It's a berger - Berger Long Range Hybrid Target 6mm Caliber 110 Grain Long Range Hybrid Rifle Bullets

I have shot lots and lots of bullets in several different rifles and calibers. When frustration sets in at the loading bench or zero line just grab some Bergers. I run several bullet brands but in many cases constant observation is required of target group quality because if it doesnt come in the yellow box it will more than likely ruin your day at one time or another.
