[QUOTE="vancewalker007, post: 2435651, member: 66917"] Oh I'm not worried, hahaha. I think what we see here is 1. The efficiency of a short fat case and 2. The limit of diminishing returns of a hair more powder. The 180 VLD H in the 3 7mm LRMs I have loaded for only get 50-70fps more velocity out of 10-11gr more powder using a 180 VLD H over the numbers McWhorter is showing. So if you can reliably and safely get 3000fps or better out of a 180 VLD from 10-15% less powder than it takes to get 3080ish fps I say that's a win. I think a lot of people under estimate the value of that short fat case structure. I never used RL26 in the LRMs so maybe that powder would jump the fps some but I still think 70-71grs is in that diminishing returns region where you need maybe 5-8 more grs for a more meaningful velocity jump.
