Looks for Range

Looks for Range (1/11)

  1. Couple things to look at... first thing I would do is throw the stock recoil spring back in it and run a box of factory ammo through it. It that works, try a lighter recoil spring with you reloads - I run a #15 spring in my 9mm tac shooting 147's at 130 pf. If thats not it, check your fire control springs as mentioned above... wouldnt hurt to do a tear down and nice clean. Hope you get it running.
  2. Hey Nick - A little update after running this scope for a few months and a few thousand rounds... The short answer is... I LOVE that optic. Like I said in the original post, I have been through probably a dozen optic combos before I got the ACOG and finally settled on that. It took me a little practise to get used to running it on CQB courses but I would swear that I am just as fast with the ACOG now as I was with my Eotech. As far as the hold over stadia, I shoot 77gr MK262 Clone ammo pretty much exclusively so with the optic zeroed at 100, the holdovers are pretty damn close, they actually seem to be a bit generous past 300, meaning that I put the 400 yd stadia on the bottom of the human torsoe silhouette for center mass hits. I shoot weekly out to 600 without any issues at all. I have never really shot much distance with XM193 or M885 or any 55gr ammo so I cannot comment with certainty how the holdovers work on those but, what little I have shot with 55gr ammo has been pretty close. I had to show off to a friend who I took shooting last friday by going 10/10 on a steel human silouhette at 425 yards from a sitting position. Awesome!!! I have also had verified hits on a 16" diameter plate at 900 yards using the stadia in the optic. The glass is crystal clear, clicks are nice and firm, eye relief is more than generous, and it just works... no batteries... the optic is always there, ready to go. Hope that helps, it was an expensive purchase but one that I have absolutely 0 buyers remorse over. I am confident that the ACOG will outlast me. Cheers Shawn
  3. They are in stock at Larue, give em a call and have em check their inventory, they had 3 last time I checked.
  4. I zeroed the optic dead on at 100yards according to Trijicons website ( the top of the horseshoe ) and tested it at 200, 300 and 400 and it was adequate to make first round hits on the gongs and flashers I was shooting at. I threw it on my 20", checked the zero which was only slightly different and had the same experience. Soooo, in short, barrel length is a moot point for me. The quality, durability, optical clarity and reticle on that optic is outstanding, it is alotta money but I look at as an investment, absolutely no buyers remorse here. That being said, I did have serious buyers remorse after buying my Aimpoint comp M4, Eotech XPS2 and Leupold CQ/T, and I sold each and took a hit. I would have been $$$ ahead if I just sacked up and bought the ACOG first. Like they say... buy once, cry once. Hope that helps! gonna assume the above is a typo-if you zeroed a TA11H at 100 yds with the top of the horseshoe, there's no way you'll hit anything beyond about 200. zero it with the top of the dot at 100 meters. then, the dot holds perfect out to 250. after that, assuming your loads are matched to the BDC. the tree works for 300 meters and beyond. Correct, that is what I was meaning to say, thanks for catching that!!!! Was doing about 5 things at the same time as writing that post -->

  6. I have found the BDC on the TA11 to be dead nuts to the 55gr and 77gr ammo I load and shoot out of my 16" rifle. Had no trouble at all holding on the 400 yd hash and getting 4 / 4 hits on a man sized silhouette, your experience may vary. The ACOG is a battle optic so it is not necessarily designed for shooting MOA or tiny groups at distance, but for what it was designed for, it does a fantastic job.
  7. Davidwiz- I was looking at getting that cover, how is the quality?
  8. I received a couple PM's regarding this optic after a post I made a while back. The TA11 HG is the 3.5x35mm ACOG with the Green Horseshoe reticle with BDC out to 1k yards i believe. After I sighted in the optic on my 16" LaRue as per Trijicons instructions, I ran my first 3-gun match this last weekend. All I can say is I am impressed. We ran 3 rifle stages with targets ranging from 5 yards to 300 yards. I made all first round hits on all targets past 100 yards, and had no problem whatsoever quickly engaging close range targets for double-taps. Up close, if you focus on your target while keeping a good cheek weld, All i saw was a nice green horseshoe that I threw on center mass of the IDPA targets and squeezed off 2 rounds. Very very fast. I believe I was only down 3 points all day on the rifle courses. Best thing is no batteries! One guy had an aimpoint go down (dead battery in a comp m3) at the beginning of his run and had to switch to irons!!! The green reticle is easy to pickup, and the eye relief on the tA11 is more than adequate for run and gun type stuff. On the long targets, it felt like cheating. I was shooting MK262 clone ammo which already shoots sub moa out of that rifle, so making hits on silhouettes was cake. After going through an Aimpoint, Eotech, Leupold CQ/T... This is the optic!!!! I would urge anyone to check it out. I picked up mine from Larue Tactical which means it came with their bad ass quick release mount. They are not listed on their website so you have to call. Anymore questions, feel free to PM!
  9. Thanks for the response, looks like I will just have to man up and get it done!!
  10. Hey all- I just recieved a bunch of military processed brass, about 2000 pieces of mixed LC 07 and 08 headstamp brass. It came cleaned and the primer pockets were reamed to remove the crimp. I had read about a bunch of people who load bulk ammo for 3-gun and the like who didnt bother with much brass prep, eg. case trimming, chamfer, debur, flash hole ream / chamfer... I loaded approx. 100 rounds up with wolf 5.56 primers, 24 grs varget, seated to cannelure and crimped with dillon crimp die. I noticed that the case lengths varied so much that the seating depth in relation to the cannelure was different almost every time. This is when I started to trim the cases back to 1.75 I am using a forster classic trimmer and while it doesnt leave too bad of a burr on the outside or inside of the throat, I am wondering if is is necessary to chamfer / debur. I was afraid to chamfer because I didt want to take away the "edge" of the throat that woudl be crimped into the cannelure. Also, I figured the dillon crimp die would pretty much get rid of the outside burr. Ami wrong? Just trying to save a step. -SOCAL!
  11. ROUND 2! I loaded all the rounds in fully prepped 1x fired Lapua cases, trimed to 2.005, neck sized with a .336 redding comp busing die. Using Wolf primers, Varget, and 175 gr Sierra SMK's. Target shot at a 100yd indoor range, chrono 10ft ahead. I loaded ammo ranging in charge weight from 42 grs to 45 grains of Varget in .3 gr increments, giving me 11 sets total, three cartridges per set for a total of 33 rounds. I followed the Instructions to the OCW method ( http://optimalchargeweight.embarqspace.com/#/ocw-instructions/4529817134) and tried to be as "scientific as possible". I shot two fouler shots and proceeded with my testing allowing 2 minuted between shots. It was fairly cool (59f) so barrel heating wasn't an issue. What I found was interesting. Around 42 grs the groups were wide open and as the charge weight progressed the groups tightened up. I know the OCW method is used to help select a "forgiving" node that will allow for some vairance in your loads, location, etc and still maintain a consistent POI, but I couldnt help but notice the group size. The best groups by far came from the 45gr Varget, measured just above .25 MOA. I checked everything I know how to see if there were pressure issues with this load but couldnt find any - no hard bolt lift, no excessive head / case expansion (measured with calipers) and the primers were flat, but no flatter than the loads with the 43.8 grs. Is this a common load, or too hot??? Now that I am at this point, where should I turn next to squeeze the last bit of accuracy out of this rifle and which powder charge looks good? Here are the chrono data: ES SD AVG HI LO 42.0 16 8.718 2520 2526 2510 42.3 17 8.544 2543 2552 2535 42.6 10 5.033 2558 2563 2553 42.9 42 23.692 2576 2603 2561 43.2 23 12.288 2579 2593 2570 43.5 12 6.928 2607 2615 2603 43.8 7 3.606 2631 2635 2628 44.1 2 1.155 2654 2655 2653 44.4 53 26.627 2664 2692 2639 44.7 18 9.018 2679 2688 2670 45.0 3 1.528 2708 2710 2707 Pics of the groups are below. As you can see, 44.1 and 45 grs both had insanely low velocity variations. When I charted this, there is actually a pattern of peaks and valleys, but the peak and valleys turn steeper as the velocuty / charge weight increases. Thanks in advance! This is becomming addicting!
  12. Not sure bout what throat I have. How do I find this? Should I get the reamer specs for my barrel from Krieger? I am using a Dillion 550B and Redding Competition Micrometer dies. Lapua cases, Wolf primers, Varget, and the bullets discussed above. I will definately get some chrono info, not quite sure why that didnt come to mind at first. I imagine many people would look at those groups and be fairly satisfied, all the groups are right around MOA and over half are well within sub moa. The 175 SMK groups are under .5 MOA but I am an absolutel perfectionsit, I know this rifle is capable of more. I want a clean 1 hole group at 100 hahaha I am on a mission.
  13. I found this last night http://optimalchargeweight.embarqspace.com/# looks promising to me due to the fact that they specifically mention it being used with great success at 100 yds to develop sub moa loads at distance.
  14. ya, I have a lot to learn it seems. My question is, does the ladder test still work at 100 yards? Right now most all of my groups are sub-MOA, with some being sub half-MOA but I am looking for every last bit of accuracy. Is ther an order I should do things, eg. first determine correct powder charge, second play around with COAL, third play with neck tension, fourth, different components etc...
