Idaho F&G did the same test in 1991 with 50 cal PRB,50 cal great plains conicals, and many others.
The 50 cal PRB into test clay. it had 7 1/2" of penetration.
The 50 cal Hornady 385 gr great plains had 12" of penetration.
The test went on to say " Round ball performance in all calibers tested were NOT impressive. At the 50 yard test distance they flattened out excessively which restricted penetration."
It also says for the Hornady Great plains bullet that the expansion was uniform but excessive.They didn't recommend the 50 cal 385 for elk. They recommended the "new" 410 gr great plains bullet.
The Buffalo bullets in all calibers and configurations were less likely to give uniform performance but delivered deeper penetration over all that the others tested. The only draw back to the Buffalo bullets was they were rejected due to poor accuracy.
Thompson center MaxiBalls were said to have a reputation for excellent penetration, poor expansion, and good accuracy. Test results were consistent.
TC Maxi Hunter- "Tests suggest that expansion enhancement may have been overdone a bit. Performance was similar to the Buffalo bullets, but less convenient to use since they are not pre- lubed".
The test goes on to tell about sabots and pistol bullets so I won't go on with that. It also tells about animals killed with a lot of the bullets mostly elk.
What it does say is NONE of the projectiles were "magic". I didn't read anything about the Phantom killing ability's of the PRB. They do give FPE stats, and speed. They said the PRB's work but use 50 for deer minimum and 54 for elk minimum. They also said that shooters shooting the PRB "mostly wring out superb accuracy from them and through precision shot placement and above -average hunting skills can partially overcome some performance deficiencies posed by round ball use."
In short the PRB is for top notch expert hunters only.
This test was performed by Al Marion of Boise Idaho and Gene Autry of Star Idaho. The full text can also be found in the Summer 1991 Issue of Black Powder hunting magizine. Also this was fully covered by the "Idaho Hunter's Guide to Muzzleloader Performance and Limitations"
These guys were not "gun writers" they were black powder hunters and shooters. They had no dog in the fight or sponsors to appease. I have seen first hand how PRB's have failed. I don't care for them but I don't care if anyone else wants to use them. I don't go on to PRB threads to try to make converts. I have my ways and others have theirs.

I tell myself, stop posting its pointless.
But then...
What clay did they use? Did they test each block before firing to assure they were all uniform. Most people who shoot gelatine for serious testing use a low velocity air gun to give a penetration check before shooting the real gun to assure the block is uniform too much or too little penetration and the block will give inaccurate results in the real test.
So what bullet/cartridge/load did they use for a control? And how did they determine it was to be the standard for penetration? Did they then correlate penetration in the clay to penetration in an animal?
Gotta have something to compare to after all or the testing is MEANINGLESS. I could use this.
Shot on the same day with the same 50 cal that broke the deer's shoudler to indicate that approx .150" divot in this steel plate at 30 yards or so means that a 50 RB will shoot through a deer side to side at 60. Its meaningless just the same since:
If I had a 300 Weatherby and some 1980s 180 gr factory ammo I could probably "prove" that while it would not shoot through an elk it WOULD shoot through this piece of steel. What would it REALLY prove?
It would prove that the rifle would or would not shoot through the steel target.
I do know that a 54 caliber percussion Sharps "Christmas Tree" bullet backed by 70 grains of BP from a saddle ring CARBINE will shoot through a mule deer from end to end breaking a large leg bone in the process. But its pointed.
I have a sneaky feeling that unless hollow pointed and loaded heavy many ML bullets will do the same. I bet the Sharps would not make over 12" in clay either.
Did they test any 7 mag with 140 gr in this medium?
Or maybe a 264 mag with a 140 grain which at 40 yards failed to get through the shoulder muscles of a bull elk at 40 yards TWICE.
I have seen a 300 Weatherby Mag factory 180 grain shot into an elk I caped stop in about 5" on a 40 yard shot. The only thing the "saved the day" for both these magnums was that the 264 got the neck on the 3rd shot (the neck is closer to the hide than the vitals behind the shoulder muscles) and the other from the 300 hit in the withers and stuck a projection off the spine, where it stopped. But a previous shot had cut the elks throat and he then bled to death. The withers wound had no visible bullet fragments except the jacket base.
Note that the 54 RB which broke a large, heavy bone in a big old cow continued on to kill the elk. I would recommend a caliber larger than 54 for most hunters shooting elk but it has a good track record none the less.
In any case the 54 RB produced more penetration than either the 264 or the 300 exhibited IN THESE CASES.
In fact a 54 pistol I killed a Mule deer doe with, breaking the upper leg bone going in, penetrated farther than either of the magnums mentioned above.
Makes me wonder how far the 300 WM factory 180 would go in "test clay" at 40 yards. 12" maybe? Heh heh!
I have never seen any RB fail to penetrate to the far side at least on broad side chest shots. Never shot a buffalo though so don't know about that.
So when I see something like this that is so far removed from practical experience I really have no answer for it other than to simply chuckle.
How could anyone who claims to be a ML hunter take 7" penetration with a 50 caliber RB as anything believable? Unless they were out to prove the RB would not penetrate and had never actually hunted with them.
The last deer I shot with a 50 using 90 gr of FFF Swiss as previously detailed penetrated more than 7" AFTER breaking the shoulder blade right at the socket. How am I supposed to consider the testing you describe as valid. Where is the correlation? How do I reconcile this? Do I believe the clay test or do I believe what I have repeatedly seen in actual use over the years?
So the question for the people here who have ACTUALLY SHOT animals larger than a fox with patched RB is:
Have you even had a rb penetrate only 7" in a deer or a bear or an elk?
Traditional bullets? Find me a citation for a ML bullet other than the picket in anything like common civilian use in America prior to 1880.
Read Chapman's book "Instructions to Young Marksmen Improved American Rifle" printed in 1848. It has no mention of them even though it concerns itself with bullets and not balls.
But he does point out that without at least a guide starter
pickets will invariably be erratic.
My testing has shown this to be the case no matter what tricks I used so I made the the starter pictured. It fits OVER the turned muzzle and the "piston" is perfectly aligned with the bore. Centering the patch on the muzzle, then pressing the bullet into the recess in the starter reamed to a slight press fit for the bullet then putting the starter on the barrel and pushing the bullet into the muzzle and decent accuracy will be obtained 4" or so at 100 yards. If you whack it with your hand accuracy fails.
This rifle is a 48" twist 40 cal and I use a picket that weighs 160 or 135 grains depending on how long I cut the lead wire.
So if any of you think that the REAL, MAXI, MAXI-HUNTER or any of the other various and sundry modern ML bullets are "traditional" you are simply wishing it so.
SHOW ME THE PROOF. There is no historical proof that I know of at least not until the cartridge era and then it was target shooters in the east.
The picket was widely used in target shooting, usually 40 rods (220 yards). At this distance it would out perform the RB. But in the picket matches held at Cody the picket bullets do not shoot as well as the round ball at 100 yards.
I should have had a 100 yard shot in competition picket target to photograph but I had a Murphy's Law smack down after loading the rifle for the first sighter and did not compete at the only picket match I get to once a year :cursing:
I kinda lost interest in this and don't really practice with it. Just shoot it at Cody for fun, if it does not break.
This runs a little long but I do so the show that I actually have shot some elongated bullets in MLs and even shot a deer and a bear with the Italian copy of the Percussion Sharps. But the 54 RB rifle is a far better hunting gun. Longer point blank range and no difference in killing power. I have not shot anything with the picket rifle. If I carry the starter around in the field and ding the piston mouth it will require making a new one and turning it to match the starter and the cutting a cavity to match the bullet nose. Its a lot of work and one dent and the piston is only good as a punch for installing sights.
Probably why we don't see a lot of late plains rifles turned for starters...
Not to mention its heavy and the bullets are heavier than RBs and for hunting offer only increased range as an advantage and several disadvantages. And in shooting at unknown ranges a sighter will invariably be needed as is almost always was at longer ranges with the Sharps and other "long range" single shots of the post Civil War west. Sighter shots with a ML take a lot of time...
There is no magic bullet.
Everyone likes to deride the RB but invariably they have something to sell, have been bought or have never used one on game.
The only failures I have ever seen in penetration were HV jacketed bullets that were simply not able to cope with the impact velocity, especially when sticking bone or heavy muscle.
In this case they fail Forsthe's "adequate" test.
When they work they work wonderfully but when they fail they fail in a spectacular manner. Lead bullets unless hollow pointed excessively, be they fired from a cartridge gun at BP velocities or from a ML. Round or elongated do not fail to penetrate adequately.
If used in too slow a twist an elongated bullet is known to not track straight, this has been reported by people I know who once hunted with the MAxi-ball and by surgeons in the 1850s-60s military who found that the minie would sometimes turn 90 degrees on striking a man and might enter his chest then turn and exit at the hip.
People I trust used the Maxi back in the 1970s and finally gave it up as a bad job on Moose, where the Maxi should have acceled and went to larger diameter RBs of similar weight and found they killed much better and would track straight.
I have never had a round ball deflect until it had penetrated past the vitals and then only twice and one only after about 24" of penetration inches past the vitals its destroyed and then not wildly. I HAVE had some modern "gee whiz" 45-70 factory loads deviate wildly from their intended course after 1" or so of penetration due to the design of the bullet even though significantly over twisted. Its not a good thing as my friends also related from their experience with the Maxi in 48" twists.
Other than the Maxi which I have heard and read several reports of pretty strange occurances with this bullet.
I would not malign the killing power of the conical. I have killed too much game with BPCR using similar bullets.
My disagreement is in the supposed vast superiority of the conical. If the criteria is narrowed to certain situtations, like shooting almost completely through a large Bull Bison at a 45 degree angel as I have done with a 45-100-500 then the RB might be deficient. But in "normal" use at the ranges game is shot with traditional BP arms they really is no difference in effectiveness. But to modern shooter the bullet is more familiar and LOOKS better to them. So somehow it has to be better.
In reality with careful examination of wounds and enough game shot the difference is simply insignificant and can be attributed to the individual animals hardiness. Some simply do not know to fall over. I have shot WT does at short range through and through just under the front of the shoulder blades. This deer was already "amped" as WTs often are and even with what can only be called a heavy hit (100 gr of FFF 535 rb at about 30 yards) she ran 200 yards across the hay field and died mid-leap sliding to a stop on the snow. In that 200 yard (long steps)run her feet only touched the ground 10 times. She died in seconds but made a lot of ground.
I have seen some similar runs from deer shot with modern medium magnums. Next one will pile up when shot.
So if the "runner" and a similar happening with a 50 on a MD doe years previous were the only experience the rifle would be deemed inadequate. But seeing the results of deer shot with moderns that are without question if anything over powered for deer and the distance they sometimes cover it then comes into perspective.
As I previously stated I have shot or seen shot 100s of deer, antelope and Elk and a couple of bears. With a well placed shot they usually make 40 yards. Some much less some a lot more.
The round ball has been maligned in press since the advent of the modern ML bullet. Prior to that there was no problem. But when the bullets arrived and needed advertising it became useless. It was no better or worse after the maxi came out but the ADVERTISING and hype needed to sell the "new and improved" required it be deficient otherwise people might not buy the new bullet.
It really comes down to this.
I don't like having my intelligence insulted.
Now its well past bed time again...
