View Full Version : Show your 10 shot groups

Starting a thread to show your groups. As mentioned elsewhere, a 10 shot group better reveals the capability of your rifle, ammo, and skill set than small groups. We all have room for improvement. Too many internet commandos fake their results and otherwise set unrealistic expectations. Let this thread be a place for feedback and support in precision with your AR.

I’ll start.

Worked on some recipes today with 8208XBR and 77gr SMK. Best group at 100yds was IMR max load. Strangely, none of these fully cycled the round. Maybe because it was 25*. I saw zero signs of pressure and will work up from here.

Made 10 rounds of 4 loads (some didn’t seat well so I chose not to fire them).

Rifle: WEVO tribute rifle. Mega with proof barrel.

75gr Gold Dot. Used a suppressed 16.1" DDM4 gov profile barrel factory rifle from DD. I was using a 4x Nightforce, shot it with the rail rested on a sand bag. Oh hell, here's a video:

Nice!

Fledge - nice rifle..whatever load is in the bottom right corner , it likes.

Jgifford- That’s a nice little range to have to shoot at..and all alone..sweet..nothing but pits around here..lol..

I’m gonna have to get in on this..

That's the local WMA range. I no-longer go there, as I have my own range at the house, now. Pictured below is 30m, and 85m. It goes back about 125m, and I have since the photo was taken had all of the trees trimmed to above head-level so as not to obstruct the targets. This is part of what I've been busy with and hence my absence. I worked quite a bit to snag the downpayment to add this 7 acres of waterfront property to my estate.

JG, beautiful range! How about some waterfront pics. :)

Mustang, the bottom left is max charge in the book. I’ll be adding some more to see if it improves even better. Strangely, I can’t get the rifle to cycle with this. It cycled fine with similar forums in TAC. Similar outside temperatures too. Maybe a faster charge will improve that too. Or a lighter buffer.

Fledge I know people love 8208 but I can’t get the results from it. Even at near max-max loads, there is a significantly dampened amount of recoil and the brass just falls out of the chamber it feels like compared to other powders (CFE, RE15, Varget, etc). The only decent groups I’ve gotten are much slower than my standard go to loads

That’s helpful!! That’s my experience yesterday. At least it was grouping decent. I’ll up the grains and see what’s next. I plan to try RE15 next.

JG, beautiful. Are there fish in those waters?

Max load , and your adding more..work slow.

Also when it warms up it’s gonna show you different , as you know. I never ended up towards max as I usually hit a node low and higher in the powder range. But since I was just plinking paper and targets I usually settled on the lower charge ,where it worked a 100% and ran the gun flawless Only time I’ve been towards max and settled there for some lots. Was 77grs and Tac.

But I never have really had the time or range to sit down at, I’m always up in the hills somewhere...lol..there just isn’t crap for ranges out here , one within an hour and it sux at best..old and rundown..blah blah..anyways..

My favorite 2 powders were Tac and AA2230. Stellar results with the aa..It was just hard to find years ago..So always back and forth with Tac and H335 which is also a good ball powder I had decent results with..

Try out some 69gr’ers.. every “match” barrel and decent that I had all loved them, almost better then 77’s..

I’ll get in on this, just need to find some time to hit the one range around here, about an hour away... Haven’t really sat down and shot/grouped some ammo thru the battlekitty..really only sighted it in, up in the hills.. Not the best barrel, but the BA 223 wlyde barrel showed a decent sign of maybe being a decent shooter..

Question for the veterans: I notice my bullet seater puts a ring halfway down the bullet. Dillon die. What can I do to prevent this?

Is it more than just grime that can be wiped off? I'd expect it to just be a dirty die.

I’ll check that out! It was much more pronounced on the Nosler than the Sierra.

mustangfreek

27 January 2019, 07:07

Probably just the die and different bullet profile leaving its mark..shouldn’t do much of anything if it’s just a light mark.

Have you tried any with a hair shorter OAL? I seemed to have my best luck around 2.245

That Hornady group is pretty good

fledge

27 January 2019, 09:22

I did find rings of brass shavings in the die. Hope that’s the problem. I’d like the bullet to stay as perfect as possible.

I’ll try that case length, mustang. I’m also going to try these recipes in a SMOS barrel. My SMOS has always been more consistent than my Proof with factory ammo.

There are several different kinds and brands of seating stems. Sometimes the stems need to be modified when loading up extra long ultra high BC bullets.

If the little ring bothers you I would get a few seating stems. They are generally not expensive.

2.260” OAL? 2.6” is long

As far as the ring on the bullets, the seater plug is doing that. You can clean the plug then polish the inside of the stem where it contacts the bullet. More here:

http://bulletin.accurateshooter.com/2017/04/polish-inside-of-seating-stems-to-avoid-ring-marks-on-bullets/

RCBS will make you a few custom stems if you send them the bullets you use they’ll send back custom stems shaped for your bullets

Yep. A few companies do it. If I ever win the power ball and can start loading ultra high BC all copper bullets all the time I would have a few extra seating stems around.

Got my first range day of the year. MDT's Black Friday sale allowed my best group ever for my Savage 12. What a difference a chassis makes. Also, my rifle like lighter bullets. I never had instability with 69 grain Nosler CC, but they never grouped well. This 10 shot group is better than any 5 shot group I've ever recorded, plus I just picked a load out of my guide, no workup.

Is the tip deforming? I had some seating rings on a recent load. At first I thought the problem was because I was using flat base buckets, but then I added a little extra chamfer to the brass and they seated beautifully.

This picture/group is a few years old and I'm pretty sure I've done better with the Federal XM68GD 90gr Gold Dots and about the same with the 115gr Fusions. I haven't really worked up a hand load for my 6.8 and now have a 12.5" ARP that I probably only have ~100 rounds through so really haven't put it through it's paces yet. I just put a new Vortex Razor HD LH on my 16" 6.8 so hopefully I'll make some progress on 6.8 load development this year.

I hold the ARP barrels to be one of the best values in the AR barrel world. It's also why I refuse to create an account an TOS as they'll ban you for even mentioning the name of the company because they value power trips and holding a grudge more than educating the community and the truth.

I wanted to use the Strike Eagle and factory ammo (CBC/Magtech 77gr OTM) with my Ultramatch barrel to see what someone could do with off the shelf components. My groups opened up a tad at 200 and 300 but it’s definitely capable of putting rounds where you want them.

Well I haven't shot this Ar15 in quite awhile due to my dabbling in the 224 Valkyrie arena. So I took her out to MRC today and realized I had forgot what a damn tack driver she is. The three groups below are all at 100 yards. The first group was with some factory 77gr Magtech rounds and the last two groups were shot with factory IMI 77gr Razor Core. Color me impressed! It's a Mega Monolithic rifle, 16" FN barrel with a Vortex Strike Eagle 1-6X mounted. The reticle pretty much covered my point of aim so I could possibly do better with some proper glass.

No.

I read on here from somebody that 4 moa is chest width at 100 yds.

4 MOA at 100 yards is 4.19 inches.

Precision Shooting With an Aimpoint: Range Report

First and foremost, the Aimpoint red dot sight is a combat sight. Its primary purpose is for use in situations that require “reflexive shooting” at multiple targets, at close ranges. The Aimpoint excels in this type of shooting because it easily allows you to shoot with both eyes open and to focus on the target while shooting. All of my self-defense AR-15s have Aimpoints mounted on them. However, should the need arise (for example, making a head-shot on an aggressor at 100 yards who has most of his body behind hard cover) the Aimpoint sight is certainly up to the task of making precision shots.

There are those who claim that when using an Aimpoint sight with a four minute of angle dot, that it is not possible to shoot groups that are smaller than four minutes of angle in extreme spread. One such person has gone so far as to claim that groups shot from 100 yards using an Aimpoint with a 4 MOA dot will be “greater than 4 inches. Usually much greater.” As we shall soon see, such statements are completely false.

To determine the level of precision obtainable when using an Aimpoint sight with a 4 MOA dot, I mounted an Aimpoint ML2 with a 4 MOA dot on one of my Krieger barreled AR-15s. This AR-15 is easily capable of producing consistent sub-MOA 10-shot groups at 100 yards when using a high magnification scope. Shooting with the Aimpoint sight was done from a bench-rest at a distance of 100 yards using NRA 200 yard High Power type targets that I scaled-down for 100 yards. (The aiming black is approximately the same width as a human head.) Sighting was done using the whole dot centered on the bullseye. Three 10-shot groups were fired in a row for evaluation.

https://www.ar15.com/media/mediaFiles/28568/aimpoint_comp_on_rifle_01-1255869.jpg

Zeroing the Aimpoint sight at 100 yards was conducted during a down-pour with 20-25 mph winds. The first two 10-shot groups were also fired under these conditions. The first 10-shot group had an extreme spread of 1.41”.

With another couple clicks of windage and elevation adjustment, the second 10-shot group had all shots going into the X-ring. The extreme spread for this group was 1.19”.

Just as quickly as the down-pour had started, the rain stopped, the winds died down and the sun began shining again. I posted a new and dry target on the 100 yard backer and continued shooting. The third 10-shot group had an extreme spread of 1.14”. The average extreme spread for all three of the 10-shot groups was 1.25”.

Fantastic shooting. I can’t see a target well enough at 100yds to make groups that tight no matter the size of the dot.

What about a 100 round group?

Savage 110 Elite Precision, 6mm Creedmoor
108 gr Berger Boat Tail Target, Alpha new brass, 2.260 CBTO (~2.8 COL), 40.6gr of H4350, BR#4

That load gave me about 3,130 fps, temp was 64F. I think I'm about 400 rounds into the barrel and that load has picked up around 100 FPS as the barrel has broken in. I'm going to try backing down the load a bit to get it under 3,000 fps in hopes of extending the barrel life.

Swapped out the model of my Vortex Razor 3-18x50 from EBR-2C (MOA) to EBR-7C (MIL) so if I ever make it to a PRS shoot I won't be "that guy" talking MOA. Christmas tree reticles make zeroing a breeze since you can reed your adjustments directly off the reticle.

3-shot group at 100 yards to confirm zero (sub .5 MOA):

10-shot group at 100 yards with MagnetoSpeed to get velocity data, hence POI shift (a little under 1.5 MOA total, or sub 1 MOA if you toss the flier, about .7 on the vertical stringing):

4-shots at 350 yards (2.5 inches, so a little better than 3/4 MOA - I broke my position between shots and I may have put a bit of cant in there) :

Nothing super impressive for a competition shooter, but for a factory gun I'm happy with it's accuracy. If I can fix it's ejection issues (it tends to leave the spent case sitting on top of the next round in the mag but facing backwards) then I'll be comfortable taking it to a match.

Bolt, 100y, 4 of them are with elevated HR under a generous time constraint as part of a qual.

That’s helpful!! That’s my experience yesterday. At least it was grouping decent. I’ll up the grains and see what’s next. I plan to try RE15 next.
