It's about 0330 in the morning after a routine shift and getting home of course I am having to look at and compare bullets to wind down. My dang dogs don't even want to get up at this hour. I have a MM-311 in my collection that measures out at .503 x .859 x 327 with a 2 cavity (conical). I realize the MM states a 7 cavity for the MM-311 and a 5 cavity for the MM-312 in which I have never seen these cavities in these bullets. I have been comparing these two bullets to the RBTRF IV 162 and 165 and does anyone have this/these bullets with listed cavities by MM or do they have the conical cone cavity? I personally believe these are the same bullet with a variation in length only and having a conical cavity.
The MM-302 and MM-303 which I have not been able to find for my collection list both as having a 7 cavity. Looking at the measurements in "Some Civil War Bullets II" the MM-302/303 are not very close in length to the MM lengths. Comparing Bullet # 156 in RBTRF IV the measurement falls in line with the bullets in Tom Stelma's book. My question is this two bullets with a difference in lengths or is this a single bullet with variants on the lengths? Whatever the concensus I am still looking for one or both of these.
Jim the reference to the Kerr is for you. >:(

I just realized something and rather than making a new subject I thought I would reply to an old thread that approached this subject. Pertaining to the question about MM302/303 I have noticed something recently that I believe clears this matter up a bit. The previous question was posed, is this two bullets with a difference in lengths or is this a single bullet with variants on the lengths? After looking at these for years I recognized something that now seems painfully obvious. The diameter on MM303 is much smaller than what is shown in the book. If you mic the diameter of the bullets in the book you will see that most match what is shown in the log below however MM303 shows it should be slightly larger than MM302, looking at it that doesn't seem to be the case. After measuring MM303 it appears to be slightly over 0.40", much smaller than what is recorded on the page. If you look in RBRF4 you will note that MM302 would cross reference nicley to #156 but there really isn't a great cross reference to MM303 until you realize it is much smaller than what is shown in the M&M book. Realizing it is smaller and around 0.40" makes it a match for #154.
In my opinion the answer to the question is they are two different bullets not solely based on the length alone but different calibers. (Tennessee Rifle Bullets)
