Fieldcraft Am i able to reach 1k

[brianb1998]

Ok everyone hears my situation.

I have a remington xcr 308 with a leupold mark4 4.5-14-40 that has 100 moa of adjustments.

Zeroed at 100 is 60 clicks up which leaves me with 150 clicks left over.

will that be enough adjustment to adjust to 1k with out using holdover?

Re: Am i able to reach 1k

If the scaope clicks are 1/4 MOA then Yes, with some ammo. But start thinking in MOA of Mill and not clicks. Zero your scope out and start recording how many MOA it takes to get to different distances. Good luck

Re: Am i able to reach 1k

That sounds like 1/2 MOA clicks now that I added the numbers up. 155 Scenars and 175 SMK or 178 Amax will be good bullets to play with at 1000 yds and you can find ready to go. Try SW Ammo. I would stay away from the 168 SMK loads for 1000yd play. But inside 600ish yds you shoud be fine with them. Good luck

Re: Am i able to reach 1k

I think i was off. so after centering my elevation turret I actually have to move my poi down 60 clicks or 15MOA which would mean I now have 270 clicks or 67.5 MOA to move my poi up. Thats a lot better right?

also is there a reason they dont move the 100 yard poi toward the bottom of the scale so you could have much more adjustments to reach further?

Re: Am i able to reach 1k

Do you have a 20moa rail under that scope or just 0 moa mounts. I think you should have plenty of play, if not slap a 20moa rail underneath and you will be sure to have enough.

You might also give the new Hornady 178gr BTHP a try. They've got a great BC and should be stable out that far.

Re: Am i able to reach 1k

yeah its the night force 20 moa base/rings

Re: Am i able to reach 1k

Depending on the scope your using you could zero at 100 yards near the top of the scope (say 10 moa up or whatever is easy to identify) then you'd gain that much more for you elevation change, and not change a single click until you reach at least 10 moa of adjustment. You could also spend a little money and get a cheap 20 MOA base. The real issue though would be making sure your load of choice is not getting subsonic or transonic (just above the speed of sound) at 1000 yards. Once you get to that transonic regime some weird things start happening to the bullets trajectory. Not to mention that your wind corrections would get exponentially larger.

Re: Am i able to reach 1k

Just to give you an ideal:

I shoot a M1A at 1000 in service rifle. Iron sights. My 200 yard elevation is 11 from the bottom. My average 1000 yard zero is 48 clicks from the bottom.

These are 1 MOA clicks. (I get 1/2 MOA using the hood on the rear sight).

This is using 175 SMKs at a hair under 2600 FPS.

If I was using 1/4 instead of 1 MOA, that would be 196 clicks from the bottom or 148 1/4 MOA clicks from my 200 yard zero.

Take into account also these are iron sights and I use a 6 o'clock hold so in reality, my impact is 22 inches (2.2 moa) high.

Adjusting your 100yd zero so u impact high will not give you more adjustment at 1k because u already used the 10moa at 100. The only way to gain adjustment is to add a canted base or use the mil once you've maxed out ur turrets.

Re: Am i able to reach 1k

FWIW you generally need 34-38 MOA from your 100yd zero to get to 1000 yards. You should able to check your scope once you're zeroed at 100 yards and see how many MOA you have left. As the previous posters mentioned, count your adjustment in MOA and not in clicks. All scopes are not created equal and 1 click on one scope may equal 1/4 MOA and the next scope 1 click may equal 1/2 MOA, or even 1 MOA. Check out your knobs to see what each click value is and do the math from there. All the Mk4 scopes I've used have 1/4 MOA click values but double check to see what yours are.

Re: Am i able to reach 1k

Data I've got on my 175 grain SMK load (at 2700 fps) show a 25.67 MOA drop at 1000 yards. I've only done local load testing to 100 yards, will be field testing this to 1k Mem. Day weekend.

crunch the numbers on your own ballistics app, or on the JBM ballistics page.

I've shot to 980 yards (on torsos) using 168 gr SMKs through a 26" PSS, friend of mine using the same model rifle and load made two consecutive head shots at that range. It's doable (my data for the 168 SMK shows 28.5 MOA, but in reality I recall dialing in about 35 MOA, don't have my log books at work with me).

No offense brother, but from my personal experience you're going to be nailing the 800 or 900 yard berm with only 25 MOA dialed. I'd venture to say your actual come-ups will be roughly 32-34 MOA at those velocities.

I agree, depending on DA the come ups should be between 34-40 moa.

No offense taken. Like I said, data I had on 168s wasn't even close, I expect I'll be dialing up a whole lot more than the program says for the 175s as well.

Re: Am i able to reach 1k

I get to 1000yrd no problem with 168s and 32MOA.

Just go do it and you'll see that you can do it no problem, you have more than enough scope and elevation left in the scope to do it...

Re: Am i able to reach 1k

Running the ballistic calculator using the chrono data I have 175 gr FGMM will require around 42 MOA at 1000 yards. My 168gr SMK Handloads require 40.6 and my 168 gr berger vld loads require 36 moa so I would say you should need 35-45 MOA depending on your loads.

I am guessing your scope is .5 MOA per click as you mentioned 100 moa internal travel and 210~ clicks total so that calculates out to .5 MOA clicks. That being said 60 clicks is 30 moa. the 150 clicks you said you have left give you 75 possible MOA of come up so 1000 yards should be well within where you can dial on your scope.

Re: Am i able to reach 1k

I run a mild load for a 175 Sierra. I also have a 20 MOA base and it takes me 39.5 MOA to get to 1000 with 100 yard zero
