Are the newer Nosler Accubonds, mainly 6.5mm 130 grain and 7mm 140 grain, constructed differently than they used to be? I tried them both in 6.5mm and 7mm when they first came out but I haven't in a while. The first 6.5mm 130 grain bullets I tried would make a very small entrance hole and a very small exit hole with no blood trail. The 7mm 140 grain bullets would be very explosive on entrance but a small hole on exit.
