al4x Posted December 22, 2010 Report Share Posted December 22, 2010 (edited) Got an issue with a new scope I'm trying to Zero, its on a remi 700 with bases that are an unknown make. It used to have a 1" scope in Leupold standard rings with no issues, got 30mm high rings today and I just can't get enough elevation on the scope the most I can get it to is 2" low at 100 yards. Obviously these only fit one way round but is there anything else obvious it could be? Edited December 22, 2010 by al4x Quote Link to comment Share on other sites More sharing options...
Redgum Posted December 22, 2010 Report Share Posted December 22, 2010 I have leupold mediums on my Rem 700 243, great mounts and give just enough hieght for 44mm Objective. You say that these are an unknown make, are you sure that both mounts are the same height, I remember a mate had some sportsmatch on his .22lr and he was stuggling, he had medium on the front with some highs on the back.

Dekers Posted December 22, 2010 Report Share Posted December 22, 2010 (edited) Well, I know its stating the obvious but the mounts are mismatched/faulty or the scope is, there isn't much else it can be if it was ok with your previous scope/mounts!

Paddy Galore! Posted December 22, 2010 Report Share Posted December 22, 2010 What about the bases, are they the same thickness? not sure about your remi but on my win70, the rear is thinner than the front base, could this be the problem?

seeker Posted December 22, 2010 Report Share Posted December 22, 2010 A Howa uses the same bases as the Rem 700... and the thicker one goes to the rear ... is it possible they're the wrong way round, or bothe the same height ...and the 1" rings are different heights to make up the difference??

al4x Posted December 22, 2010 Author Report Share Posted December 22, 2010 Its very strange the bases haven't been changed and aren't the wrong way round as you can't fit them wrongly. Having had it all apart both rings are the same height as were the old ones the only difference between the new and the old ones are that the new ones are about 3mm lower. The scope really should be fine came from a known source so I can be as sure as possible it was fine when sold and is a decent swarovski so the mystery continues. Short of shimming it I'm at a bit of a loss but on a 6-24 I shouldn't need to, I guess more playing is required as I lost the light this afternoon. Still a pain in the backside when all you want to do is use a new scope Quote Link to comment Share on other sites More sharing options...
Rasher Posted December 22, 2010 Report Share Posted December 22, 2010 My guess would be that there's a few thou difference between the new mounts. You say you measured them but what with? Try swapping them around and see if the problem repeats itself. You might find the rings need some lapping in done. You say the scope can from a known source, but is it 2nd hand? If its 2nd hand is the tube straight? Quote Link to comment Share on other sites More sharing options...

I would hope so with it being a moderator on here its a mint condition scope no signs of bangs etc you can't swap the rings round as they only fit one way, Simple question is could these being slightly higher than the last ones make that much difference? otherwise I've two options try it on the rimmy with the rings it came with and if thats fine then shim it to get it working as its only for a few weeks till I get a .243 for it to go on. And that is why its rather annoying though on second thoughts looks like you may be able to adjust the turrets to set the elevation so I guess its possible this has been done in the past to suit a different set up http://www.swarovskioptik.com/upload/media/media/26/ba_habicht_p_9spr[1305].pdf Edited December 23, 2010 by al4x Quote Link to comment Share on other sites More sharing options...

al4x Posted December 23, 2010 Author Report Share Posted December 23, 2010 there has to be a simple answer but I'm ****** if I can work it out I mean its not like its a scope with a small amount of adjustment. And it was fine with the S&B before Quote Link to comment Share on other sites More sharing options...

By swap I mean move front to rear and rear to front. "Simple question is could these being slightly higher than the last ones make that much difference?" Simple answer, yes! It is possible if it has the drop and click adjustment turrets. Ask the guy you purchased it from. I always make sure that the reticle is centred for both elevation and windage before fitting a scope. That way you have something to index and work back from. Good luck!

al4x Posted December 23, 2010 Author Report Share Posted December 23, 2010 you did make yourself clear but I possibly didn't if you look at the bottom of the rings you can't mix them front to back I'll have a word with the seller but as he's moving house today i'll leave it a little while Quote Link to comment Share on other sites More sharing options...
al4x Posted December 23, 2010 Author Report Share Posted December 23, 2010 And is it up for sale? the S&B went last night and I almost said I didn't want to sell it as now I only have the HMR for foxing in the snow till i sort it Quote Link to comment Share on other sites More sharing options...

I suspect your suspicions that the scope's been re centred by the previous owner is where your problem lies. Re-index the reticle and then see where you're at after that. Personally I don't like to have a scope fitted on a rifle that has to be on the extreme end of its adjustments in order to get it zeroed. Regardless of how good a quality of scope, and would rather swap out rings and bases in order to over come the problem. I can fully understand your frustrations.

al4x Posted December 23, 2010 Author Report Share Posted December 23, 2010 If I can re centre the scope then I'll be happy just seems really odd, out of interest I could go onto lower mounts would that improve the lack of elevation or not. I'm having trouble getting my head round it at the moment. If I had to take a guess the mounts it came with are higher than mine so possibly this is an answer. I'm fairly convinced its something simple its just a case of what Quote Link to comment Share on other sites More sharing options...

I'm fairly convinced its something simple its just a case of what Putting on lower mounts will only increase the problem, as you say in you OP that you're already 2" low at max adjustment. You might find at the end of the day that you'll need to shim the front mount. Quote Link to comment Share on other sites More sharing options...
al4x Posted December 23, 2010 Author Report Share Posted December 23, 2010 shimming the front will make it worse though however the rear effectively tilts it down so in theory will improve it, takes a bit of getting your head round when you have problems Quote Link to comment Share on other sites More sharing options...

al4x Posted December 28, 2010 Author Report Share Posted December 28, 2010 yup shimmed it and it now shoots a treat, I would look into it more but its only to keep it shooting for a few more weeks till I can afford a new sako and then the scope will go on that. The S&B always shot really well and have to say I only ever checked zero I can't remember it ever changing unless I swapped ammo type so glad to hear its working nicely on the hummer Quote Link to comment Share on other sites More sharing options...
