I have a bunch of new and some brass from another rifle that was discarded at my local range. How do you guys fire form brass to conform to the chamber to your rifle?

Is this brass the same caliber as your rifle? If it is, full length resize it, trim and load. If you are blowing it out to a new caliber, I load a light charge of WW 296 and put a piece of paper towel in the neck of the case and fire it. Custom fit instantly.

It is the same caliber. How much powder do you use? Curious as to how much noise this makes and is it ok to shoot in your basement to save a trip to the range?

Remington Cases, Federal primers

Topgun 3006

The OP is losing me here when he now says it's the same caliber, but again is asking the fire forming question. For what reason I would like to know since redgreen told him what to do in his second sentence when that is the case.

edmehlig

thanks for the input. I was told you should always fireform your cases to achieve optimum accuracy. If you guys feel it is not worth it, that sounds great to me. Saves me time and aggravation not to mention saving me some powder and primers etc.

Thanks for the input!!

The average shooter with the average rifle with never notice the difference in accuracy between full length and neck sizing.

***That's probably very true, but one who picks up cases off the range and doesn't full length resize them is probably looking for problems, including the fact that they may not even chamber.

Just full length size. Neck sizing just prolongs the life of the brass.

What type of accuracy are you expecting? If you're really talking about picking up once fired Remingtons, we're probably not talking about precision F-class ammo here... Absolutely no sense in going through the trouble to fire form to the same cartridge chamber. Just full-resize, and go shoot. I do generally give a "dry run" to new brass, where I'll full length resize, shoot one, then neck size and worry about load development once the cases are fitted (not in semi-auto's/AR's of course).
