Re: scope receiver holes not square

JMB ballistics ask for sight offset. This criteria for calculating drops and windage is where I might get into trouble on long shots . How much does sight offset affect
these calculations?

It's a small but measurable effect. Sight offset usually comes from the rings, but base misalignment and barrel misalignment can also be a factor. For most rifle set ups, the offset is less than 0.1", but can be larger if the reticle is not aligned properly. Play with the JBM calculator to determine the magnitude of the offset.

Using the Reticle Alignment Tool from HighPowerOptics will eliminate this error.

Re: scope receiver holes not square

I received my sign. Zee rings and after re mounting the scope about seven times with no improvement measured the -10 and +10 inserts. They all measured the same. Burris is sending me new ones. Burris needs to take the inspection sticker off of their packages!

Does anyone know torque specs on these?

Is there supposed to be a space between bottom of ringbase and top of weaver base? I do not like air between my base and rings.

That astonishing. The offset inserts are injection-molded plastic. Maybe they had new molds made. Where on the insert did you measure the thickness? It should be measured in the middle, next to the +10 or -10.

Yes, the Zee rings grab the edge of the rail. I haven't had any problems with that design.

Yes next to the#. Measured with analog and digital calipers and then with my micrometer. Did a search and found others with same problem. When I called the lady didn't sound surprised. She didnt ask me any questions and was really quick to apologies and sounded as if she had replacements right beside her.

Re: scope receiver holes not square

Beside the point Bruce I noticed you sell Bushnell 6500 elite 4.5-30. That is my favorite scope next to my NF. I was very very tempted to buy another one for the savage111 but the receiver is so looong it seemed the vortex would fit better. The 6500 has a smaller mounting length and fit a LA 700 better. So it stays on my Sendero.
