I'm picking up a sig P239 this week and I realize ammo isn't the cheapest. There seems to be a certain amount of concern when it comes to reloading this round. Could those of you who have experience with this round please wiegh in with your perspective. The good, the bad, the common pitfalls - please share. I've loaded the 45acp, 45 colt, 454, 416 taylor, 357 mag and 22k hornet to date. Thanks, bt
