280 remington into ackley improved
I am getting a new custom sako 280 ackley improved soon. Trying to get brass and dies. I see people talking about fire forming 280 remington brass. Some are even saying use cream of wheat. Can someone explain fire forming technique??

Why not just buy some Nosler 280AI brass?

As for fireforming, whether you use the Cream of Wheat method or simply load .280 Rem. brass with a mid to stiff powder charge of rifle powder and a .284 bullet, you're going to form that case to the new AI chamber dimensions which include a 40 deg. shoulder and minimum body taper. Buying the Nosler brass eliminates that step.

I just purchased a Cooper 280AI myself,and even though I have done some case forming in the past,it never crossed my mind to fireform 280 rem brass.I simply bought some 280AI brass,and I can immediately begin load development with no time and components wasted fireforming brass.

If you do end up forming your own I've had best luck with a faster burn rate powder and a mid range 280(not AI) load.
I also had a pard that tried to form nickel in his AI with poor results...

I believe Jarret loads ammo for this round too. Read up about his thoughts on it...

All you have to do when fireforming .280AI from .280 brass is simply shoot standard .280 loads in it. That way not only is it formed, but it's also fireformed precisely to YOUR chamber at the same time. I wouldn't buy the Nosler .280AI brass because of the higher price-even if it is better.

nosler brass is junk! won't take near the pressure rem. will and rem is the bottom of the barrel.

I haven't had a chance to fire any rounds yet using the Nosler brass,but I have done some measurements to check consistency,and I was very impressed.I measured 20 rounds randomly,and the neck thickness was within .0015" in all 20 cases.I bought this brass after hearing many positive results from other people that had used the Nosler 280AI cases.I have however read that some early batches of Nosler brass were not nearly as consistent as later batches.As to the hardness of the brass,I will be firing some test loads in the next couple of weeks.
