Home Forums Hunting & Shooting Express Rifles and Big Bores Only Updating the 404 Ruger African project

Anticipate this will be the last update before firing tests produce chrono data over the weekend. Found out the easiest way to form development cases (without correct headstamp) is 1 pass through the 404 Jeffery resizer (shimmed to correct headspace) with a tapered expander button. Small but discernible difference in neck diameter and thickness.
