Robert White,

You asked for links to pictures.

http://www.ar15.com/ammo/project/Self_Defense_Ammo_FAQ/index.htm#OVERPENETRATION

This is from AR15.com.

Go straight to that or click on AR15 the top of their home page and AR 15 Ammo Forum FAQ's and that will take you to Ballistic Gelatin under choices for Defense.

All the photos you want of the 77 are included along with other cartridges' ballistic test photos.

Sorry. I forgot your request in the queries about the limited excerpts of Mr. Guthrie's article.

I trust that gives you the info you requested and more in fact. I's a long article so just keep scrolling as the info is scattered amongst pistol

tests, also. They are not the ballistic gelatin tests I have , but they should suffice.

Best
