I have just started reloading 308 for my bolt action, and need some help with how to find my most accurate load for my rifle.
I started my loads using Hornady 9th edition data, Hornady 150gr SST, IMR 4064 powder. I loaded up the first 4 charges as listed by Hornady , just to start low and check for pressure signs as I went up. I was looking for the best group and then planned on working in small increments.
38.4 (2300fps)
40.4 (2400fps)
41.7 (2500fps)
43.3 (2600fps)
100yds
Is it odd that the 38.4 has the best group and is super tight?
The other 3 loads were not even close in group size.
Starting with the 38.4 gr just seems so low to me?
I guess I am getting to hung up on high velocity
