This list of abbreviations for bullet types could go a long way in trying to standardize descriptions. I know I am going to go through my 15,000+ catalog of my collection on Excel and revamp my usage which has not always been consistent over the years for the same bullet type.
I can add a few more to the list.
MP–Metal Point (Only the front half of the bullet is covered)
I’m sure there a lot more propriety bullet types that haven’t been listed, like the Winchester’s Talon. Many of these may not have “Official” abbreviations. I suggest we all go through the catalogs and see what the manufactures have used as abbreviations over the years.
I think this would make a good article for the IAA Homepage or even the Journal. For either of those uses we should really illustrate each type with either a cut from a catalog or an actual picture. Where available, a sectioned bullet to show the internal construction would add a lot.
I’m willing to compile the information and illustrations into such an article, but I would need help with the images. I can handle U.M.C. and Remington. If everybody would send me what images they have, especially sectioned bullets, I’ll get started. Scans should be at least 150dpi Color (even if the catalog page is B&W). Send any images (with ID) to my email below.
