If you are mostly bowling over goats, what sort of ranges are you shooting them at? What is your barrel twist? I was just thinking that instead on focusing on speed, you could just find a load that shoots well and stick with it. Will the 100 fps slower really matter?
I've done some numbers for my 16" barrel 308, compared to my 24" 308, velocity drops off more with the lighter projectiles (125gn) than it does with the heavier ones (168gn), I was trying 2208 and 2206h, both about the same performance.
For my 16.5" Bergara 308 I shoot 168gn A-max with 43gn 2206h, around 2520 fps. Same load is 195 fps faster in the 24" rifle. Either one will do the job though
