Congrats!
My XCR also made it's first kill this year, whitetail doe. Shot was about 50+ yards. The .338 RUM Ballistic Tip did it's job extremely well. Even though the size of the exit wound was incredible it still did not do as much damage as my 30.06 usually does.
The deer still ran 50 yards (at me) after being hit, spraying blood everywhere (I followed the trailer the next day).
I love this rifle so much I was thinking of getting another in a lighter caliber.
