Hi all, I need some advise. I'm loading 7mm rem mag, Hornady 175gr ELD-X. I measured the max overall length by starting a bullet into a fired case. I can push the bullet in with my fingers but it is still snug. I chambered the round to use the lands to push the bullet in. When I removed the round and measured it, it had a COAL of 3.448". The book call for a COAL of 3.290". This gives me a bullet jump of .158". I know this is not the most accurate way to measure, but I think it should be close. Is this is right, .158" seems like a long jump? what would be a better COAL? I'm thinking around 3.245". What say you experts?
