Why you should avoid cheap optics
Переглядів 54210 років тому
As a gunsmith and firearms instructor I often get asked which is more important when putting a precision rifle together- should someone get the best rifle they can afford and get a lesser scope or the other way around? My answer is always the same. Spend the money on the optics! An out of the box savage with a Mk4, nightforce, USO, etc. will always shoot better than a $10k rifle with a $100 (or...

Setting the headspace on a Savage Edge .223. This rifle came in with so much bluing salt residue in the chamber that once we cleaned it all out, the rifle had excessive headspace. This clip is just a short tutorial on correcting the problem.

@1:12 Dude just annoyed landscapers, surveyors, flooring installers and every sports field manager
So would I have to add .2 for 1400 range
why do so many make videos and don't understand that the unit of measure is radians, and mil only means 1/1000th....please get your crap together and actually talk mrad or milliradians
What about the recoil lug, my savage has one what is different with yours
2.5 seems to be the constant for 556 to get it to 2 mils. what most people say is the 10 mph wind hold at 500 yards.
Thank you for the video. The order of operation with the go gauge and remage nut was helpful. Thanks.
What is the constant for 6.5 creedmoor
Can you input range in metres for this formula?
So do you use this in conjunction with moa to find your adjustment like after you find your range you plug it in with moa
WTH?
What is the constant for 556?
Very handy.
Where do you get the constant from?
I was confused about what one mil was
Thank you so much you explained in a way I can listen and pay attention
This is not the correct way to headspace! Do Not leave yourself room to play with! Your gunna get somebody killed with bad info for a noob doin diy at home!
Great video! I've recently rebarreled my Savage. Using the go gauge I threaded the action on until it was lightly snug against the barrel and then i snugged up a little more firmly. My question is what are the signs of having the headspace too tight? I am able to chamber the go gauge but the bolt handle doesnt fall into lock. I have to assist it to lock with light effort. Thanks!!!
Prob lap your bolt and lugs a lil bit with a lil bit of 500 grit aluminum oxide and some greese and kroil oil till it is running smoother and make sure it won’t close with a no go and you should be golden
Excellent
Well. you mention how to measures the target ok, but for me was not satisfying, do to a lack of explanation me never saw Exactly how to use the Cross hair with respect to mill and dot, a lot of peoples that never has seen a through a telescope using the cross hair and the target to get it hit. sorry if my explanation is not clear thanks for your patient.

Does this formula really works? I want to see a video of this formula being tested. No physics involve. It's as easy as adding, subtraction, multiplying and dividing.
Thus should be labeled "checking headspace" Not headspacing...
Nice. We'll that's all good for mil guys. What about us MOA guys? Is the math the same still? 🇺🇸 2A 🇺🇸
So what is the constant for a 30-06 18ogr And how do u get a constant for each Rifle and were do u get this information? Thanks Good class brother. 🇺🇸 2A 🇺🇸
All your calculations add up into Mills. How do you calculate that into MOA? Thanks
Pretty sure you times it by 3.44 if I remember correctly
I love the show very nice. But tell me how do you get the Numbers for constant for each caliber
Thank you... I must have watched 15 videos before I came across this one and saw that you actually moved the barrel nut...
We dont know how we find the constant of our bullet. Please help us??
Hi sir , can i use this formula with metric système , for the Wind i use m/s and not mph, and should i use the same constance with metric formula , 308win (4) ?
No. You need to multiply the constant by the conversion factor between mi/h and m/s.
Thank you! Never would have thought this until I saw it.
Thank you for this video. I had a sneaky suspicion that my factory rifle, which does not group well, might benefit from unscrewing and re-installing the barrel. How much would you charge for this? Or would you recommend people just buy the appropriate wrench and gauges and screw myself?
OMG how about talk in modern millimetre .. Spray can 250 mm tall . it is not a inch radiant scope it is a Mil radiant . Do a Video talking in Mil so the rest of the modern world can understand . at 100 meters = how many mm at 200 meters = how many mm
A milliradian converts to 1/1000 of ANY unit, we're not locked to mm. Coming from MOA we're already using inches...
Good method ! Anyone knows the constant for 6.5 creedmoor ?
MOA constant is about 17 at 1000 yards.
Question : zooming in on target will affect the space it takes up on the hash marks... I don’t understand how you can calculate range if the targets size on your reticle depends on your zoom level... no? Help me lord
very late reply so I'd assume you have figured it out by now but that's where first and second focal plain comes into play. First focal plain reticle changes with the zoom where as second does not which yes would affect the calculations so it is only going to be accurate on a certain power of zoom, generally the highest or close to it.
And or fixed power like the 10x42 as, Which may not apply as the question was reticle size changing, Been told thier are hacks or shortcuts about those changing reticle but I ain't even mastered this one,,, I ain't even sure what I have,moa moa or mil moa or what. It's got mil dots jeezzzz
To be accurate use a FFP mils scope. So it will be accurate at any measurement through the rectcle.
The horizontal line it serve at what??
A savage is one the best rifle for accuracy on the market.
Yes i agree And that big ugly barrel nut that people complain about is exactly why. Provided barrel is floated.
I love mine. I bought a Savage Axis off of a guy for 200 bucks, took it to the range, and shot a string of .5 groups with it using factory ammo at a hundred yards. I put a Shilen Barrel and an oryx chassis on that action and now it shoots right into the same hole, more times than not. If you optimize your trigger and just make sure your Barrel is free floated, then they are superb!
thats why our constant increases - said no one ever who knows what constant means.
Try that on a Coyote Stand, pre-dawn in -17 Wind Chill and two coyotes coming in. lol
Ready to go? Where's the recoil lug???
That particular gun (savage edge) doesn't use one like the axis and 10/110 rifles.
@@jacobwhittaker6241 OK, I learned something today. Thanks.
It doesn't matter what unit of measure you use. All you have to do is take the target size (in whatever unit of measure you want) and multiply it by 1000, then divide it by the number of mils it covers. THEN, after you've done that, convert the units to yards. (Or meters, or whatever you want to convert it to) Example: A Target that is 12" tall. 12" x 1000 = 12000 inches 12000"/# of mils (let's say 3) = 4000" So the target is 4000" away. NOW we convert inches to yards. 4000"/36"(the number of inches in a yard) = 111 yards away. Another example, a target that is 57" tall (a completely random number) 57"x1000=57000" 57000"/4 (or whatever # of mils it is) =14250 inches away 14250"/36" (inches per yard) = 395.8 yards away Simple.
Very good
If doing it in Inches just use 25.4 for the multiplication and then divide it and BAM you get meters away which most of the world would enjoy(Mortars and Artillery at least want it in meters lol)
Well explained
Do the formula in MOA, not mils, for a multitude of reasons, like when your scope or sights are in MOA, or when using irons which will require hold off in inches. Here's the formula: distance to target in yards divided by 100 times wind value in MPH divided by the constant. Now how do you determine the constant? The MOA constant for any distance can be determined through a trajectory calculation produced from an online ballistics service. Just think what the distance in yards divided by 100 times wind value in mph needs to be divided by to produce the trajectory calculation's given MOA adjustment for a 10 mph wind. Using the .308 (175 SMK @2610 fps) at 600 yards for example, 600 / 100 = 6 X 10 mph = 60, so now what would 60 need to be divided by to equal the 5 MOA stated wind favor from the trajectory calculation? The answer is 12. That's the constant you will then use to determine the wind favor in MOA for any wind value at 600 yards for the specified loading. For 1000 yards the constant is 10. This stuff is easy; but, if you have difficulty with wind, seek a credentialed coach/mentor. Most credentialed is a shooter holding an NRA Long Range High Master rating. Ask your coach/mentor what wind constant he uses for 600 or 1000-yard competitions. If you get gobbledygook instead of a straight answer, move on to a more qualified coach. Creds: US Distinguished Rifleman, NRA American High-Power Rifleman, SAFS Coach, and SDM Instructor.
Great video . I always neck size my 270 brass after first shot which is custom fit to my chamber . Brass height is as SAAMI spec . But when ever i try headspace guage it does not fit properly . Now my question is does my rifle has headspace issue ? Do i need to continue neck sizing or i should show it to a gun smith ?
What would be the constant for a 5.56 ? Like MK 262. And in what distance would add .1 in the formula? Thank you .
The MOA constant is 10. For example here’s the formula for a 10 mph wind at 600 yards: 600 yards divided by 100 equals 6 times 10 mph wind equals 60 divided by 10 constant equals 6 MOA wind drift or 36 inch favor.
Thanks for showing one you didnt have to do anything at all to.
How do i find the constant of my bullet
Luke Shave , Get the G1 BC so if your G1 BC is 525 than your constant is 5. If your G1 BC is 400 than it is 4. On the range you can true and find out exactly what MPH your bullet or gun is. Bit late but hope this helps someone out.
@@Bk7820-e3d a bit later than you but thanks for the info. It was my question too.
inches x 1000 / mils / 36 = range in yards (inches x 27.77 / mils = yards also) inches x 25.4 / mils = meters
Marine corps doctrine 💪
Don't you know the difference between a gun and a rifle receiver and proper torque of barrel installation ?
Hey great Video! Do you torque that barrel nut at some point?
Thanks for the wind formula. I use MOA adjustments instead of Mils. All I need to do is multiply the answer in Mils by 3.44 to get an MOA adjustment. Accuracy is getting better every day.
