Nikon elevation issues

[spudgun]

Ok, I have a Nikon M-223 mounted on my AR 15. Sighting in at 100 yds I need to crank the elevation up to 200 YDs to get on paper. There is no way to reset my turret back down to the 100 yd mark without effecting the elevation. I think I have found a solution by replacing my catileaver mount with a Nikon M223XR mount. The XR style has a 20 MOA slant which would allow me to sight it in at 100 yds and still be at the 100 YD mark on the scope. Anyone confirm this will solve my problem. Picture shows my elevation turret sitting at the 200 yd mark.

I thought those were spring loaded reset?

You can't remove the screw on the top either and turn the turret to be zero at 200???

Never seen a target style turret that couldn't be removed.....

Yes they are spring loaded turrets, but I can only rotate 1 turn to zero that range. Say if the turret was at 235 I could rotate back to 200 but not go down to the 100 yd hash mark (horiz line).

OK now I'm a little confused. How are you correlating the horizontal revolution indicator lines on the turret with yardages?

Ok, the way I read this scope it is calibrated for the .223 at 3200 FPs, 55GR FMJ. The instructions that came with this scope really suck and so does Nikons website. I have confirmed with Nikon tech dept that the cap is calibrated in YDS for .223 only The reticle is Nikoplex, in other words that is only 1 cross hair the main ones. No BDC marks under it. It is not a big deal that the horiz line is 200 and not 100 as if I want to shoot 200, 300 yds or more I just rotate the turret to the yds that I want to shoot.

My first question was will a 20 MOA slope allow me to get the turret back to 100. I have also noticed that the older Nikon P-223 scope mount is being replaced with the Nikon P223XR (XR, xetreme range) with a 20 MOA slant which in theory should allow me to take the turret back down towards the 100 hash mark on the scope. I guess since this is a new product (the mount) not too many people have tried it. I do know that 20 MOA mounts have been on the market for awhile and I have never noticed them or payed attention to them as I never had this type of scope before.

I believe the horizontal marks are just the number of turns for reference from the bottom. Like most other scopes. So, if you crank up several revolutions, you know where to crank back down to for your original zero.

You could be correct on that.

Since the turret is marked from 100 to 600 yds in less that 1 turn. Like I stated the instructions that came with this scope were useless and so was Nikons website. Found nothing on Youtube about sighting in this scope with the Nikoplex reticle.

Kinda gotta guess about the horiz line settings. The turret is clearly marked for 100 to 600 yds.

Was hoping someone here had this scope and already figured it out.

I was asking about the new P223XR mount with 20 MOA slant, but it just came into the market this year. Maybe I'll buy one and try it out and report back (when the weather warms up).

Thanks all for your help...

Ok, so you ARE thinking that the horizontal turret lines equate to yardages. That is completely wrong. No turret on any scope marks yardages on the horizontal lines. Those are strictly for letting you know which revoultion of the turret you are on. Used for returning to zero like Paul stated. The horizontal lines have nothing to do with yardages. #1 horizntal line does NOT mean 100 yards, #2 horizontal line does NOT mean 200 yards, etc...The vertical 100 to 600 yard you see on the single revolution of the turret are your yardage dialing markings.

There are situations with certain turret designs when shooting extreme long range where you need to look at the horizontal lines to know which revolution you are on to correlate with which vertical turret yardage marking you are utilizing. But I don't want to confuse you too much until you understand that the horizontal lines are only for counting turret revolutions.

I agree with you. After thinking about it for some time it didn't make sense that it would be yardage as the turret will go from 100 yds to 600 yds in less than a turn.
My concern at that time was running out of up elevation clicks on the scope. I have had some situations that I just didn't have enough up or down clicks left in the scope to get it sighted in at 100 yds. (cheaper scopes too)

 

[Ledd Slinger]

Yeah I never buy "calibrated" turret scopes. The yardage markings never match up perfectly. I suppose a person could fight to find a load that matched up with them, but that's the last thing I want to be concerned with. I load for the speed and accuracy I desire, test at long range to acquire "actual" drop values, then mark my turrets accordingly or make a personalized drop chart for quick reference and tape it to the inside of the rear scope cap lid.

 

[spudgun]

Well this is the first one I bought with a calibrated turret. Working in gun counter at Cabela's and it went on sale for $199.99. I bought it right on the spot, also got a Leupold Mark 4, 6.5-20x50mm LR/T M1, for $399.99. Was a good day for me and I spent my paycheck for the week.

Nikon's Rapid Action Turret is calibrated for .223/5.56 55 gr bullet at 3240 fps. Zero the rifle at 100 yards, lift the turret and turn to 100 yards and you are good to go. I have used one to shoot steel plates to 500 yards. Nikon doesn't make the Rapid Action Turret scope's any more but a Custom Turret can be ordered. I have a few of them on deer rifles and they are very accurate. As with any Custom turret the result's you get are only as good as the data you input. You can use Nikon's Spot On Ballistic Program to get accurate shooting data if you decide you want to dial in your distances or you are using a BDC reticle scope.

Nikon's Rapid Action Turret is calibrated for .223/5.56 55 gr bullet at 3240 fps.

As bullet drop at different ranges decreases with altitude, what altitude above sea level are Nikon's bullet drop compensation settings (Rapid Action Turret) calculated for?

 

[dmoran]

My "bullet drop compensation" out to 500yds is hold-off from a 300yd Zero. Aiming a few inches high or low based off field testing, is my way. I use 100yd Zero's for 22LR, muzzle-loaders, and come-up dope for centerfires.

Nikon's Custom turret is set to whatever elevation,temp and humidity you choose. Very versatile and easy to own more then one turret for hunting vastly different area's. Just go to Nikon's Spot On program and click the Custom Turret button to see all the info you need to fill out to get the most accuracy for your hunting needs. Again, you can get 2, swap them out depending on where you are hunting. Mine are all dialed in to what I would experience while deer hunting in TX/OK/KS.

I also routinely utilize Nikon's Spot On Ballistic Program for my BDC reticle scope's. As with any program the more accurate the information you enter the more accurate your longrange accuracy. We have used Spot On to blow up 4 inch jar's of Tannerite at 600 yards previously.

Here's a pic of the Custom Turret on my .257 wby mag., zero is 200 yards.
