Re: Bore Sighting & observations

Dave,
Another real obvious thought that crossed my mind last night.... is a bent barrel. Ask any of the good smiths how many perfectly straight barrels they have even seen? My current 1000yd BR LG barrel had 4.5 thousands of runout in it. This is not uncommon from what I've seen.
I also know of a barrel from a very prominent maker that had more than .010" of runout in in right out of the box. The shooter did his own work and physically tried to striaghten it the best he could in the lathe with another large bar for leverage. The same barrel cleaned my clock at the last NC match of the season. It will shoot!

It wouldn't take much to cause a 2-3 MOA offest at any distance. I know if your front and rear rests are 24" apart, moving your rear rest .0006" in any direction will move your POI 1" in the oppssite direction at 1000yds. So at 100yds that would be .006" of movement would equal the same 1" of movement. Translate that to a 24" barrel with .006 of runout, and you might have an answer to your "problem".

Or like Aussie said... if your happy with the accuracy of the rifle as it sits right now... I would go with the beer or 12 option also. Brand doeasn't matter after the 6th one anyway... though Yeungling is my personal favorite.

Steve

Re: Bore Sighting & observations

Just a thought dave. Have someone else shoot your rifle without telling them why. If they shoot where the bbl seems to be pointing as opposed to where the scope is looking then the problem may be you. Maybe the stock dosent fit right or you are bracing after the sear breaks or some other quirk you have with this gun causing you to pull the shot left albeit a very consistant pull. With enough practice even a flinck can be consistant. Thats one reason why we own adjustable sights.

Re: Bore Sighting & observations

Several goods suggestions here but I believe Steve is probably correct in one or more of his suppositions.

I have a pile of rifles and this one is the only one that points somewhere other than at the target as far as the vertical plane is concerned.


Oops, Aussie too, he's correct... beer works.

Re: Bore Sighting & observations

Dave,
You need to get you mind off this little situation - the only logical thing to do is to get on the phone and order another rifle [img]images/icons/tongue.gif[/img]
Believe we need to discuss your upcoming new tactical style rifle that you don't know about yet...

Your new tactical rifle will have to be built such that it will be able to take full avantage of your new ultra reliable user-modifyable scope that you created. That way it should be able shoot 2000 yards easily! [img]images/icons/grin.gif[/img]

Re: Bore Sighting & observations

Dave ,
So long since I was in the U.S. I can't remember for certain which beers I liked (I think it was the cold ones) . No matter , I'm sure they all have the same medicinal properties .
If that doesn't work you gotta get rid of that gun and replace it with 3 others . [img]images/icons/smile.gif[/img]
