I had a box of hornadys 155 gr. XHP and used the hodgden web site for this load. Winchester 231, 5.0 grs in a glock 22 just yesterday and was comparing these reloads to some factory Federal 180 sp. All reloads functioned fine except the glock didn't eject the brass as well as the factory loads. I was working on some reloads for light practice target loads, also used Unique 5.5 grs with no problems and planning on some more Unique loads for reloads.
