Fireforming

Re: Fireforming

Are you forming a wildcat based on the 300WM, or just firing the brass to fit your 300WM chamber?
If it's a 300WM, just load up whatever load (or loads) you want to try, and shoot it. They can be mild or max loads. It won't matter. Are you neck sizing after this?
 
Re: Fireforming

yeah just standard 300 win mag brass nothing special. I also was going to try Redding Comp dies for the first time. They look incredible and I like good quality tools. Should I fireform the brass with the bullet touching the lands?
 
Re: Fireforming

Load them up like the book says and see how they do like that. Does the rifle have a custom barrel / chamber? Sometimes when you run the bullet out long for a factory chamber, they don't feed through the magazine. If it's a custom chamber / barrel depending on the reamer it was done with, you may not need to move it much at all.
