Whilst working up loads for my Mountain Mold 405gr hardcast pills, my #1 son commented "Probably not enough left at 100yds to harvest a medium boar."

I couldn't argue his point, 'cause I don't know. Looking for someones' results in testing 100yd terminal ballistics as it relates to their harvested game.

I can look at penetration thru 4" of wet phone books [harder to find now] but cannot relate that to harvested game, as I never hunted with my 'home rolled' yet. Planning on bringing something to central Florida next Spring for possible hog hunt. I'd like to have some idea what it might do for me. Thanks pards.

I don't know anything about wild boars, but 405gr of lead is going to kill all but the largest game on earth with ease. What load have you come up with?

Energy and Velocity numbers are good ways to compare cartridges and trajectory which is black and white science (trajectory), but not so much when it comes to killing power. muzzleloaders, 30-30, 35 rem, 45/70 have pathetic energy and trajectory numbers compared to 300 wsm, 7mm 30-06 that are common, but they kill just as well and ruin much less meat.

Well, I can tell you that with my 405gr hard cast at 100 yds it'll whistle right through an elk and out into the woods somewhere. I only recovered one boolit and it traveled the length of the elk hitting the big leg bone and stopping just under the hide. These are traveling at around 1650fps. Trust me when I say the boars you are hunting will not stand a chance of deflecting this bullet and walking away.

Walstr.

Without a cartridge specified, can only make guesses when attempting to answer your question.

I can say, as I have been there and done that, that a 465gr Wide Flat Nose cast put out the muzzle of my 45/70 at 1650fps has enough terminal energy to put big cow elk on the ground in less time then it would take me to tell about it. Been there and done that a couple of times.

On top of that on a quartering shot which took out the big front shoulder/leg bone then a rib which caused the bullet to take a real beating, the bullets still had enough energy to travel over 2 straight line feet through lungs, a big and full and heavy paunch, guts and almost exit just ahead of the off side rear ham.

This bullet has about 2810ft. lbs. of muzzle energy according to a formula seen on one of the forums this morning.

Using the same formula, my RUGER 77/44 rifle will have about 1764ft. lbs. of energy with a 275gr cast WFN and a muzzle velocity of 1700fps.

There is little question that this 275gr cast with it's large meplat will be an effective deer thumper at 100yds.

Your 405gr should get er done without question. Just use a bullet with the BIG meplat, a good alloy and a velocity in the range of 1400 - 1700fps and you'll be good to go for hogs.

By the way, pay little to no attention to the term, "hard cast" unless that claim comes with tested hardness figures.

My 465gr - 45/70 bullet is cast of 50/50 alloy - Wheel Weights/lead and water quenched as they fall from the mold. Doubt it is really hard, but it IS AWESOME on deer and elk! In any cast they would not be as hard as Quenched WW, but they flat get er done!

A common standard required for boar hunting in many European countries is 1000J of kinetic energy at 100 metres.

A Joule is 1.355818 ft.-lbs., so you are looking at 1356 ft.-lbs. at 110 yards, approximately. You want 1450 fps average on your 405-grain bullet to ensure that no individual round drops below 1430 fps MV, which would only barely make your 1000J at 100 metres.

Don't be misled by the ft-lbs alone at 100 yards. According to the chart above, a 405gr starting at 1450 ft/sec will be down to 1243 at 110 yds. If your son is used to higher velocity rifles, say, 30-06 or 7mm mag, this figure will look low to him.

What the chart above doesn't show is the penetration. The 30-06 will be pushing 165 or 180 grain bullets, the 7mm will be pushing 150 or 175 grain bullets. The 45-70 is pushing 405 grains. While the lighter bullets will expanding rapidly and just as quickly decelerating, the 405gr will still be chugging along, all the way though your target and ready to penetrate another one, or two.

The difference here is between the wound cavity created by the smaller rounds, vs drilling a 1/2" hole straight through your game animal and still going. It will do this at any presentation angle, giving two perforation holes. Remember, it was the 45/70 with 405gr bullets at 1450 fps (muzzle velocity with black powder) that very nearly exterminated the American Buffalo. Against a feral hog, the 45-70 will do everything you ask of it. It has acquitted itself very well against African game.

Walster, Mike Venturino has written that a .45-70 405gr bullet will exit a big Bison Bull broadside from a black powder rifle that gives 1300 to 1400fps. He said more velocity only throws up a bigger divot on the far side of the Bison.
I think your load will take hogs day in & day out. I wouldn't worry about it.
Good shooting.

+1. Heck, a .22LR will kill a pig at 100 yards if you hit it in the right place. The .45-70? It's made for big game like bison. A pig doesn't stand a chance.

Keeping it simple. Good question but its one of those a bit worried for no reason sort of questions. Its a 405g bullet. I have started many of them down the barrel at 900 fps (chronographed starting speed) with great accuracy and minimal recoil....each and every one of which broke both shoulders of deer at 75 to 120ish yards and left em DRT (Dead Right There). You'll get similar performance from the same large slow bullet on deer, mule deer, bore, javilina, goats, rams, etc and ad infinitum. Find a load that shoots good for you with that 405g bullet and show your Son that his paper ballistics don't come close to accurately describing field performance when you put the pill in the proper spot.

Yes Frank!!!!!!!!!

Every deer I have shot with the 45/70 - 465gr Wide Flat Nose at a muzzle velocity of 1650fps has been a bang flop. Everyone, except one that I hit back just a couple inches back from my normal lung shot. That one ran maybe 50 yds. or so. Dead on it's feet, but not dead where it stood as expected.

You know, it is funny how our mind works, :shot: :vollkommenauf: :flute: but almost immediately the thought went through my mind, I need something bigger. Ya right, NOT!!!!!!!!!!

Didn't take long to put that thought where it belonged, in the trash, but there it was.

As you said, "shot placement."

Three of the four in this link dropped NO PROB. I think we were all using Remington CoreLok 405gn SPs. Nothing special. All were DRT or Dead Right Over There. Seriously, don't worry. That was why you got the rifle, correct?! Because it will drop large game. Boar aren't large in the Large Game sense. Lots of fun and man are they good eating but unless you run in to and/or paid to hunt hogzilla, they aren't that big.

The proof is already in the pudding. Or maybe someone should have told the American Bison about terminal ballistics.......

I think I would make a deal with my son, if it kills them he cleans them. If not you clean all his hogs. You will be able to sit back with a cold one supervise the cleaning operation.
THIS! This is genius!!

But seriously... energy figures are retarded. They are HEAVILY skewed to favor velocity over weight, but bullet performance is all about momentum. Performance wise, there is precious little difference between a 200 grain bullet moving 3000 fps, and a 400 grain bullet moving 1500 fps, except that the heavier bullet will generally penetrate further and damage less meat.

Your 45-70 will kill anything in North America even with Hornady's LeveRevolution 325 grain bullet.
