[QUOTE="Mikecr, post: 955418, member: 1521"] I take it this is your measured OAL at touching the lands (OAL-T)(your goal). Only bullet bearing is gripped by the neck, and this bullet doesn't have a full cal(.224) of bearing to grip anyway. Of the .689 OAL, ~.060 is boat tail, and ~.421 is nose, so your bullet bearing is ~.208 Your touching goal: 2.285 OAL-T minus 1.75 of case length in OAL-T = 0.535 of loaded bullet outside neck 0.689 BL minus 0.535 =0.154 of bullet inside neck minus 0.060 base =0.094 bearing inside neck (grip) which is ~3/32" It's not much, but it may be enough for your use. I single load everything & wouldn't sweat it. [/QUOTE]
