View Full Version : SR25 EM carbine range report and data
It finally stopped raining long enough for me to get out to my land and get some distance shooting in.
SR25 Em Carbine with TA11H-308 with BDC set for M240:
Weight: 9lbs 3.5oz without ACOG. 10lbs 3.8oz with ACOG
First I set out to Chrono the gun and confirm zero at 200m, I had previously zeroed at 100m with a holdover.
Zero was done with Blackhills 175gr
Chrono was done on blackhills 175gr and PVRI 175gr using 9 rounds of each.
Atmospheric data at time of chrono: Temp 66, Pressure 30.00, Humidity 38%.
Black hills 175: Average 2560fps, High: 2622 Low: 2540
PVRI 175: Average 2559fps, High: 2599 Low: 2501
After that I fired at 600m 500m 400m 300m on steel IPSC style target to confirm BDC. All matched up perfect.
I achieved a first round hit at 600m using the BDC, and was able to hit every shot out of 10 fired off the bipod. Pretty happy with those results. I did a variety of positions and some shooting and moving and quick double trap drills, gun worked great through all of it. Recoil isnt bad and its easy to get back on target quickly.
Rounds fired
200 Pvri 175
19 Blackhills 175
40 M80 ball lake city
20 Win 147 ball
Malfunctions: 0
It had previously not cycled well with PVRI, but for whatever reason it now works fine with it. Guess it just had to get worked in.
I love this gun.

200m zero target, I bet the gun can shoot better than this, but with me and 3.5x scope, I dont think this is bad.

Great range report. I'm taking my EMC back out this weekend to see if I've sorted some of the failure to feed issues (most likely due to underpowered ammo and not lubing it well enough before the range trip).
Thanks Rusted.

Thanks for the RR.
I am seriously considering buying one of these, but for 5K I would not expect ANY failure to feed issues? Both of you have had this with the new carbine?? Maybe even KAC has not worked out all of the kinks of the .308 AR platform???
Every gun needs a little adjustment period when it's new. If it didn't start running 100% after 500 rounds then I'd worry.

It could have just been a bad box of PVRI when it had the failures, who knows. That PVRI also wasnt running my AR10 at all.
The SR25 now works 100% with any ammo, with both PMAGs and the mag it came with. It runs smooth and perfect.
It runs better than I expected, and has exceeded everything I wanted out of it.
If I could buy again I would.
Bad Ass Boom Stick.
Thanks for the report and pics man.
Nice post RA... some sweet stuff right there :cool:
Is the 9 lbs 6.5 oz with a loaded mag? I ask because they're advertised as 8.5 lbs empty.
It's heavier than 8.5 from what I've found. ;)

9lbs 3.5oz unloaded without ACOG
Sorry, I entered it wrong when I first typed it up.
I was told 8.95lbs as the weight when I bought it. So the weight makes sense with what I have added.

Even w/ variable optic & mount still lighter than MK14 Mod 1 / Mod 0 or FAL w/ same.

Not to bogart RA's thread. But I ran about 100+ rounds of Remington 150gr Softpoint out of the SR-25 EMC, and it functioned FLAWLESSLY. I'd say a combination of lack of full field strip/cleaning before firing, and some bad ammo caused a butt ton of failure to feeds last time.
This time...oh man. I need to do my AAR.
As an anecdote, there were 2 guys at the range with EMCs as well, one of the guys had the serial number one digit after mine. The shame was these two older gentlemen had purchased the rifles and only intended on using them for bench shooting. It absolutely made me sick to my stomach. This is a rifle that's meant to be used for run and gun, to really stretch its legs. Get a bolt gun otherwise. So sad. :(
I've owned and shot a half dozen AR-pattern .308s, including a LWRCi REPR and LaRue OBR. The thing that really stood out for me on my first range day with the EMC was the recoil, or lack of it. The gas system is so finely tuned that felt recoil is greatly mitigated. It's kind of hard to describe - more of a gentle push as opposed to the sharp smack that my AR10A4C gives me (Noveske 14.5" N6 barrel). I can imagine that an EMC with a triple tap muzzle device would simply not move when fired...
I had no failures of any kind shooting off a bipod and offhand, using LR20 mags, Hornady TAP 168gr Amax, and DAG 150gr mil surplus.
As RustedAce states, this rifle is flat out amazing.
ETA: chrono MVs (45degF, 35% humidity, 900' ASL):
Hornady TAP 168gr Amax: 2424fps
DAG 150gr mil surplus: 2518fps
Hey guys! Sorry to ask this in 2 threads but I am ready to buy but having trouble finding a reputable dealer to buy from. A place with no CC fee's would be great but is I supposed best price for a NIB wins. :o
Anyway's thanks for any help guys!! Also thanks for the range report! I am primarily interested because of how light the carbine is comparatively.
nice report and nice stick.
Range report from today.
Rounds shot: 60 BH 175: chrono: 2548fps average
20 Fed 168 chrono: 2527fps average
Shot 20 BH at 400m and 20 BH at 500m both at a 6inch gong.
Hit 20/20 at 400m and 18/20 at 500m
Last 20 BH went into checking BDC at 600m, was an 8in group 5in low, which is where bulletflight said it should be.
THIS GUN IS OUTSTANDING! I am in love.:D

But seriously, you think about the 6x Acog for this gun? I know the 6x is a big beast but dont you think it lends itself better than the ta11?

I keep returning to this thread to get my .308 fix until my MRP comes in. Beautiful stick.

Never played with the 6x ones in person, so cant really say.
I am happy with the TA11, I can still hold a great group with it out to 600m, I wouldnt mind more magnification, just wouldnt want to get more magnification for the cost of more weight.
I am trying to keep mine more of a general purpose rifle than a dedicated long range one.
My future plans for the rifle involve getting the suppressor for it when it comes out, then zeroing my thermal scope to it, so if I can only bring one gun, I can bring this and basically do anything at any range at any time.:cool:
I say get the 6x one and let us know how it turns out!:D
As for the diddybag, yup, its been doing range bag duty ever since I got out.
7.62 NATO, turning cover into concealment since 1957. :cool:

Thats really what I look for when I read about new guns, the raw data about stuff, so I figured I bothered to get all that data, might as well put it out there for potential buyers.

I will be shooting ball and 155gr TAP, but I think it should be close enough for what I want to do. Have you checked the BDC with ball?
ETA: where did you get it, and was it in stock?

What I did was plug the velocity and bullet weight into a ballistic calculator and match up the zero to it.
The TA11H-308 is calibrated to 147gr at 2800 fps.
So all I did was change my zero point to where the ballistic calculator said all the drop lines would wind up the closest. Which happened to be 175m for the 175gr.
I then shot it at 100, 200, 300, 400, 500, 600. and it matched up perfect. I wish I could test it out a bit farther, but I trust the calculations because they were spot on out to 6.
What you could also do is get your muzzle velocity for the 155 out of your gun first, then buy the ACOG that has the closest BDC to it.
I got the ACOG through botach during thier 15% off sale, I know people hate botach, but I have had good luck.

Where did you get the chart that shows the reticle drop figures for each stadia line?

I emailed trijicon and asked them what they used to calibrate the TA11h-308.
Then plugged the muzzle velocity and bullet data they gave me into a ballistic calculator.

Any chance I could ask you to do that for me so I don't have to do the whole process over again? (run the chart and predict a zero for a couple of specific loads, that is?)

Yeah man no problem, I would just need the velocity for the 147 and 155 out of the LMT.

OK - if you would, figure 2550 for both of them (M80 ball and 155gr AMAX). I will actually go out and chronograph them this weekend, but I would like to get an idea before then, and I suspect those are going to be pretty damn close.
Here is some info for you, range in meters, drop in MOA:

900: -48.4
1000: -60.3
1100: -73.6
1200: -88.5
Messing around with other zero options it doesnt look like its very easy to match up the 147 out of a 16 barrel to the TA11h-308, you might actually be better off with another ACOG/ or another heavier round, they have TA11s calibrated for both 5.56 and 168 .308s, I dont remember which ones though, but one of those might match up better to the velocity/weight.
I would recommend downloading a ballistic calc or if you have Iphone getting bulletflight or ballistic, both are really good.
Oh, this is useful too:

Thank you! How does the 155 TAP look?
ETA: I just talked to someone at Trijicon, and they said that the TA11H-308 is supposed to be zeroed at 200. That would probably make the numbers look different.
ETA again: what program are you using? I'll get it and get to work on it myself.

Yeah, thats the one mine has in it. My understanding is that the MOA measurements in the picture are correct for the TA11h as well.
I used bulletflight to get that data, it works good, ballistic also works well, both are for Iphone, there are a few free online ones around as well, but I dont remember thier names.
Trijicon told you 200m? The trijicon rep on TOS told me that the H versions were supposed to be zeroed at 100m. Weird. They really need to include all this data in the manual.

I talked to Dawn at Trijicon and she told me that the zero point is the dot at 200m for the H version, the tip of the chevron at 100 for the -F version, and the top of the donut at 100 for the -C version.
I don't have an iphone, so no joy on that.
The M110 Episode was on "Tactical Arms" last night and on again tonight at 10:30. The SR25 EM Carbine that LAV was using in part of the episode was pretty sweet. I've got the Tivo set this time.

Hey Titleist or RustedAce will a UBR work on a SR-25? Ive never seens pictures of one with a UBR stock on it. Thank for any info
You can install them but you'll have to muck with the spring and buffer since the buffer tube is specific to the SR-25s. So to make it work you have to install a new spring and weighted buffer (equal to the original).
I'm sure it makes a good result, though for my money I think the Magpul ACS is still the best upgrade.
Rwatts62081
08-02-10, 12:11
Thanks for the response. We need more pictures of these SR-25s!! Im going to order one probably next month. Trying to decide what optic to put on it. Either the NF 1-4x24 or Acog 3.5x with horseshoe reticle. Any opinions?
Rwatts62081
08-02-10, 12:18
Well, those are nice but I want some magnification. Other items going on it will be a OD green UBR, OD green MIAD, OD green AFG, and OD green ladder rail covers. Already have 7 Pmag 20LR's, 1 CP 20 round mag and 1 KAC mag. And probably puting a AAC brake on it.
FYI AAC doesn't make a compatible brake for the SR-25's threading. Also ditch the KAC and CP mag (The CP is garbage), and just get more LR20s.
Also I'd be real hesitant about swapping out the stock to the UBR, I've seen SR-25s get wiggy when not running with their factory buffer setup, everything is tuned a certain way for a reason.
Rwatts62081
08-02-10, 12:33
Who makes brakes for SR-25s? Other than KAC? And I will be getting ALOT more 20LRs and ammo. Already have over 700 rounds in 7.62 in combination of 147 FMJs, M118LR and TAP.

At this point you've only got two choices, one of which isn't out yet.
The KAC Super Tap, or the Battle Comp BABC. Surefire makes a brake, but it requires 2+ inches of barrel to slip over, which the EMC does not have enough to work with.
Rwatts62081
08-02-10, 12:52
Alright Ill put a BattleComp on it, and a OD green ACS. Would the mil-spec or commercial model work?
Milspec. KAC's stuff is all milspec tubbage!
