I have been working on gearing up to reload the 43 Mauser cartridge which is my first kind of "non-standard" round I have ever tried. Last night I thought I had everything I needed so I went ahead and resized all of my cases. After doing so I went to trim. I have the the lyman case trimmer with the power adapter (https://www.midwayusa.com/product/795961/lyman-universal-case-trimmer-kit-with-9-pilots). The issue here was that I could not easily get the rim of the case to fit under the two holders. I think there are two issues here. First is that it is a really large rim (.586"), and the rim is also raised a bit from the base of the case. Eventually I figured out how I could just get it to slide in if I held one of the spring loaded jaws on the holder all the way back. This was very difficult and it took me and hour and a half just to trim 40 cases. Also I had issues with the cases not being fully gripped and falling out. I have had other issues with this trimmer in the past such as it not fully securing 223 brass. I would be open to replacing it, however I am unsure as to what would fit the 43 Mauser case. Any suggestions? I kind of liked the Hornady trimmer since it uses shell holders until I read that I will need Hornady shell holders (not sure they even have one for the 43 Mauser.)
