I would agree with Ihatepickles that the OAL you are using sounds long for the XDm 5.25. I use Precision Moly 147g and have been using an OAL of 1.12. However, I see you are using Hornady XTP JHP's so the ogive may well be different and will let you use a longer OAL. Just give it the barrel check Ihatepickles describes above and see if the ammo passes.
