Ran 2 test loads today both with HP-38. Granted it was a 1 round test, but I was mostly just looking for pressure signs and making sure it cycled. this is the end of a work up so the loads are near or over max, depending on your manual. Follow your manuals.
4in barrel G19
124g XTP
4.4(hodgins max) 1041fps (hodgins says 1037 so not bad)
4.6 1018fps
4.8 (lee max) 1083 (Lee says 1088 so not bad)
115g hornady FMJ
4.7 1042 (Hornady max)
4.9 1110
5.1 (hodgins, and lee max) 1190 (stated 1135-1167, so very good)
Also fired 1 factory ammo for primer and velocity comparison
124g Fed HST 1193
I noticed a LOT of what I would consider primer cratering for all the tests, including the factory ammo. Is this common in the gen 5 glocks? only ones that looked good were the starting loads with 115. Granted it was a sample of 1 round each, but There seemed to be no significant gain from going to 4.4 to 4.8 with the 124g, so I will probably cap it at 4.4.
all columns top to bottom are low to high 124 on left, 115 on right, silver is HST
