[QUOTE="PartsJr., post: 2783086, member: 87242"] I’m looking for suggestions to get better hand loads for my .280ai. Gun: blue printed Rem 700 26” 1:9 Brux barrel Pushing 139gr LRX 3100fps using 61.5gr H4831sc I measured my fired cases (3rd or 4th firing) at the neck and get .315” My cases measured 2.520” in length b4 and after shooting. No case growth. Cases were lubed (sprayed: case mouth, neck and body) using One Shot. After full length (RCBS FL die) resizing I bumped the shoulder .002” back. My measured case length after FL resize is 2.525” or .005” longer. After FL sizing my neck diameter measured 2.309” or .006” smaller than fired round. After seating a .284 cal bullet my neck measures .312” Should I be getting this much stretch after full length sizing? I would prefer to minimize this and avoid trimming. Is my neck tension too tight? Suggestions are welcome. Thanks. [/QUOTE]
