Jwp were both of those shot into the ground? I have shot the 175 in 41 mag and they expanded well with some fragmenting. The problem with the silvertips is with penetration because they are light for caliber loads. They would kill a deer fine but you may have a tough tracking job with no exit wound. If that's all I had I would use them in the morning or in an area where I would likely be able to see the deer go down.
