    6.5 Grendel v .300 Blackout

    Do you have a point, or do you just want to insult everyone? The Whisper was a perfectly good niche cartridge. AAC broadened its scope, taking it into a market that was asking for options. They copied the Whisper, and added a supersonic load that people could use when it fit their needs. The...

    6.5 Grendel v .300 Blackout

    Guys, have any of you done ANY research on the round. AAC was determined it had to be subsonic, they wanted it subsonic, they developed it subsonic, they're a freaking suppressor manufacturer, they wanted an ultraquiet round. No way is the supersonic version quiet! They included a parameter that...

    6.5 Grendel v .300 Blackout

    The design purpose of the Blackout was subsonic use, with ability to use lighter projectiles at supersonic velocities. Since the design plan was subsonic, and longer barrels increase the probability of supersonic rounds, even when subsonic are desired, there aren't a lot of rifle length BO's...

    6.5 Grendel v .300 Blackout

    From your post its apparent you would be an expert on that, at least! Your language relegates you to the group of troglodytes that anti-gunnies wish to smear all 2nd Amendment proponents.

    6.5 Grendel v .300 Blackout

    No, actually, not one single appropriate, reasoned response. You and those like you love to wag, but can't discuss without accusing everyone else of "cherry picking" or "stacking the deck" etc. You all act like liberals who love to yell and shout about how the right does it wrong, but can't...

    6.5 Grendel v .300 Blackout

    Yes, except I recognized how far off topic we were and quit, something you apparently are incapable of accomplishing. So go on and have the last word! Now I remember why I never posted after joining almost 4 years ago. To much phallic wagging going on, too little actual help.

    6.5 Grendel v .300 Blackout

    Never mind, you're so far off the OP questions that its just useless. For the OP.....The Grendel will do anything supersonic the 300 BO will do, and will do it further out. The 300 BO shines as a subsonic load, particularly suppressed. That's it in a nutshell.

    6.5 Grendel v .300 Blackout

    LRRPF52 has "been there, done that", including humping the M249 and running the M240. He's competed at the highest levels of International long range competition, (think Finnsniper, if you are familiar with it). And he did compare the .260 and the Grendel, note that he points out the...

    6.5 Grendel v .300 Blackout

    If the reamer manufacturer was PT&G, it is HIGHLY unlikely that you have a SAAMI chamber. PT&G has apparently been carrying on their own campaign to change the Grendel chamber, and has been supplying a reamer that is their version of the .264 LBC chamber. They have done this to multiple...

    6.5 Grendel v .300 Blackout

    An out of square receiver is another possibility, and I should have mentioned it. That essentially creates the same situation as a bad barrel extension, with thrust on the lugs produced unequally. I would have hoped that any competent AR smith would have squared the receiver and Nukes seems...

    6.5 Grendel v .300 Blackout

    Broken bolts can only come from 3 things really: 1) Bad bolt. This included bad metallurgy, bad heat treatment, bad machining, etc. 2) Bad barrel extension or a combination of tolerance stacking between the bolt and barrel extension. 3) High pressure. Since the VAST majority of Grendels...

    6.5 Grendel v .300 Blackout

    Which makes it even more likely that you have a bolt/extension issue. But treat it how you feel most comfortable. History says that this kind of an issue is related to a bad extension.

    6.5 Grendel v .300 Blackout

    As people are rapidly finding out, many manufacturers are relying on the reamer maker to build the reamer to the SAAMI spec, and then are finding that it is otherwise. Even reputable barrel makers like Lilja have been caught in the practice by reamer makers. Your bolt failures fall FAR outside...

    6.5 Grendel v .300 Blackout

    There, fixed it for you. I forgot that people on forums have a hard time reading and comprehending anything that has more than three complex sentences in a row per paragraph! :) Just kidding, I composed it in Word and cut and pasted and the forum took out the paragraphs for some reason. As for...

    6.5 Grendel v .300 Blackout

    Having followed the Grendel almost since its inception and watched the flame wars its proponents had with 6.8 proponents, I am comfortable in asserting that the whole bolt "issue" was a combination of bolts that were not properly manufactured and hand loading. Since 2008, bolt failures have...

    6.5 Grendel v .300 Blackout

    The OP asks for opinions, unfortunately. He got lots of those, but too many not backed by any statistical information or fact. Lets look at the rounds objectively: 300AAC/300 Whisper: GREAT subsonic round, and the more aerodynamic bullets allow it to be used reliably out to ranges that...

    F T/R Competition F/Tac, or maybe F/practical

    Re: F/Tac, or maybe F/practical Vu, I understand the FTR limitation on .308/.223, but I think its a mistake in tactical. If someone wants to shoot a low recoil round like the 6.8 or the 6.5 Grendel, etc, they are forced into F Open, where there is NO chance of being competitive. Thus they...
