WCH: Hagel was a favorite of mine! I recall his articles on long throating the 7 Rem mag and the 300 Win Mag as well. Wooters too.

I also ran a few long throat 300 win mags.

As I recall, Etters was using dots in the reticle for long range before most of us knew what dots were... grin




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
