rotating a rifle scope

Post by bigrich » 29 Oct 2021, 9:02 pm

hey fellas , got a technical question for ya's . now i've got a sako 85 , and although it ejects successfully with a 3.5-10 leupold , with a 2.5-8 it does not . even with the 3-10 the 270 cases contact the bottom of the scope , but with the 2-8 they hit the turret and fall back in the chamber . i've read up on the fixes, and i came across one on africa hunting net . turn the scope 90 degrees to the left . no turrets in the way . you have to write down the changes to make adjustments to save confusion . i've already tried this and no ejection issues at all . but my local GS guy reckons they won't hold zero . but apparently this turning to the scope left thing is used by left handed shooters and big game hunters in africa and alaska .

any thoughts, veiws or experience with this :unknown:

Forget the gs bloke and just do it if it works good .
Just remember windage is elevation and elevation is windage

Put the 3.5-10 leupold on and post the
2.5-8 to me. See problem fixed. :D

Always happy to give great advice. :drinks:

While I've never tried it and have less experience with scopes than you do, I reckon the gun shop guy is full of it. Just thinking about the physics of it, if it wouldnt hold zero from doing that then how is the scope ever going to handle recoil from various rifles, lay sideways in a car while going over bumpy dirt roads etc. It would have to be stored and shipped upright at all times etc. Their scopes are better than that.

Have a look at how they set up the adjustment of reticle tube and you'll see that gravity doesn't come into it. It's basically springs opposing the turrets

It would also mean you could never shoot your rifle "gangsta" style-hold your rifle sideways when hunting so you look cool in tv shows and to all your friends, while trying to intimidate the deer or goat you want to shoot. Leupold would never want to piss off their large hunting gangster customer base (yes, this is all tongue in cheek if it isn't obvious)

yeah , that's what i thought . i'm just looking for feedback from fellas who have done this , just to find out if there are any negatives to going down this path . once i'm zeroed in , i don't play with the turrets . i set up to be 2.5" high at 100 yards with 270, that'll cover me for the hunting ranges i shoot at :thumbsup:

Have you considered a left handed scope? Or maybe turning it back to front :D

no , but i've considered trading my sako 85 for a earlier L61 finnbear . they eject straight out the side and i won't have to rotate the scope ...... ;)

Yep, works just fine. Some long-range scopes might have limited windage, meaning limited elevation when you turn it 90-degrees. You might have to do some shimming in that case but I think you'll be fine, and it doesn't hurt to try it.

Might be either too simple or too silly or successful,,,,,,
but have you considered trying a "higher" set of rings, and maybe avoiding the impact of the casings ?

cases eject at around 75 degrees out of my rifle . i'd need a neck like a giraffe to shoot it with high enough mounts . i've researched the problem extensively . i'll have to take my sako 85's to a smith to try a combination of extractor mods, and a heavier extractor spring seems to help as well . they moved the ejector from the side like mausers, mod 70's , ruger 77's, and put it at the bottom of the action to allow for the three lug bolt introduced in the sako 75's . earlier sako's from the "A" series back have their ejectors in the left side of the receiver like a mauser, and reliably eject every time straight out the side of the action

i've sort of solved the problem however, i bought a L61R finnbear from rebel gun works yesterday in 30-06 . :D was built up by their gun smith with a really nice custom stock . i got a few finishing touches planned , but it solves my problem :lol: scroll down rebel's home page to have a look. if i can't solve ejection issues my 85's are going . well , i'll probably keep the 9.3x62 with express sights . i was going to use that with opens in big game comps at my local club :P

depends what your going for . as a all rounder i use 150 sst with 55.5 gn re22 . average shoots 3/4" at 100 . 150 sst's expand well on lighter stuff with enough weight for heavier stuff . they can cause a lot of damage with larger body weight, more resistance for expansion . 140 nosler bt's for lighter stuff, with bonded accubonds if you were going to shoot boar or reds . i like 270's :D

haven't gotten around to trying 2209 , cause re22 works so well . got a bit left from playing around with swedes . i've also gotten outstanding accuracy in 243's shooting 95 gn projectiles with re22 as well it can burn dirty like 2206h does in other rifles but :thumbsup:

I've done it before and it works doesn't matter what's written on the adjuster knobs. Obviously the one at the top adjusts up and down and the one on the side adjusts left and right...

so there hasn't been any quirks or shifting point of zero with doing this ND ? that's good news :D

obviously you'll need to sight it in. I cant see how it would loose zero if it didn't before might look a bit weird if its got the dots on the vertical crosshair tho and you turn it 90deg

You will definitely have to re-zero.

I did this with my M70 Winchester, to make absolutely sure of loading the magazine in a hurry. Did not even try it in the conventional position, so could have been overly pessimistic. However, once it is re-zeroed, you can forget about it. It will stay put.
