[QUOTE="J E Custom, post: 1440964, member: 2736"] [QUOTE="bigedp51, And stop thinking only your opinion matters in a reloading forum. And go to Benchrest Central and Accurate Shooter and catch up with the rest of the world.[/QUOTE] You are so interested in being argumentative and What everyone else says that you did not even read the post. I said my opinion was just that, MY OPINION And you Don,t apparently have any experience to form your own opinion. You just keep quoting everyone else. You have lots of pictures and most if not all are wrong, like the primer being used to head space and the fine example of banana shaped loads. I for one have never seen or loaded banana shaped ammo. Mainly because it wont chamber. I have said many times that full length sizing was necessary for some applications and neck sizing for other applications. why would I subscribe to both if there were no benefits to apply the one that worked best for the application. I will try to explain one more time for your benefit, and then I GIVE UP !! This is a thread about Concentricity right? The most concentric thing to the barrel bore is a properly chambered chamber. When a cartridge is fired in this chamber It to becomes concentric. If the case neck is turned true, Then the outside and the inside of the neck are now concentric to the barrel bore. When you order a set of custom dies, normally the die maker wants at least 3 cases that have been fired at least 3 times to assure that they are a perfect fit in your chamber. So now you have a perfectley concentric chamber, and a perfectly concentric case including the shoulder, OD of the neck and ID of the neck and everything is concentric to the barrel bore. all of this has .0000 run out and you have a perfect set of dies based on your perfect chamber. You should have .000 head space. so everything is perfect (Or as perfect as you can get). The round will still chamber and you want to full size the case so that It is no longer a perfect fit, and in addition You bump the shoulder even though it did not need to be bumped so that it fits even worse? I don"t see anything about this process that produces concentric ammo consistently. it does make semi autos function better and with no problems. So It is my belief, that if you want concentricity in your ammo there are things that can improve the quality of your loads,you should also have concentricity in everything else to achieve concentricity in the first place. In addition to all of this concentricity of chambers and dies the loader still has the responsibility to load concentric ammo. DONE:rolleyes: J E CUSTOM [/QUOTE]
