Mr. Eisenberg. Did you test the bullets for yaw?
Mr. Simmons. Yes; we measured yaw also, and all measurements of yaw were also small. We had no values in excess of 2 degrees, and many values were less than 1 degree in yaw, indicating that the round is quite stable.
Mr. Eisenberg. How did you test for yaw?
Mr. Simmons. We took spark shadowgraph pictures at various stations down range from the muzzle, so that we actually have pictures of the position of the bullet relative to the top and bottom of our range.
Mr. Eisenberg. Did you bring those pictures with you?
Mr. Simmons. No; I do not have them with me.
Mr. Eisenberg. Could you furnish those to the Commission at a later date?
Mr. Simmons. They could be made available later. I would like to point out these are not pictures, however. They are on large pieces of glass, and they are not photos.
Mr. Eisenberg. Can they be read by a layman?
Mr. Simmons. That I do not know. I do not read them.
