I am trying my hand at handloading 180 gr .357 HP-XTPs for a hog hunt this weekend. I can't seem to find much loading data for 180 gr. jacketed bullets. The max H-110 180 gr. loads from major sources are:
14.5 gr - Lyman Manual (JTC SIL XTP) 1101 fps 1.585 COL
13.1 gr - Hornady Manual (HP-XTP/JTC SIL XTP) 1050 fps 1.590 COL
13.5 - Hodgdon Manual (Nosler Partition) 1396 fps 1.575 COL
This is quite a variance! I want to get a near max load out of my 6" GP100 (1200-1250 fps) but don't know where to start.
Confused. Please help.
