This is the target when I was checking my Remmy 750 to determine what ammo it liked. I made a mistake though. I wrote Win Bal SP twice. The bottom right was actually Remington Core Lokt.
All were .30-06 150gr. The middle target I did open sights after I tested the ammo. I have look-thru rings, in case you're wondering.
Obviously it liked the Silvertips. Figures. The most expensive AND they are now discontinued.
But this is a good exercise as I've found that rifles "like" particular ammo.
