[QUOTE="QuietTexan, post: 2725054, member: 116181"] So.... you physically put all the cases inside a sizing die that is set below the max length of the chamber. Are you willing to try something new here? You're in a tail chase of sizing and trimming, so if you want to break the cycle you're doing to have to do something different. Don't size the cases. At all. None. Nada. Zilch. Nyet. Nein. "Just say no" to putting the cases inside a sizing die. Fight the urge to make things the same, let the cases be different for a few firings. Do not trim the cases either. Let them be the length that they are (the only exception is for safety if they're too long for the chamber, which they shouldn't be in an AI after the first firing). It won't hurt anything. Cases that have different headspaces and different case lengths are [I]absolutely, 100%, A-Ok [/I]to shoot. You might even be shocked at how well they shoot. Strip your bolt down and put the cases in the chamber. You must take the firing control group and the ejector out of the bolt, there's no way around it. No tape on the cases, no marker, nada, zilch, nothing. Does the bolt close? Then size [I]the neck only[/I] and shoot it again. Find an actual neck sizing die, or take the largest bushing die you have that won't touch this case at all and set it size about half the neck. Shoot and neck size until the cases don't fit. Don't worry that they're different lengths, don't size them and don't trim them until the cases don't fit anymore. Then you can "bump" the shoulders. Do it only 0.001" if you have a die capable of that. Get a Whidden click ring if you aren't used to timing a die accurately. There are a few other parts to this - don't eject the cases and let them bang into concrete. Don't let them fall into the mud or get stepped on. Basically treat them so you don't have to clean them, other than to maybe wipe them down in a rag. You don't need them clean because they aren't going into a sizing die. Use a nylon brush on a drill to hit the carbon in the necks before charging and seating, that's all the lube you need. [/QUOTE]
