Flintlock Pistol Muzzle Velocity

I'm thinking of making a summer project (this summer) of building a 50 caliber flintlock pistol. Because they are legal for Pa. hunting and they are just neat.

However, OTOH I don't see 'em has much use if they can't get to the vital's of a whitetail at 50 yards.

I'm not impressed with the Traditions kit guns, so I'm looking more at building one with quality parts that I will choose. A Siler or L&R lock and a Green Mountain Barrel will be the shooting part. So, I'm thinking I should be able to use a FF powder charge of at least 60 or 70 grains under a 240 gr. conical.

But again, I'm just guessing.

I currently shoot a Green Mt. 50 cal. barrel with a 90 grain charge of FF under a 240 lead conical. This will easily drop a whitetail at 100 yards....but the barrel is...Ghee, I don't recall....maybe 32" or so long.

However, I can't seem to Google up a chart that gives me the powder charge and MV of a 50 caliber flint pistol. And I don't want to build one only to find out it will kill a whitetail....out to 10 yards.

So....does anyone know what the MV of a good muzzle-pipe pistol be? And the powder charge of the same?

Thanks

Dave

Dave, I am with you. I want a good quality hunitng flintlock pistol for 50 yards and under, probably under depending on the killing ability of the pistol.

Re: Flintlock Pistol Muzzle Velocity

The guy to ask may be Mark KW. He seems to have a ton of knowledge about such things. He posts more on the traditional side. I asked him some stuff about flinter pistols and he was really helpful.

The wife (at my suggestion) bought me a Traditions trapper kit for Christmas. I'm kinda experimenting with a build and did not want to spend a ton of money and screw it up. If I get it together the way I like I'm hoping to buy a kit later from TVM and put a better quality weapon down the road. I'm really not confident enough to go from scratch. I'm more of a wrench and socket guy......wood scares me!! Good Luck!!

Gosh a 10 inch 50 cal barrel with 100 grains of powder. Powder and bullet must have taken up the bottom 4 inches of barrel, leaving only 6 for the bullet to traverse.

Re: Flintlock Pistol Muzzle Velocity

also take notice that the increaase of velocity from 90 grains to 100 grains at the 50 yd mark, is practically nil

I think that powder would probably burn more efficiently behind a larger caliber bullet/ball.

I've been thinking about a 58 or 62 caliber flint pistol.
