Folks- may be odd question but need some help. I've looked on the Remington web site but could not find the answer I needed. I've recently got a new scope for my REM 700 (308 WIN) and still have same concern as difficult to get a tight shot group using 150 gr core-lokt. However when I shoot 150 gr UMC shot group is tight. According to remington web site the ballistics are the same for UMC and core-lokt. My concern is no info on the UMC expansion and all info on UMC refers to varmint/target shooting only? Can you hunt deer with UMC ammo or is my issue with the core-lokt all in my head?
