TABLE II-A These are Dr. Guinn's showing variations of antimony, silver, and copper content of individual WCC Mannlicher bullets from the 4 lots he tested. He rightly called the results evidence that Mannlicher ammunition had no homogeneity from lot to lot or bullet to bullet.

TABLE II-C The results of Dr. Guinn's tests on 4 fragments from each of 3 individual WCC Mannlicher bullets. He cited these as evidence of intra-bullet homogeneity. Note huge variations in antimony content, especially in bullets #6002 and #6003. Note also large variances in silver and copper content. Compare these with Table III in Appendix B. It appears that Dr. Guinn based his key conclusion about homogeneity on the fragments of these three bullets.

Comparison of Tables II-A and C (1) Selected fragments from each of the 3 bullets tested varied from one another more in their antimony content (Table C) than did the 2 whole bullets tested from Lot #6000 (Table A); (2) Selected fragments from bullet #6002 varied from one another more in their antimony content (Table C) than did 3 of 4 whole bullets tested from Lot #6001 (Table A); (3) Selected fragments from bullet #6002 varied from one another more in their antimony content than did 2 of 4 whole bullets tested from Lot # 6002 (Table A); (4) Selected fragments from bullets #6002 and #6003 varied from one another more in their antimony content than did 2 of 4 whole bullets tested from Lot #6002 (Table A); (4) Selected fragments from bullets #6002 and #6003 varied from one another more in their antimony content (Table C) than did 3 of 4 whole bullets tested from Lot # 6003 (Table A
