The last chart on this page has some good round ball data.

It sure makes you question the viability of even a .54 caliber PRB at 100 yards with energy of less than 600 ft. lbs.

Yeah I agree that bigger is better in this scenario however, my .45 has brought down a lot of deer. Did have to track them though-but never did lose one. That was my first ML so at that time I didn't have a choice, now that I own others its not the first one I pick out to take deer huntin'(Now it's my fall turkey gun)
Just a side thought, I wonder where the idea of a PRB isn't effective came from? When I first got into ML that was the only thing people used now people speak as if you're better off w/a creek rock. Not that it makes any difference to me just curious...

As ML technology progressed, first with heavy conicals which extended effective range - then with sabbotted jacketed bullets which extended it even more, what is considered "ML range" has increased greatly. So, with current state of affairs being that 150 yards is considered by most to be a perfectly doable ML shot, round balls pale by comparison. Those who hunt with PRB's and know their limitations, know where and how to place the shot, and have the tracking skills necessary, balls are still viable. For the average Joe who shoots a ML a few times before the season to sight in, then hunts, PRB's are not the best choice.

Semisane,For normal deer range [most deer a taken under 50yds] I am not so sure about that I used my long barreled 54 for over 25 years and never lost a deer and in some ways I think its more dependable than inlines because its a sealed system. Lee

Many people maintain that killing power is proportional to the amount of energy "dumped" in the critter, when actually,killing powercomes from the amount of vital organ damage a bullet does. That's why bullet placement is so critical, regardless of the actual kinetic energy carried by a bullet. Therefore, a large, soft-lead round ball only requirtes sufficient velocity on impact to penetrate to, and through, the vital organ(s) in order to kill game regardless of size. Round balls of .54 caliber or larger have been proven to do this reliably, even on game as big and mean as grizzly bears.

Those charts don't explain why when the Longhunter Society came out that the world record grizzly was killed with a .54 Hawken style with 120grs FF goex...
Range was 100 yards, ball was found under the hide on the off side, lung shot...Bear ran 80 yards and piled up....

A well sharpened broadhead at 400 fps had little energy but is an effective killer.

Of course that's only part of the equation. A 200 grain solid steel 30 caliber spitzer at 1900 fps has tons of energy but would not be an effective deer killer. A well sharpened broadhead at 400 fps had little energy but is an effective killer.

I'm not sure where the 800 ft.lbs. came from but I'm sure they were referring to a bullet size or grain weight. Obviously a 450 grain(im guessing) .54 cal. round ball hits pretty hard. Compared to a rifle projectile. If you shoot a 130 grain .270 bullet with 600 ft.lbs. of K.E. it probably won't be a killer like the .54 cal. PRB.

Moebedda, there are a few for instance the new Striker Crossbow.
gleason.chapman, I don't know where you got the idea they the only shot you should take with a PRB is broadside. I have shot diagonally through a big IL doe[ 140 #] and hit the buk behind her in the neck and took a big chunck out of his spine, dropped both deer on the spot. Any 235gr ball bullet or what ever moving at over 2000 FPS is going to do a lot of damage when applied to the right spot.
I bet some of these ideas got started by people trying to use squrril guns on deer and people that dont put half the ball weight or more in powder. Lee

Chap, A .45 muzzleloader shooting a 128 grain PRB has killed hundreds of thousands of whitetails when this country was being settled. .45cal and under. Davy Crocket didnt use no big bore rifle in his days. Back then, those people depended on their rifles for defense and mainly for putting food on their tables.
FPS/ Ft lbs energy mean nothing to me. They are just numbers. I prefer to stick with the history the PRB has made in this country and other countries.

If our fore father's had read this they would have stayed in the old country! Critter's can't be killed there with our gun's!!!
All things have their limitations. Be it a sling shot, ML, CF or bow and arrow. Used within their capabilities all are efficient at what they do.
