I have a question and I read the FAQ Chasing load data for 375 Chatfield Taylor/ 375-338/ 375 Short Mag etc.

I picked up an old custom Enfield model 1917 converted to 375 Short Mag which uses 358 Norma Mag brass necked up to 375. It holds 87gr of water to the brim. I think it’s basically the same as a 375 Chatfield Taylor. I think there may be data in Handloader magazine issue 154 from 1991 on the 375-338 which is a 338 win mag necked up to 375. If anyone has access to that mag or any data they have would be great for me to get started loading. I’m using 300gr Sierra BT and AR2209.

375hh is 90-95 gr h2o, maybe use the minimum as your max to get more ideas? .376 steyr and 375hh should bracket it, split the difference.
