Going through a notebook the other day i found a chart showing results of a bullet penetration test. I found it so interesting i wanted to share it with you. Over 15 calibers were used but i can sum it up with showing results of just 4. I am not sure were i got this chart and they also didn't mention the penetration material used. All ammo was standard factory ammo from winchester remington and weatherby.
458 win.mag 24" 510 gr. RNSP 2074 FPS 19.0 inches

460 Wby. Mag 26' 500gr RNSP 2364 17.2 inches

30/06 22" 220 RNSP 2261 17.7 inches
The 30/06 220 grain penetrated more then any other 30/06 load it penetrated more then any 30 caliber magnum load and it penetrated more then the 338 win. mag and 375 H&H with all there bullet weights from 200 to 300 grains.

i also fouind this interesting the 45/70 was tested with two barrel lengths
45/70 22" 405 grain 1322 FPS 15.8 inches
45/70 20" 405 grain 1211 FPS 17.8 inches
The lower velocity penetrated 2" deeper I just wanted to share this info with you guys, i do remember this was a test done to show bullet penetration for calibers to be used on big bears in alaska. I hope someone enjoys the info. Later Tanoose

Were the barnes tsx or x,or the failsafe tested?My own observations have been that these bullets will outpenetrate much heavier bullets of different construction.

No i believe this test was done many years ago well before any of the newer ammunition was available .Mostly used were the round nose soft points and pointed soft points from remington and winchester. some federal also used with weatherby used for the 460.

That is very interesting but I don't find it "that" unusual. Especially when using soft points. If they used solids in the bigger chamberings the results would probably be drastically different. Lower velocities in soft points sometimes yield greater penetration as the bullet doesn't expand as much and holds together better, as least that's what I've seen. I shot two different loads from a .300 RUM into dry phone books at 100 yards. First was a 180 gr. Nosler B-tip at about 3200'/sec. Went through 3 and stoped the bullet was almost totally broke apart. Next was Barnes XLC 180 gr. at about 3200'/sec. Went through all 5 and embedded so far in the tree they were up against it couldn't be recovered.

Thanks for sharing. Any kind of info like that is interesting and thought provoking.

I was once in a sporting goods store in Kelona B.C. and the store owner had a piece of steel plate that he had shot at with several differney cartridges. The only one to go right through was a .220 swift. And so he figured it was probably the best round to hunt with.

"penitration" is one part of the equasion for a good bullet to do a specific "job" on a target.

I believe it was Jack O'Connor that clained his wife's 7 X 57 would penetrate elk deeper than a 7 MM Rem Mag.

From my own shooting I can easily understand this as I've seen slower rounds penetrate deeper than higher velocity rounds.

For those that seem to lust after cartridges like the .378 Weatherby there seems to be an education coming.

Useing good bullets bigger and faster is better, there's your education.

Exactly

Interesting. I realize this is an old chart as you say. However, things have changed. My friend, Norm, whose going bear hunting with me this spring, killed a nice 250 pound bear in Ontario with a 30.06, 220 factory corelokt, at 8 yards. He recovered a perfectly mushroomed bullet in the offside shoulder. Roughly 14-16" of penetration.

I killed a similar bear with my 30.06 and a 180 Swift Scirocco at about 8 yards. Penetration through both shoulders and a gaping hole in the ground, no bullet recovery. And a Scirocco is designed for long range.
