Recently I bought a box of 130 grain Winchester Supreme Elite XP3 for my 270 WSM, intending to hunt cow elk with them, this fall.
They were "only" $47.98 for the box of 20, and I was glad to get them at that price, which was about $10.00 cheaper than I had seen them for.
But, when I got home with them, I noticed the statement on the back of the box that they were, "designed for massive knockdown on deer sized game".
Oooops!
I bought them while traveling in Mississippi, and read the disclaimer when I got back home to Texas - so no taking them back to the store for refund.
But, after reading about the construction of the bullet (complete with a cross section drawing of both before and after configuration) on the back of the box, I think they will do the job on cow elk.
Especially convincing, to me, was the illustration on the back of the box showing the details of "2-stage expansion" (TM). The claimed end result of said 2-stage expansion is a mushroom of copper "petals" (similair to a Barnes X-bullet), with an expanded diameter shank immediately behind the petals, with the presumption (on my part) of almost 100 % weight retention.
The only advantage I can think of that the 150 grain version would offer over the 130 grain version is a slightly slower opening of the "petals", and 20 grains more retained weight.
On the other hand, the 130 is about 150 fps faster muzzle velocity, which flattens the trajectory a little, beyond 300 yards (less than 300 yards, the trajectories are within an inch of each other).
So, what do you think guys/gals - do I need to go buy the 150 grainer, and use the 130's on deer (overkill!!)?
