If you neck size, have you seen an improvement in accuracy over full length sizing. I'm thinking of going with a Redding S die to see if I can reduce runout, but it's a pretty steep investment to get started with the cost of bushings. One thing I am definitely going to buy is the competition seater. I have one in .223 and I love it.
Edit: I should have said that this is for a new Savage Model 10. I've always full length sized my ammo, but I wouldn't mind trying something new. I'm thinking of giving the Lee Collet die a chance. It's highly favored or hated by some, but it's a small investment (or loss) and probably worth a shot. I can always pop for the S die and bushings later. I have a steady supply of free 308 brass anyway, so that's something at least! |

I load my .308 for use in semi-auto rifles and bolt actions, so I'm required to full-length resize every case unless I want to keep my ammo separated based on what type firearm I use it in.
Neck sizing only is limited to bolt actions and that ammo must be used in the rifle that fired that brass to begin with. It fits that chamber for a couple reloads before it must be full-length resized to fit. Once the bolt resists closing on "neck sized only" ammo it's time to full-length resize that brass. This reloading technique usually improves accuracy because the ammo is a perfect fit to the chamber. |

If you want to get started with neck sizing, use your full length sizer.
Just don't screw it all the way down in the press, perhaps use a washer made of shim stock, to raise the die 0.010" (just a WAG). This should prevent resizing the body and still size almost the entire case neck. You will likely still want to use your expander ball to keep the neck ID uniform (it pushes the non-uniformities to the outside of the case neck. . |
| I shoot bolt only and one gun with my 308. One reason I neck size is to make reloading easier and faster. However, you will still need to full length size them after a few loadings. What happens is the bolt will act like it's binding when closing which is an indication you will need to push the shoulders back. Another reason is that it does reduce some of the stress on the brass so it may actually last for a few more loads too. As for better accuracy, I really can't tell that much........ |
