mirage243, running light weight bullets at high speed is fun & can be very accurate with minimal recoil & if the target is just small game or random targets the impact can be very impressive.. But one thing I might mention is the use of light cast HP's at high speed on deer, etc. They could easily fail even on small deer if pushed to high velocity. The only bullet I would use that is light weight is the 170 gr Sierra which is designed for doing just what you mentioned.
Lots of game has been taken with that bullet at high speed with no problems but a light weight cast HP could prove to be a real problem, just my opinion. Either raising the bullet weight a bit or slowing down that 175 HP a bit might serve you best on small white tails.
