.223 SPR (77gr SMK) - 100 or 200 yard zero?

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
I wonder what the point would be for a 100 or 200 yard zero. I prefer a Matech sight set for a 300 meter BSZ, which, even with 77's, tracks well; and, therefore, makes the rifle a versatile one, able, with proper adjustment, to hit KD targets out to about 600 meters with a center of mass hold. Maximum ordinate is only about 7 to 10 inches at 150 meters, with sight set for 300; and, at 350, bullet drop is only about 10 inches low. For 4, 5, or 600 meter KD targets, of course, the sight can be adjusted for center of mass hits. Additionally, the sight can be hastily re-set for a 200 meter zero to avoid the possibility of shooting over at close distance. Use of an ACOG, such as the 31F, covers, in a heartbeat, all scenarios the BUIS possibly could not adapt to when it is initially adjusted for a 300 meter center of mass zero.

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
Maybe I'm thinking of a different application, but if you are in a KD environment, why not dial for each range, why use a BSZ that only gets you close?

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
The BSZ is used in UKD scenarios out to 400 meters with BSZ set for 300 meters. For KD scenerios, BDC is used for 400 to 600 meters (M4, or M16A4). BTW, I have been talking about scenarios with a service rifle and irons; but, conceptually it works for optics too.

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
Different strokes for different folks, I suppose. I prefer the so-called "improved battle site zero". Since my SPR dubs as my varmint rig, I really do prefer a 200 yard zero, where I get to enjoy no more than 2" of "rise" between me and about 230 yards. Most of my UKD shooting is realistically happening within 200 yards and on targets generally much smaller than humans. Beyond that, I'm likely shooting placed targets and/or something I can range. I'd prefer to dial in my dope for a precise shot.
Using the same 300 yard zero trajectories for center mass hits on steel/human sized targets, 200 zero still allows me to get out to about 335'ish yards for an UKD shot.
I virtually never use irons and I'm not much of a fan of BDC reticles for such an application.

The Matech BUIS allows you to have your cake and eat it too. After establishing a 300 meter zero, it can be clicked hastily for a 200 yard zero; this is in addition to its BDC function.

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
I use a 200yd zero for several reasons:
- I use an NP-R2 reticle on my 2.5-10x24. This allows me to use my comeups from my years shooting highpower on the reticle for holdovers
- Since I shot highpower, the shortest range was 200, if I shoot inside of that, I adjust (or hold under) down 1.5moa to hit 100yd.
- Again, with my known comeups from highpower burned into memory from years of shooting Leg matches and Regional courses of fire, basing everything from my 200 zero is second nature and I KNOW that my 75gr @ 2650fps load is up 3 for 300, 6.5 for 400, 10.5 for 500 and 15 for 600.
It's all in what you the shooter is comfortable with and can remember best.

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
I use the NF 2.5-10x24 with mil dot ret. I sight for 250 which puts me at the bottom edge of the first mil dot up at 100, about 2"high at 200 and on at 250. I dial .7ml for 300, 1.8ml for 400, 2.8 mil for 500 and 4.5 mil for 600. Works for me. I shoot from about -10 F to 90F. I find for each 40 deg temp change, my POI is changed .2mil.

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
I prefer a 50 yard zero because your zero is less affected by the wind, it is pretty close to a 200yd zero and flys flatter between 50 yards and 200 yards(less rise at the peak of its trajectory). You can play with a ballistics program to prove this out.

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
Ballistics program suggests a 50 yard zero is about the same as a 120 yard zero.

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
Bailey,
What program are you using to get that data and make those charts? Just curious, as those charts are very well done, and I wouldn't mind using it myself.
As for me, I tend to use a 100 yard zero and dial for scoped rifles, but use a 50/250m IBZ for my 16" AR with M193. Once I get my SPR finished, I'll likely be taking a hard look at changing to a 200 yard zero, depending on what kind of data I get for my chosen load now that I finally put two and two together that doing so would provide the same benefits I get with my 16-incher.

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
Your sight height is listed as only 1.5 inches above the barrel, mine is measured at 2.8". That will cause a big difference in calculated values. In any event, my 50 yard zero and 200 yard impact confirm they are the same for me.
Cheers.

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
I am new to the precision ar field but I have had good success. Setting my zero range based on the size of the kill zone I am working with. When I hunted pdogs with my air rifles I used a 45 yard zero that got me Inside a 1" kz out to 55 yards. If the critter was inside 55 yds, just point and click. If I underestimated the range I would still score a solid neck/chest shot. The last thing I wanted to do was overshoot a close shot because I forgot to dial or hold down.
With my spr I use a 200 yd zero that gets me a point blank range on a 4" target of 230 yds. I have considered a ~250 zero that gets me an 8" point blank range to 290, but I don't like the 4" apex at the 140 yd mark. Seems to high over line of sight.
I like to point and click as much as possible.

It's "Ballistic FTE" for the iPhone by Jonathan Zdziarski and is based on JBM. Easily the best ballistics app on either the iPhone or Android, imo.

Thank you, sir. Sadly, I can't seem to find it on the Android Market. Might be because I have an older Android, but maybe I'm SOL. That's OK, JBM works just fine for now.

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
+1 for Shooter.
There was an old trick some tactical shooters I knew used with mildots and 7.62 (both M118 and M852):
zero at 300
down to bottom of dot for 200, top of dot for 100
up a mil for 400, 2 for 500 and top of 3rd dot for 600
By the way .... works for MK262 also.

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
200 Meters for everything in inventory with any sort of optic - including the 77 SMK which is my load for the local long range 3 Gun speed matches using a NF 2.5-10.
Life is simpler that way and hold over/under is pretty simple including at 300 and 150. Important enough if you are running a SFP optic and not on max power, which I seldom am. (I dial in adjustment for the 400-450 yd shots, since that's as fast or faster than cranking up the power.)

There was an old trick some tactical shooters I knew used with mildots and 7.62 (both M118 and M852):
zero at 300
down to bottom of dot for 200, top of dot for 100
up a mil for 400, 2 for 500 and top of 3rd dot for 600
By the way .... works for MK262 also.

Re: .223 SPR (77gr SMK) - 100 or 200 yard zero?
I zero my SPR at 100yd. However, when I go varmint hunting, I dial elevation to 200yd and leave it there for the trip. That way I have the best of both worlds.

50 yard zero then should cross again somewhere around 200
This is the new improved zero for the military

Interesting. Parris Island as well as Fleet quals for 200 offhand 8/3 - 2 was drilled in to my head as the proper range setting on an M16A2.
Consciously I remember little else from that time save my green data book with a galvanized 16D nail attached.
Subconsciously those days are still in my head driving what I do without me realizing it.

I was contemplating what zero for my spr-ish rifle as well. Decided I would do a 100 yard zero and then just know my 200 yard dope on the dials. This way at a known distance range I dial for everything, then at an unknown range (ie hunting) or a high speed environment (ie 3 gun) I just dial to my 50/200 zero and can point and shoot. Haven't been able to test this theory but it sounds good on paper.
