I also have used Xtreme for a long time with zero issues. They make a good product that is very consistent bullet to bullet. Many have stayed away from Xtreme because the price was nearly comparable to HP's. You need to find out if plated are accurate in your gun. As far as OAL goes, please do the plunk test in your barrel to find the optimal length. You also need to take into OAL consideration if that length will feed from your particular magazines. Hope you have the same success I have had with Xtreme's.
