Let me ask you a few questions to give you some things to think about. You said hunting out to 600 and target to 1000 yards. Have you shot these distances before on a regular basis? What will you be hunting and where out west? Mountains, plains, what elevation, etc... The reason I ask is I had my second elk hunt, first guided, this past October. I used a custom McWhorter 270 Weatherby with 165 gr Matrix bullet with a Night Force 5.5x22x50 NXS scope total weight 10 pounds. Never did a lot of long distance shooting before but wanted to so like you, I wanted a rig which would enable me to play a little. Let me tell you a 10 pound rifle is one heavy SOB at 11000 feet after a couple of miles. Especially when you live at sea level and are gasping for breath at that elevation. I target practiced out to 750 yards and it was totally different between 500 and 750 yards. Now when I got into the mountains with winds at that elevation not to mention ridges and valleys that play Hell with trying to figure all this out for shot placement... I will be selling that McWhorter, just haven't taken the time to put it up here yet, and am working on a 300 win mag right now. I am going with a cheap Tikka SS, changing the stock to a McMillan Hunter, and putting a Swarovski Z3 4x12x50 ballistic turret on top. This scope does not have the parallax adjustment on it and the whole rig should be around 8 pounds. Will sight it in between 250 to 275 yards so I will be good to about 350 without having to make any elevation adjustments. I learned the hard way that when things happen on an elk hunt they happen quick. Unless you live in an area like that and have the time to practice practice practice, you've got no business taking a shot under those conditions. No, I did not, and yes I got an elk but, we rounded a corner and there he was. I had just enough time to bring up my rifle, hold my breath, while turning blue, and shoot. It was over that quick. I would not have had time for much else much less range, adjust elevation, adjust parallax, etc... I was just glad it wasn't much over 200 yards. For me personally, I don't shoot enough for the custom rifle that I have, lesson learned. Not trying to burst your bubble, just giving you things to think about from my experience.
