Hello. This is my first post and I just got my first F class rifle in 6.5x284 Norma. I used a lot of the information I found on these forums to help me make the decisions on my setup so thank you.
I loaded 33 rounds to start off with. 3 rounds each going from 45 grns to 50 grns in .5 grn increments H4831. I'm shooting a 140 grn Speer spitzer hot-cor.
My problems come from not being able to find H4831 data for this caliber except in the shortcut form (h4831sc). From what I could find the data for these should be interchangeable with negligible differences in burn rate. Is that truly the case?
My Nosler reloading data says min-max of h4831sc is 45/50 grns. They also list a COAL of 2.980. I like to go a little further than what is generally listed so I went for 3.020. I was fine until i started reading posts on forums and I didn't see anyone seating further than an OAL of 3.1. I was worried then that i was seating too far and might be causing excess pressure. I became even more paranoid with the h4831/h4831sc discrepancy.
So in short, I guess i am asking if the below load load is a safe starting point for load development since data is limited.
Bullet: 140 grain Speer spitzer hot-cor
Powder: H4831 45-50 grain
COAL: 3.020"
CCI 200 primers
Thanks in advance
