I sure most people here are familiar with the Winchester Silvertip. I’ve had this box for a while now and found it the other day and decided to give it a try. Out of the Sig, I got an average velocity of 947fps with a high of 972 and a low of 937fps. Out of the Beretta Nano, I got an average velocity of 914fps with a high of 924fps and a low of 894fps.
Out of the Sig P229, the first round into the bare gel penetrated 17.5 inches and expanded to .56 inches. No velocity reading but the recovered weight was 149.4 grains. The second hit the block at 968fps and penetrated to 17 inches. It also expanded to .56 inches and had a recovered weight of 149.8 grains. Both bullets were recovered base forward even though there was no sign of tumbling.
When shot through clothing covered gel, the first round had a velocity of 930fps and penetrated to 19 inches. The recovered diameter was .44 inches and weighed 149.6 grains. Round two hit at a velocity of 936fps, penetrated to 19.5 inches with no expansion. It did show some deformation of the nose and the recovered weight was 149.5 grains. Both bullets stopped nose forward but the gel showed tumbling midway through the first block.
Out of the Beretta Nano, the first round penetrated to 18 inches with a recovered diameter of .55 inches and a weight of 149.6 grains. No velocity was recorded. Round two had a velocity of 888fps and penetrated to 18 inches also. It expanded to .53 inches and weighted 149.7 grains.
