I have recently changed my carry from a j frame to a m&p 9mm. Now I need to get me some hollowpoints for it. While perusing the internet I keep reading how a lot of people recommend shooting at least 100 rounds of the selected ammo first to ensure it functions, is accurate.... etc. I don't have that kind of money. I am considering buying a pack of xtp j words and just loading them to approximately the same velocity and calling that good enough. What are you guys thoughts on that? I will be using factory loaded ammo for carry. I honestly have just shot a few to check function and called it good in the past.
