As I mentioned, for a novice long range shooter, I feel that the above build will shoot better than I can. As a novice, I also feel that it would be somewhat foolish to purchase I high end action, stock, scope, etc. as a first gun.
Savage also use heat treated 4130 chromoly to manufacture their carbon steel actions. I would suspect their engineers, consultants, etc. would have put a lot of thought into what material to use for their target actions. If they select S.S. it must have been for a valid reason. It sure wasn't for ease of machining, as non-heat treated 4130 'machines freely', much easier than S.S.!
Again as I mentioned, IF I find I enjoy longer range precision shooting and my skills improve, either a PGW rifle, or a custom built gun using a high end action, in a McMillian or Manners stock, in a different caliber, with perhaps a S&B scope mounted would most likely be my next move.
Oh, I am like you, I highly doubt Team Savage use stock factory barrels, maybe hand selected, but I would suspect it's a custom high end barrel! I don't recall ever seeing one of their stock rifles fitted with one of those 'neat' barrel heat shields Team Savage uses!!
you are absolutely wright about this one )) we need to start somewhere and obviously, having a gun that will shoot around 1/2moa will get you to learn reading conditions at long range. I did the exact same thing so I cant disagree )) BUT....if you decide to push it to the limit, and mange to develop your skill strong enough to use 1/8moa reading (under 600 is feasable), you will try to make your grouping tighter as you will be able to use that accuracy...and that is where my passion was born...
have fun shooting, whatever material you decide to choose. Its not a contest of material but precision ! if I can be any help, feel free to contact by PM.
