amount of penetration frequently given by the Swift Aframe,despite its substantial frontal area,frequently hanging close to the Barnes X.Another was the increased penetration of the 140 NF as velocity increased;noted by the author.

Pretty obvious these (Barnes X,Aframe,Nosler Partition, TBBC,North Fork)are among the very best designs for BG hunting,clearly demonstrating their superiority in a number of categories.

I love the stuff about the heavy flat point handgun bullets penetrating deeper than anything else.

Interesting read;always worth reviewing.

I've had that page bookmarked for quite a while and refer to it occasionally. I find terminal ballistics fascinating and have done my own wet newsprint testing for years. My little experiments have pretty much confirmed what is reported here. Bullet construction -- the Partition aside -- has changed so much in the past 10 years that its worthwhile to study whats available because the new bullets do open up many possibilities. It's not that older styles are not worthwhile, it is more that newer styles add flexibility to calibers and cartridges.

I didn't read the entire article but there was some interesting findings in what i've read.Got to bookmark it.
But how does this type of testing actually compare to the reality of shooting game?

gravestone I think it correlates pretty well, in general.

Of course I'm only speaking from the standpoint of having used a relatively few designs extensively enough to get a realistic handle;that is meant to say that unless you are doing a lot of cull work on various sizes of game(not just deer),it's hard to get a broad range of experiences with relatively few animals.

North American bag limits don't give a guy a chance to shoot enough animals to really get a grip on a wide variety of designs....and since many here have a "dead is dead" approach, it might look like lots of bullets "work".

Like mtrancher says above,I think the results correlate pretty clearly to what I have seen from things like the Nosler Partition, and the bonded bullets based on my own use of the Bitterroot (similar to TBBC,NF, and Swift Aframe);enough to convince me they stand head and shoulders over C&C designs across the board.

Gravestone, it simply provides a baseline. Hunters tend to be very loyal to what has worked for them and will defend what they have had success with. Nothing wrong with that. Even with whitetail deer, the most common big game animal, the few inches of difference between a meaty shoulder and a good rib shot can make quite a difference with some bullets so the onus is always on shot placement. In most cases common sense and avoiding extremes are sufficient. When you compare a true match bullet and/or a true varmint bullet against a monolithic, for example, it is easy to see why one might move more into the center for all-around performance. Or, if one is counting pennies, a comparison between two less expensive bullets might tip the balance a certain way. Mostly, terminal ballistic testing is simply fun. (Messy with newsprint, but fun.) With bullets like Northforks and the Barnes MRX it can be quite a challenge to have enough newsprint to stop the bullet. M.L. McPherson was of the belief that saturated phone books were better than gelatin to replicate big game results.

I see several controversies brewin', among them:

1) Keith-style bullets' shoulders not being responsible for wound channel diameter.

2) Observations on calibers smaller than .257 (.224, and .244 guys are gunna be goin' apechit).

I'm sure there are others, but in my initial reading - those are the two that popped out at me.

First sentence, "There aren't many predictive methods calibrated to actual field results or to controlled tests."

You can use theory and perform a lab test in an effort to simulate shooting game, but the only true validation is the actual results from actually shooting game over a period of time. It doesn't exist, but even if we could invent the perfect lab model, the perfect theory, the perfect controlled tests, and the perfect method to predict results.....the proof would not be in the lab results, but the proof would be in the results from the field model when you actually shoot game.

Take results of lab model tests as a way to compare particular characteristics under particular sets of circumstances. Such comparison in a lab model may or may not relate to desired effects when observing results from use in the field.

This is one thing that popped out at me also. There's a fair amount of guys on the fire that have both deer and elk with .243 & .25 calibers.Then there's others that say they've had good results withh 223's on deer.

I don't think he said that 24's and 25's wouldn't kill deer and elk, nor that 223 cal's would not kill deer.Rather he seemed to imply that for both jobs there were better options.

After my 2000 season experience using the .243 Winchester I don't feel terribly confident in this caliber for big game either

No mako i'm not looking to go down that road.I appreciate a man putting in that kind of time and sharing with everyone.By no means am i a ballistian. In my limited experience with the 243 it seems to a very adequate cartridge for deer,at least for me.

The ire won't be directed towards you for simply pointing out what the study says (well, it shouldn't anyway).

I have zero hesitation in using a .244, and while I don't prefer the .22's - I've seen the results, and it's dead critters. Many times, LARGE ones.

What I see as valuable in newsprint testing is to determine for yourself if the bullet performs as the manufacturer describes. There will always be those claiming the exception rather than pointing out the rule, but, if you test enough bullets from a variety of calibers at varying velocities you do get an idea if the bullet is performing in accordance with its design and marketing. And, of course, the medium has to be consistent. The best cup and core bullet is likely to disintegrate if the newsprint is too dry, but even then, if the medium is consistent, you can determine which penetrated more before shattering. I've drawn my own conclusions, of course, from my own testing but I'm hesitate to mention them due to the flammability of the electronic media.

This is true, the wound channel is determined by the size of the me-plat on the bullet. I have shot enough game with these bullets to have observed this in the field as well as in test media

Posted link for 'informative value' smile

Re: the author's statement, sort of 'premature' to base his assessment of the 243 on a few kills w/random bullets. Have to know more info to conclude anything on those WW powerpoints. Suffice to say, I have had GREAT results using 95BTs and 85 TSX, as well as others. The 100 PT may not make the widest wound channel, but it will give 2 holes, my first deer kill was using it, but I wanted something more, and think I have found it.

Alot of good info in the article/review. I can say, just like in medicine, the OUTCOMES Data (what happens in field) may be far more important than stats/pics of bullets.

Use what works for YOU. Often certain bullets have 'trends,' and I find myself going w/those that are most favorable - in their actual shooting/hunting - those results showing up from many sources.

Most often, a bullets reputation over a LONG time will be seen by it's results. IF the cost of ALL bullets were equal, I'd fathom the majority of hunters would choose a premium of one kind or another.

Doubletap would you please explain this further. I guess you're talking about Elmer Keith and the cartridges and heavier bullets he liked to shoot?But what does makos quote mean?

I believe this is the idea: Consider two .430" diameter cast bullets, one is a Keith with a .270" meplat and .430" shoulder, the other is an LBT flat point round nose with a .340" meplat. Despite the lack of a full diameter shoulder, the LBT hits harder and makes a bigger hole.

The second bullet makes a bigger hole than the first:
