Quick question

I have never done any fire-forming... since i dont know much about it i have a question. Would fire-forming new brass make a difference in accuracy vs just sizing with a FL sizer. again, im not educated on the subject thats why i am asking. From what i have read, its only necessary to fire-form with wildcats and AIs and such. Correct?

Re: Quick question

Yes, that's how I see it, for the 'wildcats'. A standard case would still slightly 'form' to your particular chamber, not that I see much benefit for the average hunter/shooter.


With new cases I would just do the standard 'neck size' to ensure the mouth is round, then trim, champher/debur & load away.

Fire forming usually helps the accuracy if it is loaded correctly after fire forming.

Most of the inaccuracy of factory ammo is the load it,s self. some rifles do very well with factory ammo and full length sizing so try what you have and if accuracy is acceptable go have fun.

Wildcats are not the only cartridges that benefit from fire forming and load development.

I always run new brass through a full length sizer before loading and weight sort for best results.

Re: Quick question

FL sizing will not bring fired brass back to initial pre-fired dimensions/capacity, even if that brass was FL sized before 1st firing.
What makes sense is to load develop with brass that is stable in dimensions.
So fire the brass a couple times, sizing as you always plan to, and then move into load development with stable brass.

Ok that makes sense. So if you were to start with a brand new batch of brass for a rifle ( in this case a 270 that will be hunted with out to around 400 yards) what steps would you take? I feel like fire forming to the chamber, in this case would not hurt by no means but is probably not necessary...

That is correct. I size new brass just to weight sort and batch it. it also rounds up the necks and puts uniform tension on the bullets, It may not be necessary but I find that it eliminates most of the flyer's when loading. the first time. This also saves money and components because most of the time accuracy is good enough to hunt with the first firing. After that, sizing just enough to chamber is my normal
procedure for working up a pet load.
