This is a good topic which could turn into an ugly baby! Serious collectors, and I consider myself among that group, want to place correct identification on each bullet type. Unfortunately we are yet compiling knowledge. To me that is one of the great FUN aspects of the hobby.
Be it right or wrong, I coined the description of 'Bullseye' Enfield for a type of variant found in the Trans-MS area...the one with a couple of shallow grooves around the nose. This was done for the purpose of differentiating it from other 'Marshall, TX' Enfields. One of these days I hope we can place a proper name to this variant.
I also had a hand in naming the Loring Type 1 and Loring Type 2 Enfields which have been found in the camps of that general's troops in central MS. Once again, this is an expedient rather than an end. Local military preservationist took up the usage. It's just easier for us at this time to say we found six of the Loring Type 1's, than saying 'Today we found some of those, you know, the Enfields with kinda a real round nose, uh, sorta plug base but not really a PLUG base, uh, about .670 caliber, uh, you know the one's we dig around Canton' bullets.
I offer no appoligies for this. Mostly it's a local collector thing. More research and knowledge will reveal proper descriptive names in the future for the types we collect. As I said, nick-names are just an expediency for the time being. No harm intended.
