308 AR10 Groups, et al

[Tomcat]

Here are groups from my collection of 308 autoloaders, at 100 yds.


ALL ARE 5 SHOT GROUPS, shot on same day

Here is a group from my 20" REPR
168 Grain FMMM

This is from a 18" REPR

and another, same REPR 18"

This is 5 shots from a GAP Crusadaer - 168 FGMM.

Re: 308 AR10 Groups, et al

Next weekend I will shoot my GAP10 and post results. What I have so far on the GAP10 are not that good, and really not worthy of posting, they are about 1.5 inch groups.

 

[BOL556]

Re: 308 AR10 Groups, et al

Looks good. From what I have seen every post about the REPR is it prefers the 175's but looks like that changed. Was thinking about getting one which started a roughly six month search of what people were thinking about them and what kind of groups they were getting.

 

[darthceadus]

Re: 308 AR10 Groups, et al

I have no problems with my gap-10, its a solid 1/2" gun all day. Also 2 out of 5 groups are 3/8" moa all day. The gun is apart getting a new hand guard or I would shoot 5 groups of 5 rounds. I could send you a couple pictures but don't know how to post them.

Re: 308 AR10 Groups, et al

Shot these last Thursday

Need more practice with the AR

USAammo 175 SMK's. Got to 6 rounds and started over

USAammo 175 SMK's. Got to 6 rounds and started over haha

FGMM 168's

I struggled with a few things. 1st was consistency with the loading of the bipod. 2nd was cheek weld and paralax. 3rd 4th 5th and 6th was that by the time I shot the 10 round group, I was pissed from poor shooting, the barrel was good and hot and I shot it as it was getting dark. I shot it quick too. I'd say one round every 3 seconds. I need to work on my large AR and bipod-fu. Just not quite used to the extra effort it takes to "run" the gun. I will be a better shooter because of it though.

On top of a hot ass barrel that was the first 10 shot group I have attempted.

I think all of my fundamentals were off on the 10 shot. Trigger control and straight back pull. Cheek weld consistency, consistency of bipod load, breathing and follow through.

If I think of any more excuses I'll be sure to edit this...

I'll have to post some more groups in here when I get some more time on my P308. I will tighten them up for sure. Looking forward to the 200 rounds of Southwest ammunition 175 SMK's from the group buy that should be here soon.

Almost done paying off the G2 HDMR too, that will be nice.

Re: 308 AR10 Groups, et al

Like this thread a lot, thanks for posting this up for us. I had a 16 inch REPR that shot nice groups at 100 yards.

 

[lennyo3034]

Re: 308 AR10 Groups, et al

Appreciate posting the whole sheet with ALL the groups on it, instead of just the best ones. I admit I've been guilty of this in the past.

Re: 308 AR10 Groups, et al

Sithlord, PM me when you get it back together, if you email em to me, I'll post them.

 

[Tomcat]

Re: 308 AR10 Groups, et al

Reddirt - I think thats pretty good shooting. You have a vertical string in there, to me that means you changed your head position a little lower each shot. But you held really good horizontally.
In your group number 2, I see that one flyer all the time from my guns. I get a really good group and one shot goes off to the side, definitely not where I called it.

I think this has to do with the barrel heating up, though I'm not sure yet.

gotta be a joke right?

 

[B.Morgan]

Re: 308 AR10 Groups, et al

Tomcat....If your getting 1.5" groups with anything from GAP, I would send it back. I have a few Gap10's and if I get .5" groups I am disappointed with my shooting because the gun will do better. All of mine shoot very well and they are by far the best gasser I have owned.

The platform takes some getting used to as compared to a bolt gun but the gun will shoot. If your confidant that it's not you, have another good shooter try and if it's still not where it should be then send it to GAP.

 

[LineofDeparture]

Re: 308 AR10 Groups, et al

Gap10 18inch
This is a 5shot group @100, she shot 1.5 inch groups until i figured out what I WAS DOING WRONG... Then this was the norm...At first I thought it was the gun, but I figured out what I was doing wrong...and I think the rifle will shoot better. I'm just getting the feel of an AR-10..

</div></div>Thanks. I shot all three groups in the matter of about 20 minutes so I know the barrel was hot, especially by the 10 group. I will slow down, concentrate better on form and take a few more guns to keep me busy between strings next time.

Are you holding the trigger back all the way through recoil, and loading up the bipod every time? You have to follow through on these things -my SASS didn't start shooting sub-moa until I focused on trigger control all the way through the shot. I don't reset the trigger until my crosshairs are back on target again.

 

[Tomcat]

Re: 308 AR10 Groups, et al

Here is are 6 five shot groups, done with a GAP10 and Federal Gold Medal Match 168.
This gun didn't like my 175 grain reloads as much. My Crusader shoots 3/8 groups with the 175 reloads, but the GAP10 dosnt even come close at about 1.5 inches.
I am going to use my FGMM recipe in a week and see how it likes that.
Note group 3 is about 3/4 inch. The rest are about 1.1 or so.
My question is:
IS THIS A 3/4" GUN?

 

[Alien61]

Re: 308 AR10 Groups, et al

Remington R-25 20"
Berger 175BTLR N150 Fed210

100m 7 rounds

300m 5 rounds

100m 5 rounds

but when im loading really hot its going like that.)

</div></div>It may be a 3/4" gun, but I doubt it. Some days I think my GAP-10 is a 3/4" gun, but then I concentrate on the fundamentals and it becomes a 3/8" or better gun.

Those groups are showing me that its you and not the gun. You have several shots in those groups that are touching and then the spread. The two that are touching you did everything right. The others you changed something.

These gas guns are much harder to shoot than a bolt. The mind set is "the gun went off and I shouldn't have to do anything else". Not true, follow through is so important when shooting gas guns.

Re: 308 AR10 Groups, et al

I have been working on my DPSM SASS a lot this month month, I determined due to the short barrel, i was going to concentrate on getting it to be an accurate 600yard gun, and use my overly abundent supply of SMK168s.
The best load I have ever found is 43.1 RL15 at 2.81" in Win Cases. This was only 3 shots, but when I loaded up 10 more, it showed the same sub MOA grouping, and was right around 2445 FPS

Another good group is 43.5 Varget with 168SMK 2.81" Win Case, even with the one weird flyer, it was still sub MOA, take away the Flyer, and its a 0.3" group

Shooting a Auto is very very different as mentioned above, takes more practice. If I can stay in the sub MOA range, i am happy with it cause its fun to shoot.

 

[BCP]

Re: 308 AR10 Groups, et al

My 308 AR is sub-moa with good ammunition. Me, not so much. If I can keep 5 rounds in an 1.5" sticky @ 100 most of the time I'm happy and if they're less than an inch center-to-center I'm ecstatic.

Ammunition consistency, scope (higher powered scopes with fine crosshairs and parallax adj > lower powered, thick reticuled ones for target shooting), the kind of rest you are working with all play a huge part in accuracy.

Should be going to the range this afternoon so I'll have something to contribute.

win brass, cci primer, 43.5 varget, 178amax @ 2.78COAL was silly accurate in mine and around 2450fps.

ARMALITE AR-10A4 Chrome-Lined built by Richard Clancey of ARMALITE:

Using this set-up {diff rifle in pic}:

This was done during the last 30-45min of daylight the evening before Bambi Bashing Day:

I also don't believe that precision {heavy} gas guns drive differently than bolt guns... within reason. i.e. bipods are tactical & practical, rests are for groups.

EDIT: gave three clicks right and went home

EDIT II: That was either Hornady 150gr SST Custom Classic

or

Georgia Arms 165gr NBT Precision Plus AND YES...

it was done with the AIMPOINT 5000 1.5MOA dot

Re: 308 AR10 Groups, et al

A few times lately I have thought I heard the big brown truck creeping up the driveway with my 200 rounds of SW 175's... No go

Will get more time behind the P308 and post some more (better) groups when it does come.

Re: 308 AR10 Groups, et al

I have an OBR on my "soon list". Decided to get one based on everything I have read about it here on The Hide.

Re: 308 AR10 Groups, et al

For those of you having trouble with AR 10 in 308 try shooting prone. I feel the prone position puts you better control of the rifle. I have a very difficult time shooting from a bench with the 308 ars.

 

[Cornholeo]

Re: 308 AR10 Groups, et al

GAP 10, 18" barrel, 100 yards from a bench, 175SMK handloads. As soon as the grand babies are safely back home next week I'm heading to the range to start practicing what SH online training is teaching me, or trying to I mean.

Damn good shooting, what is your load with 175SMK's?

 

[Cornholeo]

Re: 308 AR10 Groups, et al

Lapua brass
Sierra 175Gr.matchking
CCI BR2 primer
42gr IMR4064

I cannot take the credit for pulling the trigger on this group, this was my buddy who reloads for me. He said it was the best shooting semi he had ever got behind. I am really looking forward to applying the hide training on this gun, in particular the training on gas guns that they put together. We noticed a pulled round on the last round quite a bit, which is what Lowlight talked about in training.
Got the gun,got the ammo, getting the training, gonna make some time to get behind this girl and shoot.

 

[redirt78]

Re: 308 AR10 Groups, et al

Wow.

Well, you will definitely know it's you and not the gun if your groups aren't tight.
Seems like all GAPs are shooters but that is one hell of a ten shot group for any gun (assuming it's 10 shots)

How many loads did he try before going with this one? I hope my gun and I can get results like that when I get better. Right now I don't know its potential

 

[Cornholeo]

Re: 308 AR10 Groups, et al

It was a 6 shot group, last shot pulled lower right on him. We tried 3 with RL15, 3 with Varget and 3 with the IMR. One group with RL15 was pretty good best I can remember.

 

[redirt78]

Re: 308 AR10 Groups, et al

Looks like you're onto something with the batch in the picture.

UPS man dropped these off today from SW.

Just need to get out and shoot now.

Re: 308 AR10 Groups, et al

Sweet! I have seen several posts around the hide of people using southwest ammo with great results. Let us know what you get out of her and what load @ Southwest you bought.

They are the <span style="font-weight: bold"><span style="color: #CC0000">SWammo 308 Match 175's</span></span> <--Link

New Manufactured 308 Match
Ideal for both bolt and semi-auto rifles.
-FC military brass
-Very temperature stable powder. More consistent velocity from -40 to 160 degrees.
-175 grain Sierra Matchking
-2650 fps from a 24" barrel

I got in on their last group buy. $175 for 200 rounds. From what I hear, you cannot beat the performance for the price. Especially that group buy price.

I don't have any reloading gear so the lower cost military brass is fine by me.

This weekend has/will be busy so no shooting yet. I will see what I can do with them and post some pics.

Re: 308 AR10 Groups, et al

My current groups with the GAP10.
These are with 168 Federal Gold Medal Match

all are 1' and under.

 

[T2CH]

Re: 308 AR10 Groups, et al

Nice groups Tomcat.

My GAP 10 will shoot one hole groups with those rounds, when I do everything right that is. My biggest problem is the follow through with the trigger. I don't always hear the trigger reset and thats my check to get it right. I slow down and make sure I hear it reset, everytime.

Re: 308 AR10 Groups, et al

I have shot several 5 shot groups like these out my stock AR-10T, while not the norm but it's not unusal either...

 

[Tomcat]

Re: 308 AR10 Groups, et al

to all -

Please post multiple groups on one page. The idea is not to showcase the best group of the day/month/year, but to illustrate consistent accuracy on demand.

6 groups on one page.

Here ya go. Bottom left and middle are 5 shot groups, others are just three. Anything in the black was from shooting with irons before throwings the scope on. Who needs a bipod when you have a sling?

Whoops, is this the AR-10 only party?

Hi Guy,

You ever go through Stone Bay? I taught there in '85-'86. Some of you folks with M21s w/ART II scopes would borrow our M40A1s... not too many but atleast a few that hated the friction lock mount.

As noted, I live in Dallas, but work in East Marietta. If you ever want to shoot on the farm please let me know. The 2008 Dodge doesn't let us use the tailgate, too high. A WorkMate 425 bench and/or card table is what we use now.

I'm going a hundred miles an hour finishing multiple contracts for Motion Reality this weekend but will be free shortly. If the cows don't get in the way we can shoot 600yds at the front of the farm.

Best to you.

EDIT: We can go beyond 1K but that is on the backside of the property and almost always a pain except in the winter.

EDIT II: I only had less than 1 hour for sighting in. Sorry 'bout not having four (4) more targets for show-n-tell.
