WW Power-Points, the early ones anyways were always quite deadly and very accurate. As to expansion of various rounds, it may sound counter intuitive, but I would expect Subsonic HPs - the CCI to open downrange, due to it's cavity depth and volume. That likely applies to others - I believe one or two from overseas like RWS may also be similar. Not sure how they would kill at long range, as they start out slower, though will have less ballistic lag because of it, so shed speed slower.
Yellow Jackets were my choice back in college in a 4" M17 - it was deadly on various critters out to near 100 yards, how much was the bullet used vs placement, I cannot say. It did put things down quick.
In rifles, I noticed a difference in WW PPs vs CCI Mini-Mag HPs. PPs being more lethal downrange. No experience....yet with Velocitors.
