CANT do this, CANT do that!

[Gila]

A little humor in the title...

An optics “expert” has suggested that for my model of scope that I mount a 20 MOA pic rail. He also suggested putting 15 MOA into the rings. I understand that the total 35 MOA cant will allow me to sight-in toward the bottom of the elevation range. It is a 300 win mag, the scope is 18x max power. Is there any other consideration? I have sighted in my other rifles without a base at 200 yards. Should I sight this one in at 100? Thanks in advance.

How far do you plan to shoot? A 20 moa rail is plenty for most cartridges and scopes to make 1000 yds.

1K is good enough for me.

 

[wapitibob]

a 20 moa rail should work -but- you will need to look at total vertical travel of the scope

Does your scope have a zero stop?

Enough elevation in the base and rings can act as one. I’m not suggesting go hard stop against the bottom of your adjustment, but if you are less that a full turn back from your zero you are not lost in the dial.

Forget all the above if you have one.

Yes I have a zero stop. I wanted a zero stop to keep from getting lost in the weeds. I have a FFP and good numbers on the reticle for a hold over but want to trust the dial-up at 1Kilo.

About 110 MOA elevation range so hoping to get toward the bottom for a bore sight. I think 35 MOA is a little excessive for what I want to do but why not I guess is a good question.

Personally I think everyone’s zero should be set at 100 but that’s what’s great, we all get to decide for ourselves, for now.

Most of my shots have been 150 to 250 yards. I will be doing hold over most of the time, so 200 yard zero makes sense to me and that is what I am used to. But for dialup I see the advantage of a 100 yard zero.

With the amount of travel in your scope you’ll be fine with a 20moa rail

This is what I do.
My hunting rifles I zero at 200 and hold.
My "precision" rifles where I plan to dial I zero at 100.

20 or 35 moa, doesn't matter for your purposes. I would go 20 MOA base because adding it in the rings means you are stuck with a one piece ring or those plastic inserts. Also, I don't like to be at the extremes of dialing if I don't have to, but that's me with no data to support it.

100 yard zero is best if you intend to shoot beyond 400 because it eliminates as much environmental factors from your zero when you dial for longer shots.

If you want a 200 yard zero when you hunt and use holdovers, just dial on the 200 yard dope and roll with it. Holdover like you want, and if you shoot further, you can dial. Or, dial and slip the turrets and just track dope to return it to zero.

Would 35 MOA cant work? yes. Would 0 MOA cant work, also yes. I'd be basic and just use 20.

You mentioned shooting at a kilometer. There's a good chance you wont even be up to the center of your scopes travel yet when shooting that far with a 300 wm with 35 MOA cant so it seems excessive.

Zero at 100 yds. Dial up to 200 when you go hunt. Best of both worlds.

In regards to cant. I just pulled a 20 moa rail off and plan on it for more that I’ll never be taking over 1k. That said my Scopes have plenty of travel.

 

[Antares]

I wouldn’t bother with the rings, just the 20 MOA rail will be sufficient. That scope and 35 MOA of cant in the mount will get a 300WM out to 1700+ yards.

I like that....definitely for me. I am going with the 20 MOA rail and 0 cant on the rings. 100 yard zero makes sense. My rangefinder will spit out elevation in MILS out to just under 1KMm but no enviro data. I have been using Strelok Pro and a Weatherflow for enviro to do dialup.

I found out that the elevation travel spec that I was given is total travel which includes windage. It is 77 MOA of elevation and 30 MOA for windage. The scope designer suggests 20-30 MOA of cant. I am going with a 20 MOA pic rail and also going to put 10 MOA into the rings for a total of 30 MOA of cant. I am going to zero at 100 yds and then dial up 200 yards before I go into the field.

I would like to have locking turrets but will just have to see what it takes for a turret click. I have carried around exposed turrets for several seasons now and have not had any accidents yet. I have been using a neoprene cover when I strap the rifle to the backpack. Anyone have any issues with the Burris XTR rings?

 

[khuber84]

20 moa is more than enough. To get back to optimal center of your scope w/ 30moa you'll have to be shooting around 1k yards.

 

[deadwolf]

You only need the 20moa rail, skip the 10moa rings. You came here for advice, and people are trying to steer you right.

Your scope has 110 MOA. Optical center is therefore 55 MOA.

A 20 MOA base will get you 55+20 MOA or 75 MOA, or 1600 yds with a 190 gr SMK per Federal.

Edit: just read additional post, who the heck ADDS windage and elevation?!?

Optical center is 38 MOA, so a 20 will get you 58 MOA, or 1400 yds.
