You call that a rifle.

I have forgotten about those movies, they were great! I watched them as a kid over and over.

You and me both. I used to drive my Ma crazy trying to make sounds like Michael Winslow.

That dude was incredible.

So....what's that take for a load? Like a pound of FF for each shot?

 

[LME]

This is a rifle. .490 ball in the muzzle.

Could you take a picture of the whole rifle? I would like to see what size wheels it has! LOL!

 

[Century to late]

That'll knock your fillings out!

I wanted to build a rifled 75 but didn’t know where to get the barrel. A friend special ordered a rifled 69 caliber. Took 6 months to get it.

 

[Frontstuffer070]

Didn't someone post a Brontosaurus killer on here a while back. If I recal it was a rifled barrel with a bore close to 1 inch. like .950" or something like that. I think the fella said the charge was like 200 grains. Aww, heck lets just call up Hern and get us a Mountain howitzer barrel and fit it to a stock.

For the record it is a .75. Why my buddy ordered it in that caliber I don't know.

Gonna need a lot of powder

The 4 bore rifles were the elephant guns in the black powder muzzleloader era. There were some two bore monster guns made too. But the recoil off of these big 2,4,6 bore guns was very abusive to the shooter. I would bet many a shooter hit concussions and injured shoulders firing them. Many were single shot too as they weight a lot. So you have an elephant charging you and you have a single shot and all of your porters fled long before then. Don’t miss.

Seleous with his single shot 4 bore circa 1876.

That's getting on the edge of a crew served weapon!!

 

[Tenring]

There’s no casual woods walk with that plinking targets. LOL…

 

[cynthialee]

You couldn't pay me to shoot that monster.
In my youth, sure I'd have begged to shoot it.
Thing would knock me to the ground

This rifle is a version of a Thomas Simpson rifle which was a real made in Kentucky rifle. Not Pennsylvania. You can read more about the KY rifles in Mel Hankla's book.

Thomas Simpson is famous for building Gasper Mansker's rifle (some will remember Mansker's Station). Frank House is a devote of Simpson's style.

 

[Newly O’Brian]

Sign me up, I'll shoot that bad-boy!

 

[Century to late]

I'm in for sure. At 300 lbs I'll manage. My go to gun is .338 or .58 BP

 

[PaJerry]

It's a big rifle for sure.

Now to show my ignorance. How much more recoil would it have compared to a Brown Bess? 50 cal is the biggest muzzle loader I've fired. Does the rifling add that much more to the recoil? Inquiring minds wants to know.

 

[Relic shooter]

Big bore rifles are much fun to shoot if built right !!

Over 60 some years I used mostly original big bore English & European rifles in competition & hunting.
The barrels on these big bore rifles in the .60-.75 cal. range had deeper rifling of .014-.018 to grip PRB well & usually featured twist of one turn in length of the barrel. The above barrels rarely required more than 80 grains of 2f to obtain match grade accuracy.

The rifling depth on most modern mfg. muzzleloading barrels are cut too shallow in the .008 range to properly grip a PRB so they use a much longer rate of twist & use much higher charges.

My favorite target & hunting rifle for about 4 decades was an original .70 Danish Jaeger that weighed just 7 1/4 lbs, it produced ragged hole @ groups @ 50yds if I did my part.
Additional bonus, didn't need spotting scope to see holes on paper

Go to a local Plumbers store they have pipes of all sizes! LOL!

Thicker patch and even thicker shoulder!

 

[Rawhide67]

Might as well try a buckshot load of 50cal round balls. Just for sh** and giggles.
