Hold over after running out of clicks

[ctimgo]

I need 30 moa to get on target but I only have 25 moa of adjustment in the scope. Is there a way to figure out how much holdover I would need to get beyond 25 moa ? Say 25 moa on the scope and 2 mil on the reticle. I know that I can get a 20moa base but was just wondering if there was a way to do it without the 20moa base.

I might ask if you used Burris Sig Z rings with +.020 and -.010 would that be about 30 moa ?

I wanted to put 10 moa elevation in one of my scopes so I used a - .010 and a + .005 as a set in my front ring and it worked fine. With my luck it must have been a accident.

One milliradian (mil) is equal to approximately 3.6MOA. So if you have a mildot reticule and a drop chart, you should be able to figure it out from there.

You could put a .01-.02 shim under back of the scope base to allow you to have more long range adjustment.

ctimgo, is your preference hunting or competitive target shooting? IMO, "hold over" has no place in competitive target shooting except to admit that sometimes, out at 900 - 1000 yards, it may be necessary to align the horizontal cross hair up with the top edge of the target to overcome some unexpected atmospheric influence. "Hold over" is, IMO, a necessary evil for the hunter who may not be absolutely certain of the range of the target and may not have enough adjustment in the scope for some situations; depending of course on the scope. If that's your situation the list on this page may help:

If you're a target shooter, especially a competitive target shooter, I'd suggest you break the bank and get a base that will provide enough adjustment in your scope to do the job right.

I wouldn't do that with any of my scopes.

A 20 moa base is really the best way to go. Might not be what you want to hear. Besides it will center your scope better and probably give you a better sight picture. Ray

Why wouldn't you shim the base? If it's a 1 piece it shouldn't hurt it. I would do this and bed it.

Shims raise one end of the mount at the expense of leaving the other end of the mount to rest on the receiver at a slight angle at best. Of course, this can be accommodated using a filler material (JB Weld) to smooth out the transition but it's never going to be a "quality" job. If you shim the entire surface of one end of the mount to the extent that it doesn't slant toward the other end and naturally make contact, you can't tighten down the opposite end without bending the mount. If you shim one end entirely so that a gap exists over the entire area of the mounts base at the other end and use bedding material to fill up the gap you haven't changed the MOA, you've only raise the scope end to end.

Like a 6x or 8x thread pattern screw is going to "bend the mount" if a .05 shim or even several are stacked under the rear mount... Not gonna happen.

Might want to invest in a Bushnell boresighter/comparator like their model #3333 which has an internal grid that shows scope reticle movements. Grid measures 64moa on vertical and horiz. It is a great tool for all sorts of scope doping and problem diagnosis.

Yes.

Poor mans fix:

Get a cheap set of fealer gauges from auto or hardware store. Take .010" blade and cut a .500" length and slip it between the rear ring and the scope tube. Adjust by selecting thicker or thinner blades until you get it where you want it.

Just a note I find scopes are clearer and have more accurate MOA adjustments the closer they are to the center.

Example:
I have a 308 target rifle that is sighted in 52 inches high at 100 yards for 1000 yard shooting.

ctimgo: If you do decide to go with a 20 moa base, Evolution Gun Works makes very high quality bases at a reasonable cost.

My first choice is to use the Burris Signature Zee rings with the off-set inserts, .05, .010 & .020 available for 1" tubes ( you did not say what your tube diameter is), or .010 for the 30mm tubes.

I also believe in keeping my scope adjustments as close to the center of the adjustment range as possible.

Yes.

Your quote at the bottom says" Teach the Why and the How; don't just handout sandwiches"
Then you answer the mans question with "YES" and leave it at that. Everyone else is trying to help and your help is "Yes". I suppose when you call HOME and your wife answers the phone you respond by saying "YOU HOME"


Sorry guys just could not let it pass.
