Great video, I guess that lots of guys will have easier times on deciding on which rail to put on the scope...

[@paulkonar7842]

Is the determination of which MOA (height) rail to use based only on whether you intend to shoot primarily between 0 - 500 yards (e.g., 0 MOA rail), or whether you intend to shoot primarily between 501-1000 yards (e.g, 20 MOA rail)? I certainly know that shooting beyond 1000 yards would generally be the same as the rail for the 501-1000 yards. I am just using 1000 yards for simplicity. Or, is it also determined by the dimensions of your riflescope? Are there other factors to consider? For example, I have a Weatherby Model 307 in 7mm PRC with a Vortex Viper PST Gen II 5-25 x 50 with a 30 mm tube. I intend to use the rifle for hunting between 200 - 600 yards, and long-range shooting out to 800 yards. The rifle comes with a PEAK 44, 20 MOA pic rail. Would using the 20 MOA pic rail be the best rail height for my intended shooting?

[@mountaintacticalcompany]

The base you choose is based on your optic and range you would like to shoot. Apply the formulas in the video to your set up and see which mount is needed. My 28 Nosler has a 40 MOA base under the scope because that was what was needed for the intended use of that particular rifle. Cheers!

[@dieselmakesmehappy]

Great Video. Thanks for sharing the knowledge! Best video I have seen explaining 0 vs 20moa rail. Ive got a 65Moa adjustable scope with a 20moa rail. A 100yard 0 leaves me with 51 MOA to play with.

[@charlesludwig9173]

@@renatosureal the bullet drop compensation function of a mil dot or MOA scaled reticle is secondary to the scaled reticle’s range finding function. It is better when possible to aim from center of crosshair, dialing to distance, because it supports recognition of consistent sight alignment, as well as parallax error using the eye’s natural ability to balance and center things. This is important because sight misalignment error increases with distance. At any rate, this is my perspective from experience as a Military Rifle Instructor assisting the USAMU deliver SDM Training.

[@charlesludwig9173]

@@renatosureal. There is no ballistic computation needed for an understanding here. All that’s needed is a ballistics app’s trajectory calculation for particular bullet/velocity. For example my 77 grain .223 loading requires 48 MOA come-up (480 inches) from a 100 yard zero to hit 1000 yard target in standard atmospheric conditions according to my ballistics app. My scope has 110 MOA elevation which means if I can get a 100 yard zero at about the 55 MOA point I can adjust elevation to reach a 1000 yard target with perhaps 7 MOA, or 70 inches of extra elevation at hand. Interestingly enough, I might still be inclined to place scope on a 20 MOA base to avoid dialing to end of scope range, which could happen in cold weather with dense air.

[@charlesludwig9173]

@@renatosurealIt’s not irrelevant because dialing to distance is always more precise than holding to distance, especially when wind is favored rather than dialed. At any rate, there’s typically no downside to a 20 MOA base unless it precludes a 100 yard zero.

So, if I understand this correctly. If you have a new scope/rifle with a 20 moa rail attached, the first thing you do, even before boresighting etc, is to click down the scope by 20 moa/5.8mil to adjust for having the 20 moa rail attached?And only then you go ahead and boresight and zero your rifle, which of course could mean you may have to further fine tune up/down depending on scope height etc. Is this correct? (assuming you have mounted everything else correctly etc etc) I know some of you say you should always boresight first thing, but I dont understand this because you already know that you are "wrong" by 20 moa so why not adjust for that first thing? That should at least make your initial settings closer to the correct settings? Please comment

I purchased a Warne QD cantilever 1” mount but feel like I need more height. The majority of my use will be at an indoor range.. so 25 yards.. but when I get to an outdoor range I’d like to be able to reach out to 100 to 150 yards.. My scope has 100 MOA for both elevation and windage. My rifle has a full length Picatinny rail and the Warne mount has a center point height of 1.43 inches.. Do I need any additional height to be able to reach out to 150 yards? I realize that my scope isn’t ideal for that distance but my use like this will be rare as compared to 25 to 100 yards.. 90% of use will be indoor at 25 yards. The reason I got a QD scope mount is because the rifle comes equipped wi some high quality vip up sights that I’ll use fro time to time. I may even try “lobbing” some shots in with the iron sights at even longer distances. Please advise.

So if at zero MOA the barrel and line of sight are parallel, then how do you get the bullet to impact where you are aiming ? Especially when as soon as then bullet leaves the muzzle gravity starts over and the bullet falls towards the earth? Is it because your line of sight is flat and the barrel is actually pointed slightly up to compensate for this?

Do I need to make an adjustment in the data in my calculator to compensate for the 20 MOA mount ? Does this change the holdover data? How does this affect the holdover points on the retical ?

[@mountaintacticalcompany]

Not at all. All your data will be the same one the optic is zeroed

[@AsifKhan-xs2qi]

A question from the admin or any 1 on this channel is if a sope has 120 moa's top to bottom then some experts says that to utilize all moa's u must have a 60 moa base So now how to find in millimeter or in inches that my scope base has 60 moa's Those experts also says that from rifle top (where the rail, ring base then rings r attached for scope) to the scope base u must have at least 1.5 inches gap or distance or height Any video reference or answer here

[@randyb703]

2:45 Why do we need 20, 30, 40 MOA mounts? Because rifle and ammunition has expanded our reach with reliability & consistency. And out-paced the design and ability of the scope's adjustment.

Cheers Mate!

[@2punish1]

I'm a beginner in long distance shooting. I own a 6.5 Creedmoor, and I have a SWFA SS 10x42 Tactical 30mm scope. The specifications for the scope state total elevation adjustment is 120 MOA and total windage adjustment is 120 MOA. Should I also use a 20 MOA rail?

[@mountaintacticalcompany]

2punish1 That's a great optic! Definitely go 20MOA or up to 40MOA if you can find one for your rifle.

[@2punish1]

Ok, thanks!

[@alanphillips1344]

For myself, I have purchased a Ruger Rimfire Precision, (don’t laugh, too expensive to shoot my 300 WinMag if I can find the ammo) in .17HMR. I was planning on a 50 yd zero but looking to go out to 300yds. Would a 20 moa be ok or a 30 moa?

[@mountaintacticalcompany]

There is nothing to be embarrassed about! Most shooters who want to maximize their range time without spending a ton of money buy a rimfire to mimic their primary centerfire rifle. What rail you need is a function of the scope, as stated in the video. Use the calculations in the video to figure out what angle your mount should be. Cheers!

[@alanphillips1344]

@Miles Maillet sweet! Very flat shooting but the main thing, just like shooting a 22, it’s cheap to run. Before the ammo price jump, I purchased every box I could find. At about 5k now, but that gives me the ability to spend a day at the range and go thru 200-300 and have fun. I mean, 50 round boxes with an average cost of $12.00, that’s cheap fun!!!!

[@glennroberts461]

Huh? I think he said that if you have a scope set for 0 MOA and a 0 MOA mount your scope is parallel to your barrel line of sight. And I think that is correct. But what that means is YOU WILL NEVER GET A ZERO CROSSING AT 100 YARDS, OR ANYWHERE ELSE. You must always account for the offset of the scope height above the barrel. Mine is 2.1 inches so at 100 yards that is at least 2 MOA down plus whatever ballistic drop their is at 100 yards. I sight mine in to be 2.3 inches high at 100 yards to give a zero crossing near 250 yards. I know my mount is definitely not a 0 MOA mount but don't know exactly what it is. All I know is it works.

[@hemp64731]

Didn’t even know this was a thing. Glad it showed up in my feed, question, would I have to now worry about my scope height after putting the mounts on if I did this conversion?

[@pcjpcj4070]

Great vid. Been seeing alot of vids on long range hunting with the 6.5 creedmore but very little on terminal ballistics on that round at 1000 yards where 20 extra moa would be needed in a lower end scope. No energy or speed at that range so no need for it unless just target shooting or small game. Now if you were talking 300 win, ultra, 338, 264 win mag or even a 6.5x284 I think it would be leading people down the right path. Liked the video just bad example with 6.5 creedmore and 143 grn hunting bullet balistic wise doesn't have it to need the extra moa

[@mountaintacticalcompany]

We used 6.5CM simply because it is a round that most people are familiar with right now. As I say in the video, I would never use it hunting at that range. This video was about optic mounts so ballistics of different calibers were not a consideration here. I appreciate the feedback for future video ideas!

[@pcjpcj4070]

@@mountaintacticalcompany Its a good video. You explained it better than I could. Going to have my 15 year old watch it. Tried to explain it to him the other day when he was wanting to change out his stock rail on his new savage 338 lapua. His HD Razor has 135 moa, and until he can shoot to the bottom 10 of that, there's no need for him to swap it out. Better now to spend that money on brass and powder. Thanks again

[@mountaintacticalcompany]

@@pcjpcj4070 he's going to need lots of money for powder with that bad boy! Haha!

[@kingduckford]

I like to talk up the 6.5 Swede, being that it is so much a part of Scandinavian shooting and history, as well as a great round in its own right. I'll bring up that it has been used to kill more moose there than all other cartridges combined, and has great versatility, but one day you start regretting saying such things because people get idiot ideas like using a 6.5 CM to take pot shots at animals at 600 yards, where decreasing terminal performance for all bullets is a major issue, along with shot placement. So, I'll bring up the caveats to my 6.5 Swede moose killing point. The one most people mention is that the moose up in the Norse lands are smaller than their North American counterparts. The point I like to draw out is that a the 6.5 Swede does a great job on bigger animals because they use heavy weight bullets with big boi sectional density, like the Norma 156 grain Oryx, or 160 grain old fashioned round nose, not lighter weight 140 grain bullets. In a caliber small as .264, the lack of objective weight, that sectional density and extra weight are huge differences. The shapes and weight of bullet for hunting may not be the kinds you want to use long range anyhow. Second, those Scandinavians take great pride in marksmanship, yet a lot of those moose kills are at closer ranges from old hunting spots in the woods, not half a mile sniper shots. So, as far as hunting goes, the 6.5mm 0.264 inch is a capable killer, even on larger game, so long as you keep your distance short, your aim true, and the proper heavy bullet of good construct. However, no matter how great a long range match cartridge it is, it is a poor choice for long range hunting. Punching paper smaller may do as well, but in lethality sometimes there is no replacement for weight and size.

[@scootertrasher1369]

You could just say a 20 moa rail gives your 20 moa more elevation rise for longer distance zeroing

[@dial0foroperator]

That takes way too short a time. Way too simple.

[@rodneyalaking8241]

Suburb A Knight I was thinking the same thing! He has to show us how smart he is!

[@marcrobert2603]

20moa at each 100m/110Y, so 200moa at 1000m/1100Y. or plus 5meter or 5.5Yard. or something. But your bullet drop is extreme fast at those distances.

[@wisetow10]

He did say exactly that. Just in a much more informed way for people that would search this video. Glad he added all the detail. Be sure and give us the link to your 3 second video explaining this the short way.

[@pd2865]

I wish you would do a video on a 20 moa rail with milliradian reticle and who that works.

[@mountaintacticalcompany]

It works exactly the same. Mils can be converted to MOA if you want to plug numbers into what is done here

[@dannyb.4034]

Good info

[@gregb8823]

Have a Nighforce SHV with 100 MOA mounted on a 20 MOA base zeroed at 100 mtrs. Went shooting on weekend at 1200 mtr targets. Ballistics said I needed about 62.7 MOA to be on centre of tgt. Could only dial 54 MOA WTF. Have I missed something as I assumed I had about 70 MOA of adjustment. On a side note I got on with 50 MOA wound out and 5 MOA adjustment using hash marks in scope. Re checked zero at 100 after shoot. Wound up 58 MOA and down 37.5 MOA. Thats not a 100 MOA scope.

[@VLK-73]

So if I understand this correctly, the purpose of the 20 moa rail is to be able to keep the crosshairs dead center on the target at longer ranges, essentially compensating for the bullet drop...correct?

[@mountaintacticalcompany]

The purpose of a 20 MOA rail is to increase the amount vertical adjustment in the scope so you can dial your turret for longer shots.

[@dps6198]

When your scope has a 30mm tube or larger you have more MOA elevation than a 1" tube. Some scopes have tubes larger than 30mm so you'll have more elevation to work with. The challenge is buying scope rings. The gun store where I used to work had rings on hand for 30mm tubes. Rings for tubes larger than 30mm had to be ordered with an unknown delivery date. So before you drop coin on a scope with a larger tube order your scope and rings at the same time.

[@teacheng3795]

Useful, though I'm still working out how a downward canting 20 MOA rail lifts my range up. A little more step by step on that part would help

Watch the part with the diagrams again. It's all step by step there.

Is 1310 yards more or less than 6 feet? How many stones or gallons would that be?

[@TMFShooting]

Excellent , Very good ' 💥💥💥💥💥💥💥

[@DLN-ix6vf]

If you had say 6 targets @ 200 yds totalling some 498 points ( 1 point for each 1/8th" ) / 6 = 83 points average and you write down .830 then subtract the first number of 8 plus 1 = 9 from the total ( .830 - .009 ) the number would be .821 MOA. Correct answer ! This only works with 1/8th point system, 1/16th or say 1/4th will not work unless you do additional math. There is a longer formula to convert to MOA but you need a calculator. Why does this only work with 1/8th / point ? ANYONE KNOW ?

[@vinago100]

Just mounted a 20 moa base on my rifle. I typically shoot 100 - 300 yards. Should i have bought a 0 moa mount instead?... My scope is a vortex viper hs-t 6-24 x 50mm if it matters at all...?

[@mountaintacticalcompany]

How does your optic match up with the data provided here?

[@REBELSCL]

Any reason to use a 20mm rail on a 22 lr M4 that I intend to use at ranges of 25 - 200 yards? (3-9X40 IR AO SFP scope)

[@mountaintacticalcompany]

Going to 200 yards with a 22lr? 20 MOA may not be enough. But in your set up, your optic will be the limiting factor for range.

[@MiddleOutdoorsman]

So, if I understand this correctly, 0 MOA rail for standard hunting ranges, 20 MOA rail for long range target shooting?

[@mountaintacticalcompany]

Not necessarily. We use our turrets all the time hunting and need a 20-40 MOA rail to do so effectively

[@chefboyflavs6592]

I know there is 3 MOA per MIL (Rounding down) but if I buy a scope that says it has 20 MIL adjustment going up and 20 MIL going down, in theory I would be able to use a 20 MOA rail as that would be give me over 120 MOA correct?

[@mountaintacticalcompany]

I think your math is a little off... but the premise is the same for mil and moa.

[@chefboyflavs6592]

@@mountaintacticalcompany is it not 3.438 MOA in one MIL? So the same rule of 51 or more applies to MIL Scopes as well even though 20 MOA being about 20 inches at 100 yards would only be close to maybe 6 MILs? Sorry for the questions, I am pretty new to all this and I have a scope that is in MILs and was hoping I could use a 20MOA mount to extend the range of it without needing to have to buy a new one
