I tried searching for this topic, but this is all I got.
My question is, are there any disadvantages to neck sizing brass for use in a bolt gun (obviously the same bolt gun that the cases had been fired in)? I've heard about how the accuracy may improve for neck sizing, and brass life may be increased, but I don't want to spend the money on a neck sizing die if it's not really worth it to do so |

The advantages if any are found as stated above, less wear on your brass and possibly better alignment for the bullet to the bore for the accuracy minded reloader. The disadvantage as I see it is that you will after some number of firings need to full length re-size. For me I have done both and now just full length with minimal bump to the shoulder. That way all my ammunition is always as close to the same as I can make it.

That (needing to bump back) is always mentioned but personally I have not had to do it. I had brass that was neck only sized over 10 times in 2 different calibers and never had to bump back the shoulders. Maybe I was lucky. Usually the necks would split before any resizing was needed. BTW: The ones that were over 10 were annealed. If you don't anneal your necks may start to split around the 5th neck sizing. Of course this varies. I would wait until I started to get split necks then would anneal the entire lot.
I have read a few accurizing articles that state "switching form full length sizing to neck only is one of the if not the biggest (single) difference maker when it comes to shrinking group size." This has been my personal experience too. Draw backs: Not all bolt action rifles are compatible. You may find one that will not allow a neck only sized case back in. I've also had a couple that the bolt had a little more resistance than what I would want if I had to reload quickly for a fallow up shot on game. Normally with neck only sizing you should feel a little resistance when closing the bolt but it should not be "hard to close". |

How do you control how much you bump the shoulders back? Is it a special die, or is it just all in the setup of the die? If it makes any difference, this is for .22-250 I measure the fired case with a Hornady/Stoney Point gauge then adjust the FL sizing die for the desired bump. |
| When I bought my 280AI I also bought the three die set of Redding dies. I now only FL size brass when it is new and use the Neck sizing die the rest of the time. I noticed that my groups shrank when I necked sized only. Also the brass lasts longer as the FL sizing tends to work harden the brass a bit quicker. Annealing the brass certainly helps though. |

I've heard about how the accuracy may improve for neck sizing, and brass life may be increased, but I don't want to spend the money on a neck sizing die if it's not really worth it to do so The guys that shoot for the ultimate in accuracy, (bench rest), full size their brass exclusively. I am not a bench rest shooter, but I have found after experimenting with a number of calbers in bolt guns that I can make the most consistent ammo with the least amount of runout by FL sizing. If you are not pushing your brass with high pressures, and you just push the shoulder back a couple thou each time you full size, the brass should last for quite a few firings. A Redding or similar FL sizer that has the option to use the proper size neck bushing is a big help. You can control neck tension, you are not over sizing the brass then, and the bushing floats to help keep the neck in line with the case center. JMHO.
