I am looking for some general information on muzzle loader ballistics (velocity and energy at 50 yds out). Currently I shoot 100 grains of powder (2-50 tablets), old style percussion cap(not a shotgun primer)and a 240 grain Sierra Pistol Bullet tucked inside a plastic sabot! I suspect it is about 1800 fps and 1400 ft-lbs of energy. Any ideas or point me in the right direction!

It's called technology, Don. Each to their own...
I have a stainless steel 50-caliber Thompson/Center Omega with a 28-inch fluted barrel, 1:28 twist. A 250-grain Hornady SST/ML bullet in Hornady's Lock-N-Load Speed Sabot over three 50 grain-equivalent pellets of Triple Se7en chronographs at 2,130fps and shoots into 1.372" three-shot groups at 100 yards. Using an exterior ballistics chart and a 100-yard zero for its Leupold UltimateSlam scope, the bullet is 0.4" high at 50 yards, 1.2" low at 125 yards, 3.2" low at 150 and 9.7" low at 200 yards.
That chart is on Hornady's website and works for any firearm. If you know your bullet's BC and TRUE muzzle velocity, it will do the calculations for you.

Crossbows can't be too bad or stodgy old Pennsylvania would never have legalized them! Thanks to our Game Commission, I now can join my son in the woods during archery season because my arthritis prevents me from drawing a traditional bow.
Oh, the crossbow thing went down hard here, too. It took a couple of years and the "real" archers said it would clog the woods with us stupid gun hunters when they really objected to having to share the gravy with more people. During the firearms seasons for deer, I go hoping to see one. During archery season, I go hoping to see a NICE one. And hunting in a mesh camo long-sleeve shirt beats wearing multiple layers to stay somewhat warm.
But I haven't hunted during archery season in two years. When you can bag one three Thursday evenings in a row in less than one hour each time, that's just too easy.
That oughta stir the pot!
