Whenever I have used any Barnes, in any caliber under 30, I try to take out a shoulder, or even High shoulder or base of neck. Now, I did shoot a 80 pound shoat tight behind the shoulder with a 50gr XLC in a 221 fireball CZ 527. Right at 75 yds, made a 50 caliber hole all the way through. It dropped and kicked a bit, done. If the LRX ( that I have never used yet) are softer nose, easier opening as they claim...then I'm in love! I have some 129 LRX for my 270 and waiting on some ordered 175 LRX for the 300WM. Jazzed.
