Interesting question

I seen this question asked on anuther website, and I'm not sure how to answer it. Anybuddy have an answer thet is based on the ballistic performance of blackpowder??

TIA for any information,

Is 3000 FPS possible with a BP muzzleloader?
Is it possible to achieve that velocity or higher, with a blackpowder muzzleloader?

If a powder chamber were enlarged to some specified volume and a projectile were placed exactly at the throat of the powder chamber in a configuration that looks like one of the short magnum rifle cartridges, and the barrel was thickened and lengthened, might it be possible?

What you would see in profile is an expanded powder chamber shaped similar to that of a rifle cartridge, or the best shape engineered to get the job done. The chamber would be filled up into the rifling and the projectile seated on top. Engineer the thickness of the barrel and the necessary barrel length.

Or....is there a maximum attainable projectile velocity that is determined by the burning rate of blackpowder?

Cost , recoil and weight are not a consideration here.

Well you can get High Velocity with Black Powder. A 16" Naval gun can fire a 2100lb projectile at 2750 Fps with 677lbs of powder, and the King of High Velocity with Black Powder should be the Paris Gun it fired a 234lb projectile with 440 lbs of powder and reached a muzzle velocity of 5250fps. Now that we know BP can reach that speed who is going to make a muzzleloader that can reach it? P.S. it should be a flinter let's not let the inline guys have the record LOL

I believe it can be done in a shoulder-fired arm, but don't think a radical bottleneck chamber profile would be best. The reason I say this is BP cartridges are almost universally straight-walled or have only a slight, gentle bottleneck. For some reason, severely choked-down profiles are less efficient and really inacurate. An example would be the Martini/Henry. I bet a muzzleloader in 40 cal that was proofed for 180 grains of 3F firing a (I know you don't want to hear it) saboted 32 cal. ball would come close, though.

Thanks fellas,.... I "relayed" what you both said to the fella ask'n the question. :thumbsup: :redthumb:

I was checking a web-site (Midsouth Shooters Supply, maybe.), the add for savages smokeless powder inline said it is the only .50 caliber "ML" that can reach velocities over 2300 fps.

If that's true, I take that to mean that a real BP gun won't do it.

I was searching for some crossbow information today (another of my interests) and I found a hunting forum where some guys had been bickering about using crossbows for hunting. During the argument, one guy made this point about inline muzzleloaders:

As for inline muzzel loaders, I recently watched a show where a guy chronographed a ML at over 3000 FPS shooting 4 pyrodex pellets and 180 gr saboted rifle bullets. It was acurate out to 5oo yards.

He didn't say what show he was referring to or give any other details, so don't ask. But I thought it was interesting in light of the discussion going on here. Personally, I'd need to see it to believe something like that. Like they say... If it sounds too good to be true, it probably is.

Wonder how "Accurate" is defined in this case?

Beats me. But he said they were "saboted 180-grain rifle bullets". That description, along with the claim of shooting at 500 yards, would suggest that he was using something like a spitzer boat-tail .308 bullet in a sabot. I'm no authority on inlines, but as far as I know, there are no muzzleloaders on the market with a twist rate fast enough to stabilize a 180-grain modern rifle bullet at 500 yards.

If there are, then I want one of those barrels for my flintlock! ::

 

.32 cal. 1 7/8 across the flats with 280gr FFF Swiss. Talk about a new SSM (super short mag)....... :crackup: :crackup: :crackup: :crackup:

For get it it's not TRADITIONAL! :blah:

But I'm sure flint would touch it off eace:
