140's and 150's? Nothing wrong with any of them.....I started out using 130's..things died.Then,later bullets got better,and if I shoot a 130 that keeps 90-95% of its' weight,expands and makes it to the off side hide,I figured how is that not as good, or better,than a 140 or 150 that loses 1/3 to over 1/2 of its' weight (integrity)?
By just switching to a tougher 130,I get the same effect(perceived benefit)of a heavier bullet,and I'm spared the mental anguish of wondering which is better.
Sometimes, it isn't what you start out with,but what you end up with........
