I'm happy. I knew I wouldn't see the huge gains with the ah because of case capacity and short for me barrel. I had the 169's HH over 3150 with n570 which seems to be my favorite powder but I ended up going down due to stability factors at my new home .That's moving right along! I was happy with my 24" 280 AI with that bullet at 3160 FPS. It too may speed up as it's only got a few rounds down the barrel.
