Here is the latest setup and results.

That is 90 round group at 100 yards with the addition of the bipod i am able to keep it on target much better. Really love this Sig 516

Had more fun with the SIG 556R this weekend.

Round Count: 200 rounds thus far.

* Tulammo 7.62 x 39mm, 124 grain, HP

Outfitted with my SIG 716's former Aimpoint CompM4, we started blasting away.

For those of you who've spend time commuting through The Tube, this gives some meaning to "Do Mind the Gap..."

The gap between the scope and bore axes, that is.

These were fired at a range of 15 yards, and I was hitting way too low until I realized what was happening...

I made the corrections to my hold before the *** gasp *** clip went empty.

The Walking Zero

I was pretty sure the rifle was nicely zeroed away for 50 yards the last time I used it, however...

These shots were fired with elbows only on the table.



Rechecking zero with the Lead Sled, things seemed to be okay...



Tried elbows only, again...



Needless to say I was perplexed.

Unfortunately these shots were fired shortly before the range closed for the day.

Imagining all sorts of fancy scenarios causing the shots to localize in Quadrant 3,...



...I came up with the following explanations:

1) The pencil barrel had heated up significantly to affect trajectory! Probably not.

2) My cheek weld with this rifle isn't as established. The zeroing shots were aimed with the red dot sight looking through the rear diopter; this was done to eliminate the "blob effect" induced by our eyes' inherent refractive errors on different planes (that's called astigmatism, I believe).

If Visual Acuity is less than 20/20, perform the pinhole test, by checking Visual Acuity again having the examinee look through a pinhole. The pinhole allows only central light rays into the eye, so refractive surfaces of the eye are not used. If there is underlying refractive error, Visual Acuity should improve with the pinhole test by at least one to two lines. If there is no improvement, refractive error is less likely to be the cause of poor Visual Acuity; further examination must be done to look for intrinsic eye disease.

Aiming through the rear diopter also had the side - benefit of ensuring constant cheek weld.

The subsequent "fun" shots fired with elbows rested were done without looking through the rear diopter...

Which leads me to believe that although minimized, one can still experience the effects of parallax with red dot sights, even Aimpoints.

Just the musings of a novice shooter...

...who's trying to come up with reasons to obfuscate what really amounts to poor shooting technique!

I'll need to test this idea by shooting all rounds aiming through the rear diopter and red dot sight next week.

Not really part of the Range Report, but I have to say...

From a design standpoint, they really got the SIG 556R's Bolt + Carrier combo right.

Big parts, simplicity in design, rides on rails with large gaps.

Functions so smoothly, even without any lubrication!

Probably because the groove in which the cam rides in is part of the bolt carrier, rather than being part of the receiver.

What I really like is that I can chamber a round slowly and quietly by "riding the bolt!"

From justdave: SIG 716, Vortex PST 4-16x50; SIG 516, 1 - 4x Vortex Razor, 100 yard groups

It's 168 match king over 44.0 reloader 15. Because most of my .308 stock is 147 grain ball, my next venture will be with 155 match kings and xbr8208. I've decided to try this combination so there will be little difference between my show off load and my plinkers. That is a 1 inch orange sticker. I shot 3 rounds, made a correction, and shot 3 more for a group using my versapod and rear bag.

I got out and did some more research over the weekend... Let me start by saying I've been reloading for better than 10 years. I'm no expert but, definitely not at a novice level. For those interested in reloading, hang out at the local gun/reloading supply shop and listen to the old farts, you will learn something frequently. I am primarily a bolt gun guy, the accuracy potential is what drew me to Sig AR style rifles. I've been able to make other AR's shoot well and, I'm digging my Sigs. To lend a little credibility to myself, here is a target for my .223 Ackley that I've just finished load development for.uploadfromtaptalk1374638309187.jpg


The 516 likes the heavy bullets...work up some 77grain Nosler custom comps. Again, @ 100 yards with the 1-4 Vortex (measured. 83 inch), that's under 1 MOA. Very happy with that! This 516 is tempting me to bolt a target scope to it.uploadfromtaptalk1374638762822.jpg

Here is some from my 716...I'm not happy with it yet. Shot 4 and 5 from a 5 shot group are consistent flyers. It's either barrel heating or Reloader 15 getting warm while I'm settling in. I am switching to Varget this weekend, hopefully that will net better results. uploadfromtaptalk1374639126960.jpguploadfromtaptalk1374639146410.jpg

I usually use these 200 yard bench rest targets for load development, there are 6 bulls eyes on each sheet and they're easy to write on and cut out for record keeping. I'm always open to suggestions and input.

Thanks for the input, Dave!

I really wish I had the...

...INFRASTRUCTURE to back a reloading hobby.

Apartments simply aren't ideal!

Question for the OP. Was the match trigger a "drop in" type? Also, did it make a noticable difference in break and reset?

I'm looking into triggers for my 516 and 716.

The Geissele Triggers?

They're a nice, crisp luxury of sorts - but in retrospect, with the type of horsing around that I do, I should probably have stuck to the factory triggers.

Look at their website, they've got excellent how - to videos.

I'm at work right now, punching this in really quickly...

But there ARE official Geissele instruction videos that are YouTube - based.

I installed them before having ever fired any shots in my entire life.

If I can do it, so can you

Thanks for the reply. I will do it. 1st, tomorrow, I'm going out for a 2nd function check, with eotech/716. If all goes well, I'll be installing a match. I had a wilson match trigger on a Dany Defense for a couple of years, and it DID make a difference, of approx. a half an inch at 100. Not a lot, but worth it IMO.

I guess I'm kinda like you in that I have no commando fanticies, and I just enjoy shooting high quality guns. I do however consider my police/military type guns, "just in case ****" guns. Hopefully/probably they will never be needed for that role, but anything is possable.

I live out in the boonies and my driveway is about 200 yards from mailbox to house. If I can keep shots inside a 4 inch circle, in a reliable, durable semi auto, I'm fat and happy. Durability/reliability, are always 1st for me. Usually if the shot is off, it's my fault not the guns.

I like knowing, especially after the recent gun ban scare, that if the govt. figures a way to ban the good stuff, the guns I own will outlast me.

From EricTheOracle: SIG 516, Burris Eliminator II 4x12-42

100 yards



200 yards



300 yards



400 yards



Points of interest.

1) As the barrel warms up, shot groups dramatically open up. After 20 rounds go eat a sandwich to let things cool down. A heavy barrel is needed for longer ranges.

2) At 200 yards, the shooter can see the holes in their own targets but at 300 yards and beyond, a spotter is needed.

3) There are no hash marks on the reticle of the Burris Eliminator 2. I found this totally annoying trying to judge windage, and for that matter, after the holdover timed out. This isn't a scope you want to take into combat where you may be holding on a target waiting for the call to fire because you'd quickly run the battery and your sanity down refreshing the range to get the holdover to light up over and over again. windage and elevation hashmarks would be a welcome addition. Without those hashmarks, I don't think I'd buy this scope again. Nevertheless, the ranging and holdover all work as advertised and the scope is fun to shoot (until, that is, the barrel on your Sig 516 warms up and shotgroups go on a walkabout).

4) I've yet to try the automatic inclination and declination (shooting up and down hills at targets) features of the scope.

5) Inconsistencies in accuracy between the 300 and 400 yard targets are attributed in my mind due to wind gusts which were blowing my slight picture up and down and my lack of discipline to hold fire.

Like a beautiful woman with one serious character flaw...I cannot make a solid MOA shooter out of my particular 716 so, I'm going to break it off with her. She is beautiful and she turns heads at the range but, I just can't love her. I've tried 6 different bullets and 4 different powders. I even broke down and tried some m118 today. I've even posted that I would eventually get the magic combination... I believe I've put my foot in my mouth. I usually only post the best groups but, the reality at the range today has me thinking it's time to move on.

uploadfromtaptalk1376266285687.jpg

The bottom 2 are from today, the wind was only 5mph so, I can't even blame it on range conditions.

uploadfromtaptalk1376266415723.jpg

The top 2 are the very best I've been able to get out of it. 2 MOA is not acceptable (for me) from a $2k rifle and I am not crazy about the 300Win-mag beating I get with this .308. I'm planning to sell it locally and recoup enough money to get another ADM mount to run that Vortex on my 516 and be able to switch between 1-4 and 4-16 Scopes depending on what I'm shooting without loosing my zero. And, picking up a new Nightforce for my Savage.

Here's how a $2k rifle should shoot and, this one is 100% reliable.

I hear ya Dave. Big thanks for the rangę report.

Its so very,very hard to beat a Savage for out the box trigger and accuracy.

The fcp-śr I had was just wonderful in every aspect.

Im now hoping to get a Long Rangę Precision in 6.5 Creedmoor.

Its soooo easy to get hooked on long rangę shooting.

Too many fine toys and not enough dough......Ill swear fellas....
