  1. WTS CMMG .22LR Semi Auto

     

    Wonderful semi-auto .22LR built on a CMMG action with Magpul stock, pistol grip and forward grip. Magpul MBUS pop-up sights. 16” barrel. 

     

    Fore-end 12” rail is Daniel Defence AR15 Omega Quad Rail

     

    Hiperfire HiperTouch Competition Trigger. 

     

    Magpul BAD bolt hold open lever. 

     

    3 x S&W 15-22 magazines runs flawlessly. 

     

    I have a few spare springs, firing pins and spare parts kit that I will include. Rifle is in excellent condition as you can see. 

     

    £750 to your RFD in a hard plastic case.

  2. Stop talking nonsense - new shooters know they are welcome and the actual winner of the match was in the U.K. last weekend training new shooters with someone you’ve just had the audacity of accusing doesn’t support new shooters and has done more to bring in new shooters than anyone.

    You posted something incorrect about the match and a link to a sponsor that didn’t sponsor the match. Support the match, support the cause and support the sponsors who supported both !

    To be honest don't know, ive not used it as yet, my club hasn't got a range booked till the middle of June!

    it looks a bit strange i guess, but it can be moved fore and aft so with a thumb up grip it feels good.

    Its not overly expensive and easily changed so i thought worth having!

      

    Could you show us a pic inside the magwell ? I’m curious how the action interfaces with the chassis. Thx

    I've got a couple of pounds of Alliant Re16, yet to try it - but on paper it looks a good option in this bracket. This is one of the new Swedish (Bofors) made Alliant grades with the company's 'TZ' temperature technology and is claimed to be as good as H4350, possibly better in this respect.

    As to applications and burning speed, it's very close to H4350 but can usually produce higher MVs if loaded to maximum levels.

    See:

    http://bulletin.accurateshooter.com/?s=Alliant+Reloder+16&submit=Search

     

    Norma (all of whose powders are made by Bofors) appears with a couple of additions such as URP to be offering an unchanged range from say 20 years ago without any updates, and this seems rather unlikely given the way all propellant manufacturers have ugraded their products in recent years. So, it may be that today's Norma N204 and Alliant Re16 are one and the same thing. (I have some N204 on the way too and will be able to compare their grain structure, density, and performance.) Right now, the reintroduced Norma grades are considerably cheaper in the UK than Alliant powders, worth considering by British forum members. (Re15 and Norma 203-B are one and the same thing for instance.)

    Very interesting. Is RE16 a double-based powder ? Temp sensitivity looks excellent but just wondering if it is double based / how they get such good velocity ? Thx

    So i got this from swiss reload 

    Temperature coefficient          m/s pro K

    RS36 7.62mm x 39 0.60
    RS40 .223 Rem 0.45
    RS50 .308 Win 0.70
    RS52 .308 Win 0.55
    RS60 8 x 68 S 0.25
    RS62 .270 Win 0.90
    RS70 .300 Win Mag 0.45
    RS76 7mm Rem Mag 0.20
    RS80 .338 Lapua Mag 0.20

     

    Looks like rs62 is the most sensitive per c? Any sugesstion to try another EU powder for 6.5 creedmoor ? N550 ? 

     

    Thx. N550 is 1.00 so not really a great option for temp sensitivity

    I have had mine for a few weeks now, hooked up to my Garmin 701.
    They work great, glass good for the money and have pinged horses out to 1200m, large barn at 2167m in perfect conditions in the morning.
    Just remember unless you bluetooth them to a Kestrel or Garmin, it will only give a ballistic solution to 800 yds. 

    I’m getting out to almost 5000 yards ! Crazy. 

  7. If it is basic and maths why do different apps account for it differently ?

    I love Brian’s work and follow him religiously but he’s saying we need a custom curve for bullet, he’s saying spin drift is more than many other ballisticians and he’s saying coriolis matters....and he’s selling software to measure and compensate for these. The truth is the best shooters in the word don’t use it and we all know in our sport everyone chases performance the the enth degree. If it made a difference at the enth degree shooters would embrace it religiously. You need to ask yourself why they don’t. 

    PS I don’t they think are flat earth examples at all. They are simplistic for sure but they make sense don’t they ? The earths atmosphere moves with the earth. Outside of the atmosphere coriolis does exist, is extremely material but for the few seconds of bullet flight it doesn’t matter. 

    Its super interesting but the reality is nobody has ever conclusively proved it matters for our sport. That in itself is interesting. There is argument and debate but if it is as simple, calculatable and basic physics as you say then why is there so much debate and discussion ? Is it because shooters have and haven’t seen the difference after firing billions or rounds downrange ?

  8. Jacob gives a very simple example of Felix Baumgartner, that guy who jumped from space. He took several hours to ascend to the edge of the atmosphere at 128k ft and then jump back to Earth in free fall for almost 5 minutes. Where did he land...pretty much exactly where he took off from. How is that possible if the earth is rotating around it’s axis at 1,000 MPH. The Coriolis Effect says he should have landed in the Pacific Ocean but he didn’t. In the two hours he took to go up the earth moved 2,000 miles (actually less because he wasn’t on the equator). Now think about a bullet. It doesn’t stay airborne for more than a few seconds and it doesn’t go that high either. The earth’s atmosphere moves with the rotation of the earth.

    If coriolis mattered and I wanted to travel from London you Cardiff I would hire a helicopter and hover. The 150 miles would close in 10 minutes or so and all I would have to do is hover 25 feet above the ground.

    If the earth moves at 1,000 mph how can an airplane travelling at 500 mph from say Madrid to Tel Aviv ever arrive ? It’s because the atmosphere is travelling at the same speed as the earth. If it wasn’t, we would have constant cyclones.

    Says who?  I can't find any supporting evidence for your view, could you point me please as I'm quite interested?

    Says most of the leading precision rifle instructors and top competitors. It’s actually common knowledge that most turn off this feature. Attend any high quality course and this topic comes up time and again.

    If you are genuinely interested have a listen to this podcast by Jacob Bynum who is widely regarded as one of the most respected instructors in the world. He gives some amusing examples why coriolis doesn’t matter in shooting.
