Archived [ARCHIVED THREAD] - Cor Bon 55 grain
Posted: 4/29/2009 2:04:05 PM EDT
I am about to try some of the 55 grain mil spec CorBon ammo. Does anyone use much of it? Is it good quality? Supposed to be Winchester cases, so should be GTG for reloading./

I've had no problems reloading it.  I was getting pierced primers and flattened primers in a couple of my guns.  We Chrono'd it, and it's clocking slower than XM193.  My guess is they're using a fast burning propellant that's giving pressure spikes or very soft primers.
