Heavy conical for flinter

[KW]

Hello all. I was looking at doing a little experiment and was looking for a conical or a conical mold for a 50 cal. flinter in the weight between 600-700 grns. Of course I would work the load up very, very slowly. Just thought that it might be interesting, the rifle I would be using will be a RMC AccuSport LTD with a 28" barrel with 1-28" twist. Any thoughts?

NEI will make a mold for ya if you can't find whatcha want.

  Gosh KW your ontoo sumpthing there
 Those old govrenment studies from 200 years ago,,and that darn greenhill formula was made for cannon anyways!
 I guess bullet makers like LEE and LYMAN and Thompsen Center never did try getting a REALLY LONG Bullet too spin just right with a "fast twist"  "flint lock" gun. They may have overlooked those kind of stats,,You may be right.

I like the super glue suggestion crow_feather Wonder if they would really stay together??? Hmmm....... Was looking at the Lee and Lyman molds. Didn't know if a special one was needed, but I guess any flat base would do. Guess I was just looking to hard for what I needed. Lostid what is the greenhill formula??? I haven't heard of it before.

The Greenhill Formula is a simplified method for determining mathematically the amount of spin necessary to stabilize a bullet. It was worked out in 1879 by Sir Alfred George Greenhill who was a Professor of Mathematics at Woolwich and teaching the Advanced British Artillery Officers Class.

It was considered satisfactory for bullets having a density of .392 lbs/cubic inch or greater. (Lead has a density of .409 lbs/ cubic inch, and copper has a density of from .318-.325 lbs/cubic inch, depending on the alloy.)

It makes no allowance for nose shape, considering round noses and all spitzers and spire points as the same.

It does not work for bullets having a density below .392 lb/ cubic inch. All copper or brass solids and most heavy jacketed bullets have average densities below .392 lbs./cubic inch.

The formula was a shortcut and was useful at the time, as most bullets were roundnoses and were lightly jacketed, if jacketed at all.

The Greenhill Formula is accurate when used in the context for which it was intended, but many folks who use it today have forgotten, or never learned that context.

Thanks quickdtoo I will look into that formula. Amazing how those old timers way of thinking can still be used today in our "digital" world.

 some of washingtons snipers used  conicals clear back in the   revalution at Monmouth  even in thier smooth bores

I have to ask???
What on Gods Green Earth are you gonna
shoot with them. Dinosaurs are extinct man!
That will offer up some pretty good recoil I'll wager!

  Hmmm wonder what T-Rex steaks would taste like No I had at the time a deal going for a 50 cal flinter (Accusport) so I was looking at just experimenting with heavy loads with it. But that fell through, which is good becasue thanks to roundball and his .58 flinter ;)I am now going to get a T/C Custom renegade flinter in .58 and work up a good rb and conical load for it.
