  1. I don’t know man. I just go to the shooting range and I start blasting away with my Ruger 556. Accurate enough for me at 200, 300 yds. I’m not really into all that twist & grains crap. The most grain bullets I ever found is 62gr. So we’re good !

  2. Personally can't speak to the RRA, but the 1/9 heavy profile barrel on the M&PS2 is the whole reason to buy it instead of other entry level rifles. The thicker profile gives the barrel more stability (than budget pencil barrels) meaning generally better accuracy, and the lower twist rate reduces wear and improves durability. These features come at no cost in stability of higher grain bullets.

    If a budget shooter is instead interested in the weight savings of a pencil barrel or 1/7 twist because of "Milspec", then other offerings are probably a better choice.

  3. As with anything put on the internet, you will have the cadre of keyboard warriors out there that apparently only know what is put out, on the internet, by someone they don't know but their opinions are for some reason reputable to them or the simple fact that some calculator says it ain't so. So many of those naysayers have never been in a situation to even try what they say ain't so. Its easy to sit behind a keyboard and spew facts about something you don't know anything about just with a little google in your pocket. In my experience facts ain't facts until you try it on for yourself. I think from a 16" barrel, less than two minutes vertical and what appears to be less than one minute horizontal is pretty telling. Imagine what could be if hand loads were used; but then load development would have to be done to find that load. Another subject not many on the internet understand.

  4. I'm a millennial, but I fought the last 2 wars. Most millennials have their heads so far up their as* (or their parent's as*es because it's cheaper) they don't know what they are talking about. This segment of the firearms community really makes topics like this very difficult. The internet streamlines non-sense to people trying to learn.

    Nothing beats experience and results YOUVE made within your shooting system. Awesome video and fantastic shooting!

  5. I have a Colt SP1 Commando with a 16" HBAR 1/9 twist and from my personal experience I have no trouble shooting 77 Grain bullets out to 500 yards. However i have noticed when shooting 55 to 62 grain I have a tighter grouping than I do shooting anything heavier than 62 grain. My Sig 556 with 16" barrel and 1/7 twist does not have this problem. I will admit this could be me as I am shooting iron sights and my eyes are not what they use to be. I wish I had a 1000 yard range locally as I would like to see what I can do at that range with my Colt or Sig as well as my Mil Surplus bolt and semi auto rifles.

  6. You are exactly right. You have to test each individual barrel to know exactly what it likes. For example I have a 9.5" voodoo 300 blackout barrel with a 9.5" twist. I have shot 1/4" groups using Hornaday 110 gr. v-max factory ammo. Doesn't make any sense but I know it does because I just had to try and find out for myself. Now I am glad I did.

  7. It's like the current don't drop your slide on an empty chamber with a 1911. It's your gun so within safe parameters use them how you want to. The twist charts are a starting point and on some of those charts the 77 is on the edge of the margin. Clearly he determined his personal firearm was capable of using that round. This is a great example of knowing the limits and capability of your weapon. The people that use charts as a cudgel are statisticians not firearms operators.

  8. Great video👍🏼👍🏼👍🏼 People will always disagree no matter how often they see the truth. They just don’t have the courage to admit they were proven wrong. Keep up the great work and and don’t let the misinformed get you down.

  9. While not the greatest groups at 1000 yards your point was well made. Chris H, I guess you feel pretty silly right about now? Amazing how some people will offer "facts" and not really know what the hell they are talking about. Most likely an "armchair expert"!

  10. I bought a 1/7, as it was cheapest option for something I'll hardly use. Longest range available to me, is 25yds, and it shot anything I tried well. Only issues I've encountered, was the ammo itself, such as rounds falling apart in the mag from crappy crimp jobs.

  11. Excellent vid & content. Bullet design and atmospheric conditions [temp, altitude] are going to be more important to whether that 1:9 barrel is going to play nice with a bullet than the grain wt. alone.

  12. Very interesting results. Include me in the camp that didn't think a 1/9 twist would stabilize a 77 grain bullet at greater distances. I am quite pleased to be proven wrong. Nice shooting and a welcome video.

  13. I have a 1:9 twist piston AR, it shoots everything I've put through it fairly well, it actually does great with 77 grain at 400 yards, which about max I'd shoot an AR anyway. so…

  14. On paper it may not be "ideal," but practically speaking 1:9 clearly works well enough. Considering the effective range of 5.56 is half the distance he was ringing steel at, 1:9 on a gas gun works just fine for its intended purpose

  15. I have this same rifle, and for whatever particular reason, mine does not seem to fire 77grains well at all. That being said, it shoots 55-69 grain bullets very very well. Overall I am very happy with it as a lightweight liberty defense rifle. It just shows that at the end of the day one must always test their rifle with their intended ammo. Like you said, you can't always believe everything you see online.
