Maybe your mount is installed backwards?

Re: HELP! S&B 5x25 will not ZERO at 100 yards!

I am not an expert but I am almost positive that is it being caused by your ring height at 1.49". You only need the standard height 34mm Badger ring or the USMC rings which are 1". I have a 7mm/300wsm that is built on the same action and those are the rings that I am running and I have no issue getting a 100 yard zero with my S&B 5-25. I can also run the Butler Creek caps with plenty of clearance.

Hope this helps,

Oneshot

Badger rail is pinned, can only go on one way.

Not sure that ring height matters, oneshot976 could be right.

Are you sure the scope is tracking correctly? I know a fairly large batch left S&B with the wrong knobs, CW vs CCW and guys were having zeroing issues because "down" was really "up" and of course the opposite too. Was the scope new from BR, if brand new then possibly the issue wasn't discovered.

You know there is a zero stop on the scope right? If not then loosen up the allens on the elevation knob and turn the knob up to like 10 mils and retighten.

That said 4 feet is pretty high. I agree that only 1" height rings are needed for that set up but (I don't think it would throw it off that much.

Good point Rob!

Re: HELP! S&B 5x25 will not ZERO at 100 yards!

A difference in ring height will "throw you off" exactly by the amount of the difference of the ring height. All else being equal, higher rings will make you hit lower, so this is hardly the root of the problem at hand.

I'd make sure to get around the zero stop first.

Great point and definately something to be checked!

Re: HELP! S&B 5x25 will not ZERO at 100 yards!

It just about has to be the zero stop. That scope has tons of elevation adjustment. You can shoot it off a flat base at almost any range you'd care to shoot.

Re: HELP! S&B 5x25 will not ZERO at 100 yards!

i have the high rings so that my pvs-27 lines up. with the 1" rings its way off. this is what i did.

cranked in allthe way down as far as i could. then i loosened the 2 allen heads, moved the knob so it would skip the zero stop. tightened them back up, and turned it down as far as it would go again. it would not turn down any more after that.

ideas?

Re: HELP! S&B 5x25 will not ZERO at 100 yards!

Having had one with the backwards knobs, did you check to see that up is really up? That's the only thing that makes any sense. S&B will fix it in any event.

 

[Lindy]

Re: HELP! S&B 5x25 will not ZERO at 100 yards!

To check that, look through the scope while moving the knob in what you think is the "up" direction. The reticle should be moving <span style="font-style: italic">down</span>.

this one has CCW knobs on it. special order unit, is what boltripper told me. When i turn it CCW it goes up

Re: HELP! S&B 5x25 will not ZERO at 100 yards!

All I can say is wow! I am a S&B dealer wh has sold about 100 of the PM-II's and never heard of a problem like yours. Did you ask the seller if it worked fine for him? It must be the zero stop, have you called New England Custom Gun? They are the North American S&B distributor and who you would send it to for repairs or to be checked. Just ask for a RMA number if thats what it comes to. Or if you just wanted a new one I would take it in trade and swap it out for a demo or new one for not much difference. Just let me know. Good Luck

What is the MOA on your base? Badger makes a 45 MOA base designed specifically for the S&B 5-25

 

[dreever]

Re: HELP! S&B 5x25 will not ZERO at 100 yards!

This now has me thinking. I was planning on buying a S&B for om my Surgeon action with built in 20MOA rail. There's no changing the rail so will there be a problem, or is this an isolated incident?

Re: HELP! S&B 5x25 will not ZERO at 100 yards!

It depends on what S&B you're buying. The described problem means that there is either something wrong with the scope, or he's not releasing the zero stop.

The 5-25 in 0.1 milrad clicks comes with 27 milliradians or 93 MOA of elevation travel. That means, in MOA terms, 46.5 of "up" MOA. You will need about 4.5 of those MOA to establish a 100 yard zero, leaving 42.5.

Add in the 20 MOA base, and you'll be able to dial up to about 63 MOA, which is more than you will need to shoot to any distance you can get the bullet supersonic, to include shooting a .50 BMG to 2000 yards.

So, don't worry about the 5-25.

Some other S&B scopes need a 30 MOA base to reach long ranges, so it just depends on which scope you're contemplating.

Well there's your problem, it's all used up!

Really though, look at the scope mounting videos at the top of this forum. Mechanically zero your scope, remount it nice and tight, then you should have no problem. It appears you are Topped Out, not bottomed. Lower your Elevation Knob about 4'. Bag the rifle so you're 4' high, and lower the EL down to the target for a quick fix

LOL!

maybe but I must admit BT is a heck of a nice guy!

With a CCW knob, shouldn't turning the knob CCW move the ret down?

You get it figured out yet?

Re: HELP! S&B 5x25 will not ZERO at 100 yards!

There was a batch of 5-25 XRs where the "Gvendenstuch" (sp?) (elevation mechanism) was installed wrong. I had one (CCW XR). It shot 4 feet high at the bottom of travel. Contact S&B and they will fix it.

Yes it should. If it moves the reticle up, you have a problem. Right knob, wrong elevation machanism.

 

[SingleShot85]

Re: HELP! S&B 5x25 will not ZERO at 100 yards!

pretty sure it doesn't matter if its CCW or CW the scope doesn't care if you are turning CCW or CW. If up is up then down is down. As Lindy said move the dial which ever direction is indicated for up, 'if the reticle goes up as well then turret is on backwards.

I have had this happen with a 5-25-56 CCW GEN II XR.
