Re: .308 velocity and load question
My guess is that you are between 2700-2800 FPS.
I was using this same load for a while and believe I was getting around over 2700 (if my memory serves me right) and this was with 24" pipe.
I know that 2700-2800 is a big difference but without a chrony, it is hard to guess.
If you use 2750 as a staring point for a ballistic calculator this will get you very close to start. My suggestion is dial it at 300 yards and move out to 600 and compensate according to your calculator based on 2750 and a .450 BC. This will get you scary close.
46.0 of VARGET is a pretty safe load in a factory rifle. If there are no extraction issues and the brass and primers look good, youre most likely not pushing them too hard.
Hope that helps!
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
