Re: 100yd or 200yd zero?

Ok here we go. I just got back from breaking in the 5r and think she gotta chance! I just had one problem, the gun is shooting about 8inches too high and 4inches too far right and I'm out of adjustment in both directions. What to do?

Re: 100yd or 200yd zero?

That is very disturbing........something is fundamentially wrong if that is the case. Shooting 8 inches high and 4 inches to the right and your scope is out of adjustments? The groop looks good but that is very concerning.


Question: Why load testing at 200 yards? I have always done them over the chronograph at 100 and the loads/groups have always turned out well.

As for the zero, if it is a hunting gun then the 200 yard zero should be perfect. If it is not, then you will be dialing for everything anyway and I would zero it for 100(as is my practice and will always be).

Re: 100yd or 200yd zero?

Shot in the dark here but could the scope have shims installed for a zero stop?? I know that the Vortex system for zero stop requires shimming the turrets to get them to return to zero. I wonder if yours is shimmed to the point that you cannot get to your "zero". Just an idea. I am currently running a 4x16-50 HS and love it. I am purchasing a 6x24-50 PST FFP very soon. Good luck and keep us posted.

Do the adjustments need to be in a certain place prior to mounting? It is a practice gun and not a hunting gun. This group was at a 100yds after a good cleaning with boretech.

I dont think so. I took the cap off and didnt see any shims. From the outside the shows to be all the way down to the 1st revolution mark. Plus all the shims are still in the box.

Re: 100yd or 200yd zero?

I had a similar problem. Easily a 5 shot 1/2 MOA group on a new gun but ran out of windage on a 30mm tube. ? What the heck. I put the gun in a vise, removed the bolt, adjusted the vise to where the crosshair was centered on the shot group. Made sure I didn't bump the vise and stood about a foot behing the butt and looked down the barrel. ? again what the heck. The end of the muzzle wasn't even pointing on the target, anywhere. This was at 100 yards with a 20" square target. Turned out the barrel was warped the last few inches, severe enough for a 24 MOA difference. Try this method. If you have a straight barrel when you look down the muzzle with the scope centered on your shot group it should be alligned a few inches above your group. You may have a warped barrel if not. In my case the manufacture replaced the barrel at no cost.

Re: 100yd or 200yd zero?

I couldn't zero @ 100 yards until now. I had a 20MOA base on my 5R and my scope ran out of elevation adjustment. So, I receny put a 0 MOA base on it for shooting my heavies. It's still topped out, but I should actually be able to zero it out now with my 210 Berger load. And that means I still have 45 MOA of downward adjustment to shoot at distance. Apparantly with my setup I won't need the 20 MOA base. And I need 65 MOA of elevation adjustment I don't need to be shooting a .308 at it. LOL
