When I was shooting my XDM 5.25 in comps it ate everything I ever fed it, not picky at all so Im sure the MG 147gr FP bullets will feed just fine. When I shot 147gr ammo it was coated lead and with titegroup I think 3.1 was the sweet spot for accuracy and velocity out of my gun.
If you didn't know, Hodgdon has a great online resource for their load data, they are showing a 147gr XTP load starting at 3.2gr and maxing out at 3.6gr of titegroup at a 1.1 OAL. The 5.25" barrel helps getting the velocity up, I would think 3.3-3.4 range should put you in a good place. As always, start low and work up with a chrono. Good luck.
