ok i bought a box of hornady SST LIght Magnum 30-06 shells for my remington 7400 and i shot about 6 shots or so and they shot terrible so i just tossed them in my truck and thats where they`ve been for awhile but the other day while i was waiting to go into work i read the back out of boredome and it says there not supposed to be shot out of a semi auto gun. now why is that? they cycled fine in the gun i just couldent get them to group worth a flip. thanks for any info
