Can someone with a Hornady loading manual help me out?
I need to verify the start load for the 300gr XTP/Mag in .454 Casull.
My information (from Alliant) say the start load is 25.4gr of 2400.
Thanks in advance.
Last year for hunting season I loaded the start load and got 1600fps from a Ruger SRH 9.5" The primers (WSR) were fairly flat, and extraction was a bit sticky. Due to the sticky extraction I vowed that this load would not be increased.
This year I loaded the same load, with the same box of 100 primers, and the same pound of 2400 with 25.4gr of 2400.
The chrony gave me a bit more velocity this time (1625fps) but this time I am seeing a hint of cratering on the primers (the metal of the primer flowing into the firing pin hole).
