The MM-180 Sharps has now been attributed to being produced at the Selma Arsenal according to RBTRF IV. I have been going through the Sharps bullets and have seen a very close resemblance of the MM-180 and MM-186. The bullets profiles are pretty much dead on, the sizes of the MM-180's and MM-186's are close, and comparing the bullets I believe they may be one and the same. Would appreciate comments and thoughts on these two bullets being the same.
