Title: Projectile Questions?
Post by: Spotted Bull on May 14, 2008, 06:50:18 PM
Being somewhat new to this front-loader stuff, and not one to experiment on my own that much, I was wondering if I can use conicals, etc in my .50 Kentucky flinter. It has a 1:48 twist.

You can shoot conicals in that gun with that twist, but you run the risk of embarrasing the gun to the point it may missfire or shoot por groups untill you start feeding it PRB's :)

A 1:48 twist is supposed to be a universal twist that you can use with either RB or conicals.

Seldom works out that way, however.

RB,

I think you'll find that using the patched round ball will be far more accurate then a conical.

Also, experimenting and working up a load with either (PRB or Conical) will be neccessary.  This holds true with any muzzleloader. :shake

All of my 1:48 twist guns shoot conicals fine.  My shoulder prefers patched round ball  :shock: .

One note to consider - some shoots or ranges allow round ball only.

yes your rifle will shot conicals .
and yes it will do it accurately .
even a slow twist barrel will shoot  conicals and do it with reasonable accuracy  but  the rifling must be acceptable and  you must find the correct conical for your rifle .

 in my 1in 66 twist  long rifle i use maxi's for elk .  Even in the slow twist they seem to stabilize fine and will hold about an 8 inch pattern at 100 with them .
 But the key is finding the right conical  and load . That takes time

It's a conical style bullet invented to increase the speed of reload in military "rifled muskets", while preserving the accuracy of those muskets,

It's actually spelled " Minié ball "

It has much heavire mass than a roundball of the same caliber, and therefore a much more powerful penetration. It may not be as stable  ballistically as a roundball

From Wikipedia:


The Minié ball (or minie ball) is a type of muzzle-loading rifle bullet named after co-developer, Claude-Étienne Minié. It came to prominence in the Crimean War and American Civil War.

Invented in the 1840s by the French Army captains Montgomery and Henri-Gustove Delvigne, it was designed to allow rapid muzzle loading of rifles, an innovation that brought about the widespread use of the rifle as a mass battlefield weapon. The design of the ball had been proposed in 1823 as the Cylindro-conoidal bullet, but was not adopted.

It was a conical-cylindrical soft lead bullet, slightly smaller than the intended firearm barrel's bore (see caliber), with (originally) four exterior grease-filled grooves and a conical hollow in its base. As designed by Minié, the bullet had a small iron plug in the base whose purpose was to drive forward the bullet and, under the pressure of powder gases, obturate the bullet to fill the hollow space and expand the lead skirting to grip the barrel's rifling. As finally adopted by the United States Government before the Civil War, however, the skirt of the bullet base was made slightly thinner and the plug was omitted, as the pressure of the powder gas alone was sufficient to expand the skirt to engage the rifling. Also, as adopted by the U.S. Government, only three exterior grease-filled grooves were used, instead of four.

".and he tried every thing to get it to shoot round ball as good as it does with a mini. "

Might be one needs the rifle twist to turn the other way on that side of the equator?
