Redding make a 25-20 trim & forming die that apparently is a useful step between 32-20 and a full size 25-20 die. I thought about getting one to convert 32-20 to 218 Bee, as a mid point to neck it down. Didn’t need to as I used a 243 die (stem removed) to help form the neck. Pushed the 32-20 case into the 243 die with a short bit of dowel resting in the shell holder then tapped the case out. Then full length 218 Bee die to finish before fire forming. I annealed the virgin brass then again after fire forming.
