I've been trying to sight in a new RRA 6.8 Upper on a RRA National Match Lower with a Bushnell Trophy 1.5 - 6X Scope. I am using Hornaday 110 gr loads. However, I can't seen to get the rifle to group and I get also have cases that don't eject. What's the reputation of these Hornaday loads? @ $29 a box - I can't stand the pain... Regards,
