How is the chamber lead angle determined?

[craneman]

Can anyone describe how to measure the lead angle of of a chamber cast?
I have a new project on the bench, it is supposed to be chambered in 44-100 Remington straight and I am hoping to build this into a dedicated long range paper patch rifle. There have been a number of people changing lead angle to 7 degrees for paper patching and would like determine what I have so I can see if there is anything I might want to change before finishing this build.
It is sporting a #4 Green Mountain barrel with 1-17 twist on a high wall action.

   

Thanks for any and all input!

Throw the whole thing away and run Todd, don't get caught in this 44 maze, of which there is no way out.
If Kurt doesn't pop in here after a bit send him the picture .

I know Don, I am a glutton for punishment and can't seem to leave well enough alone!
I was hoping for some of Kurt's wisdom as this is right in his wheelhouse.

This big storm hitting you Don?

Man Don; I hate to give away all of my secrets and give my competition an advantage over me for the few seasons I have left.

That mess is headed this way too, are you calving right now?
You should have green pastures this spring!

[craneman]

That sure is a good looking bullet Kurt. I can't remember, is that a prolate of your own design?

Besides Kurt, no more than I have shot this last year I don't think I will qualify as competition!
