[QUOTE="OKBPS, post: 3337470, member: 45455"] Here are the loads I made up. 10 rounds each. All PPU cases.

Pulled bullet, reduced powder load and reassemble. Overall length of all rounds was 3.037 1. Sierra ProHunter 180 Spritzer, .308. Cases weighed from 150.3 – 152.1. Length was 2.1080 – 2.1105.
