I’ve been shooting Ballistic Silvertips for quite a while but I have been thinking about changing to a new round. The majority of the deer I’ve shot with them have been DRT but the ones that have ran off left little or no blood trail and no exit wound, although none of them have made it more than 50-60 yards. What are some suggestions for a new bullet to try? I’m shooting a 7mag and 7-08.
