Default Muzzleloader Velocities

Guys I know this is a really basic question but what are typical mzl velocities. One would think that it would be easy to "google" but I've not come up with anything other than stuff talking about "at muzzleloader velocities" and its pretty vague. SOOO....If any of you have chrono-ed your loads could you please tell me what you're getting. I know that the guy using 85gr and a roundball isn't going to be anywhere near the Knight shooter with 150gr pyrodex and a 300gr sabot. But I'd like to get a feel for exactly how these things stack up with pistol-cartridge carbines and shotgun slugs. (Again, I know all three are completely seperate animals...I'm just trying to get an idea) I mean, are we talking about 300gr @1200fps or 250gr and 1800fps or what? Velocities place an immense role in terminal ballistics and without knowing "V" you're just fumbling around in the dark.

Thanks for takin' the time.

Hornady says thatthe 250 grain SST and and 2, 50 grain Pyrodex pelletswill give1890 fps at the muzzle. Hornady says that two Pryodex pellets and the 300 gr. SST will give 1770 fps.

I put a 250 grain SSTclearthrough both shoulders of an old 350 pound (weighed) boarusing100 grains of Pyrodex RS. He expired instantly, unusual for a hog.

Ashooter I know has chronographed these loads and says it ispossible to get over 2000 fps with three Pyrodex pellets and the 250 grain SST bullet.

Give this a try Soilarch - http://www.handloads.com/calc/

Just plug in appropriate numbers and you'll get your answers

I used about 90-100gr Pyrodex RS with a 240 gr xtp - kills deer dead, esp. if hit high in the shoulder

You can go to powder manufacturers' websites and they'll usually have some load data:

When you consider velocity also consider energy. So when we talk about velocity we need to know the weight of the projectile, the ballistic coefficient, and the powder charge being used. Then with some set standards from known chronographed loads we can figure energy. Actually many of our posters who are kind enough to post chronograph results have made a wealth of information reference bullet performance.

As mentioned, many of the companies post speeds with set loads. If you have a certain load you are curious about, perhaps one of the members have information on it already..

Thanks guys, man I feel dumb for not checking handloads.com. There's no set load in question cayugad...I'm just comparing them to some of the "other" cartridges out there.

Thank you very much.

My TC thunderhawk, with 150 gr of reg. pyro pellets and a 250 gr traditions T-Shock XLR, lit up with an RWS musket cap runs 2070 fps. sighted in 1" high at 100 is 13" low at 250 yds.

If you look on the jug of T7 it will tell you.

I have a Ultimate Muzzleloader, 200grs Pyrodex, 300gr Shockwave 2340fps. If I up it to 250grs of Pyrodex it goes to 2470 Fps
