[QUOTE="Tidesloe, post: 2755545, member: 47761"] I’m about to have my 300 SS chambered as soon as I get the guy chambering it a dummy sent in. I’m trying to get worked out exactly where I want the lands to be. I’m not limited by length, as it’s gonna be an XM action, and I will be shooting 215 hybrids. After necking up 2 pieces of brass I realized I’d pushed the neck back a little bit. Nothing fireforming won’t cure. What should the min and max case length be on it for future reference? Another question I’ve got is how many fireforming loads “ should” it typically take to fully fireform ADG brass, and how much should I expect my brass to grow until fully fireformed? I went with a mechanical ejector on this build an fully fireforming might potentially be a little more critical to dependable ignition. [/QUOTE]
