Q & A: Why does DSXP have a polymer tip?
Interestingly, polymer tips do a couple of things very well for hunters. Number 1, they make a bullet incredibly streamlined so it will travel true; and maintain its downrange energy – this then gives the bullet a very high ballistics coefficient. Next and unique to Winchester, the polymer tip used on Deer Season XP is much larger than other polymer tips you will find in the market place. This leads to incredibly rapid expansion at impact. Needless to say, bigger tip – bigger impact.
