I read that thread before. I'm not sure how good a job a 7.62x39 sizing die can form a 7.62x45 though. They have different shoulder angles and tapers. I guess they just keep squeezing the case till it chamber, fire form, and neck sizing afterwards. I don't quite like this approach, especially for a semi auto. I would rather pay for a real sizing die and do it right.
Reading the thread again makes me realize that they must be using 7.62x39 seating die to seat the bullets. That's what I need to know. Thanks.
