    I currently have a 28" 9 twist CBI barrel with a little fac throat erosion! .145" freebore, I load 180 bergers at 3.156" .005" in 3091fps 70.6grns H1000, its a very good load but sometimes the bergers are hard to find so I would like some first hand info on the 190 matrix if anyone shoots them, Thanks.
