Mr. McCloy. Yes.
Mr. Eisenberg. Mr. Simmons, I find there are three shims here. You mentioned two. Would three be consistent with what you were told?
Mr. Simmons. I was told two. These were put in by a gunsmith in one of our machine shops—rather a machinist in one of our machine shops.
Mr. Eisenberg. Mr. Simmons, I wonder whether you could take these shims back after I have marked them to find out whether the three had been placed?
Mr. Simmons. Yes.
Mr. Eisenberg. I am marking these 576, 577, and 578. They consist of three shims in three small envelopes.
(The items referred to were marked Commission Exhibits Nos. 576, 577, and 578, and received in evidence.)
Mr. Eisenberg. Mr. Simmons, did you have a test run to determine the possibility of scoring hits with this weapon, Exhibit 139, on a given target at a given distance under rapid-fire conditions?
Mr. Simmons. Yes; we did. We placed three targets, which were head and shoulder silhouettes, at distances of 175 feet, 240 feet, and 265 feet, and these distances are slant ranges from the window ledge of a tower which is about 30 feet high. We used three firers in an attempt to obtain hits on all three targets within as short a time interval as possible.
I should make one comment here relative to the angular displacement of the targets. We did not reproduce these angles exactly from the map which we had been given because the conditions in the field were a little awkward for this. But the distance—the angular distance from the first target to the second was greater than from the second to the third, which would tend to correspond to a longer interval of time between the first and second impact than between the second and the third. The movement of the rifle was greater from the first to the second target than from the second to the third.
