Lilly, Remington makes a synthetic stock 700, you can get the gun in either 223 ,22-250 or 308. They have the full size Polcie sniper model or Varmit model..I believe they also make a short barrel version, which I feel would be ideal for you. As fa r as caliber, obvioulsy 223 or 22-250 are easier on the shoulder, but the bullet will be affected more by the elements. Remington guns are priced right and are relieble. Remember, when you mention the words sniper and rifle together, you are generally speaking of a heavy barrel, and a thicker stock, which equates to greater weight. Also, look at Gunsite (Jeff Copper) scout rifle.
