The only catridge I have used the Silvertip in is the 30-30 in the 170gr weight. My Model 94 shoots them better than anything I can reload for it. It also performed well on the deer I have used it on so far giving complete brodside penetration. My rifle is a Black Shadow with 24 in. barrel and has an old 3x Weaver on it. It will shoot three of those factory Silvertips into 1in at 100 EVERY time if I do my part. So far I have no complaints with either bullet or rifle.
