In one of my other threads I have mentioned that I'd measured the ID of my Hornady .45ACP sizer/decapper die and compared it to my RCBS die. It was clear that the RCBS Inside Diameter (ID) was smaller- hence size the cases "tighter". The ID of the RCBS was several thousandths smaller (~.006"). This did have a direct impact on the tension on my bullets. I also put a RCBS resized case into the Hornady die by hand and the room for wiggle was amazing. On the other hand the Hornday resized case would not go into the RCBS by hand at all.
Has anyone seen much variance like this in sizer dies? With Hornady?
