I highly doubt its a true "1/2 moa" rifle, even at 100. Those, as we all know, are hard to come by.
I agree. Never said it was a 1/2" rifle and it's suspect at best right now....
The title of your thread says "why would a rifle shoot 1/2 moa at 100 yards and 2 moa at 200 yards". I didnt say it was a "1/2" rifle" either. There is a difference. If you want help, you need to know and understand the difference. I also think its a parallax issue, as i have lost all faith in leupold rifle scopes. Ive seen so many go tits up, it isn't even funny. Vortex is in the same boat. When evaluating the accuracy potential of a rifle, one of the general rules (for myself) is to start with a "proven" rifle scope and mounting system. If you buy a rifle that already has bases and rings attached, pull them. I make damn sure everything is de-greased and ill go through the extra bit and chase/clean up the tapped holes in the receiver, check screws for proper length (to be sure they arent going to bottom out prematurely), use blue loctite and make sure everything is tight and perfectly lined up. As ive said before, out of alignment rings puts uneven pressure on the scope tube, which may allow the scope to move during recoil. What some dont realize is, if the scope twists or moves, just a minuscule amount, it will have a profound affect on accuracy. If you dont believe me, do a little test with said rifle: Get it all zeroed, then pull the scope off, tighten it back up and see where your poi shifts. It may be an eye opener. Thats why it may be necessary to lap your rings and in some extreme cases, even bed your bases. Furthermore, Im not saying its a bad shooter or bad rifle, but you need to make sure your bases are well covered and your foundation established, before pulling the trigger, if you are in search consistent accuracy in a rifle. Jb has been hitting the nail on the head, you may want to pick up some of his books or search out articles regarding accuracy enhancements, rifle accurizing etc. I havent bought a magazine in over a decade, but i know accurizing tips and tricks were always a hot item, discussed by JB's buddies in rifleshooter.
