From my reading, forcing cones on revolvers tend to be larger,
because of the issue of indexing. That is, loose tolerances or worn
mechanism may result in a chamber not lining up with the barrel, Sot
he manufacturer just makes a big funnel at the on end of the barrel to
catch the bullet in, and guide it to the center of the barrel.

Of course they are larger. Now there are various things to
consider....

Thought you might like an additional problem...chamber throats along
with forcing cone angles (I ream to 11' btw)

"Forcing cone angle can be from 3 degrees to 45" Oy.

I just spent 2 hours trying to fix the bloody drawing. It doesn't
reuse line items - you erase point 4 and make a new point it is point
5. I'm up to point 1504, circle 359 - and it is still not even
approaching done. It looks "okay" but - unclosed circles, and such.
More problems than I can handle.

Practice makes Perfect my son. You wanted a difficult project to keep
you amused ..and you picked a very good one!

there is amused, and then there is frustrated. There's wire frame
and there is "sketcher" - solids. Wire-frame lets you draw a circle
tangent to these three points. Sketch doesn't.
As I have said, I could probably knock this out on the drafting
table with paper and pencil faster.
But I am exploring some of the other areas of the program.

Thats exactly why I retain a nice big drawing board behind me as I
type. And I have all sorts of Cad/Cam programs on hand. While
Cad/cam may be cooler and High Techy!...I have great..great difficulty
in efficently using any of them to design something. Which I can do
quickly and easily using the drafting table. Yah..I know..Im an
anachronism....shrug

And I do love computers...so this is..... odd.....


I can just see you at that drawing board, too.

Nicely sharpened mechanical pencil.

Licking? No. Now..the inside of my ears...they tend to get blackened
up. Ive had this trait to stick things inside my ear..absentmindedly
cleaning them as I think. Often times using things at hand.
Occasionally it will be a permanent marker...sigh.

"The socialist movement takes great pains to circulate frequently new labels for its ideally constructed state.
Each worn-out label is replaced by another which raises hopes of an ultimate solution of the insoluble basic
problem of Socialism, until it becomes obvious that nothing has been changed but the name.
The most recent slogan is "State Capitalism."[Fascism] It is not commonly realized that this covers nothing more
than what used to be called Planned Economy and State Socialism, and that State Capitalism, Planned Economy,
and State Socialism diverge only in non-essentials from the "classic" ideal of egalitarian Socialism. - Ludwig von Mises (1922)
