Looks like you are off to a good start!! My only thought or response will be....RL17 was super temp sensative when I tried it. If you are going to use that rifle in colder weather, I would not be relying on what you find at the range in 80-90 degree weather. I sold all my RL17 for that reason. I use H4350 with great results out of my savage stealth 6.5 .
