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).
