6ar turbo 40 fire forming issue

I’m having a problem with fire forming cases in my 6ar turbo 40. I fireformed 50 hornady cases with zero issues using the false shoulder method to keep the base against the bolt face. I then loaded 100 virgin lapua cases using the same method. Shot 15 and had split shoulders on half of them. I have several wild cats and a few of those are ackley or other forms of improved cases and have never had anything close to a 50% failure. Any ideas on what might be causing this?

I have the gas block shut off so it is acting as a bolt action during fire forming. I will say the cases are difficult to extract but no signs of overpressure.

Upper Receiver to Barrel Nut Thread Tightness - Does it matter at all?

Sometimes you get a barrel nut that has a pretty tight fit with the upper receiver threads (no play, you need to use a bit of force to thread the barrel nut all the way) and other times you get a barrel nut that threads on super easy and wiggles around on the receiver threads until it tightens up against the barrel extension lip.

Does the tightness of the thread fit between the upper receiver and barrel nut matter at all if you are trying to squeeze the most accuracy out of your AR?

I’m curious if barrel nut with loose threads (but is properly torqued) is more likely to cause rail deflection or barrel harmonics issues?

Does the presence of Aeroshell grease on the threads make this whole topic irrelevant?

I don’t think I’ve ever seen this topic discussed.

Georgetown Students Offered Post-Election Legos and Cocoa in ‘Self-Care Suite’


Legoland Windsor Resort unveils its tributes to British Athletes including Max Whitlock, K

John Nolte5 Nov 2024257



Students at Georgetown University’s McCourt School of Public Policy will have access to Legos, cocoa, and coloring books in a post-Election Day “Self-Care Suite.”
“In an email to McCourt students,” reports the Free Press, “Jaclyn Clevenger, the school’s director of student engagement, introduced the school’s post-election ‘Self-Care Suite.’”
“In recognition of these stressful times,” she adds, “all McCourt community members are welcome to gather. . . in the 3rd floor Commons to take a much-needed break, joining us for mindfulness activities and snacks throughout the day.”
Here’s the list of activities, and the Free Press assures us this is not made up:
  • 10:00 a.m.-11:00 a.m.: Tea, Cocoa, and Self-Care
  • 11:00 a.m.-12:00 p.m.: Legos Station
  • 12:00 p.m.-1:00 p.m.: Healthy Treats and Healthy Habits
  • 1:00 p.m.-2:00 p.m.: Coloring and Mindfulness Exercises
  • 2:00 p.m.-3:00 p.m.: Milk and Cookies
  • 4:00 p.m.-5:00 p.m.: Legos and Coloring
  • 5:00 p.m.-6:00 p.m.: Snacks and Self-Guided Meditation
As a proud member of Generation X, this blows my mind. If someone tried to treat my generation like babies in middle school we would have laughed them off the planet. This is college. This is not just college, this is Georgetown. What have we done to raise a generation that would not only stand for this, but welcome, demand, and participate in it?
I can see getting drunk. I can see lifting weights, going out for a run, or eating an entire birthday cake in front of a Married with Children marathon. We all process our disappointments in our own way. But this is beyond coddling. It’s actually sinister.
Georgetown understands that keeping young people spoiled, coddled, entitled, and psychologically incapable of dealing with anything that does not go their way ensures one thing: the forever-infantilized will forever vote Democrat.
Sure, you ruin the lives of these kids… yes, you turn them into neurotic babies with thin skins, no sense of humor, and no way to cope with setbacks, which ensures a lifetime of misery… But they will vote the way you want, and that’s all that matters.
One of the key secrets to a happy life is the ability to laugh at yourself, to shrug it off, and move on. If you can’t do that, you will live a life of misery swathed in unearned smugness. What a terrible thing that must be.

What are you using?

So I competed in the MLSC this year for the first time. I thoroughly enjoyed it and want to compete in more matches like this or NRL Hunter style matches. My question to yall is what calibers are you shooting when competing in these. I am trying to finalize a build plan for a new rifle. I have been thinking about 6.5 PRC, 7 PRC or even 280 A.I.

Thanks in advance

Description

The HALO-LR

The HALO-LR by N-Vision Optics is one of the most advanced thermal scopes available on the market. The HALO-LR features a compact design that is lightweight and durable with a shock resistant body and IP67 waterproof rating. It provides a wide field of view and is well suited for nighttime medium to long range shooting.



Observe and Engage in Complete Darkness

Unlike night-vision that requires a small degree of light, the HALO-LR is completely thermal based, allowing the user to observe targets in complete darkness. It utilizes 4 polarity options: Black Hot, White Hot, White Edge Detect, and Black Edge Detect. Black Hot displays heat signatures as a black silhouette cast over a predominantly white backdrop, while White Hot shows a white silhouette cast over a predominantly black backdrop. Black and White Edge Detect casts either a black or white outline along the edges of heat signatures for a more defined image.



High-Tech Shooting

The core of the HALO-LR’s system is its 640x480, 12 micron sensor with a rapid 60Hz refresh rate. This highly advanced system is supported by a 1x/2x/4x/8x digital zoom function with a base magnification of 3.5x. The HALO-LR also come equipped with a Region of Interest Optimization function that enhances the clarity of your point of aim. This function is preset to your point of interest’s size of either ¼ or ½ of your screen. In addition, the HALO-LR is photo and video compatible, with photos being captured by enabling the photo function and quickly pressing and releasing the power button, with video being achieved via external DVR and analog video-out cable.



Features of the HALO-LR Thermal Scope:

  • Germanium coated optics
  • Digital Zoom: 1x/2x/4x/8x
  • White Hot, Black Hot, Black Edge Detection, and White Edge Detection polarity modes

I voted today.

Got there pretty early, line wasn't too long. A guy behind me had on a Trump t shirt. I told him 'Lets try this again. Maybe they won't steal this one.' I also told him I doubt they would let him in wearing that shirt. He seemed ready with his answer and said it's protected under free speech. Yeah I know but they still will probably make you change it or turn it inside out.

Just then this liberal looking fucker with a Sierra Club cap, they have that look, came up and told him he couldn't wear that shirt. Shirt wearer recited the same line he told me, it's protected under free speech and he wasn't going to take it off. The Liberal looking hall monitor said well then he'd just call 911 and pulled his phone up. Lady behind him told him 'just go turn it inside out and vote.' The guy went in the bathroom and turned his shirt inside out and came back.

I asked the Liberal looking turd, 'So you think that t shirt was going to change Kamala voter's minds to vote for Trump at the last minute?'

Lot of old boomers wearing maga hats.

Rifle Scopes S&B Exos. 👎

Question here. It will be at the end but to give some info.

First S&B purchase. Well first time really spending any time behind one.
I’ve been waiting and waiting for a S&B that I could afford. And really wanted the EXOS moa.
Finally picked one up.

I know I’ll catch shit for this, but I always compare my NX8 4-32’s to everything. Some want to trash them, but the glass is actually excellent for what they’ve been able to accomplish with the size and amount of lenses.
Their low light is exceptional and the resolution is as well.
The complaints about tight eye box…if people would just take the rear ocular Tenebrex cover off, it completely changes the view. Night and day. It does not have a tight eye box. At all.

Anyhow, this Exos I have. Spent 3 days with it. Like full days.

The eye box is the worst on any optic I’ve ever experienced. Above 12x is super tuff to get behind.
At 21x the resolution is meh. Anything under say 1500 yards seems decent. But looking long range every other high end optic I have is better.
And the chromatic aberration is terrible.
Also, the FOV is considerably less than most all other scopes I have. Including my Kahles 525i’s.
Also see no noticeable increase in dawn/dusk light transmission over anything else I have.
And I’m very much aware on how to set focus and parallax to begin with to eliminate the above mentioned.

The build quality, turrets, illumination, etc is exceptional though. Very nice!

So brings me to my questions.
I really want to like/own an S&B. Maybe a PM2 or Polar.

But, from those who have owned or own any S&B’s, is this typical across the board? The terrible CA, the small field of view, the super tight eye box? The not the greatest resolution at extreme distance?
I can return the scope for a different model, but not sure it will get me anywhere.

I have Kahles 318/525, ATACR’s, Mark 5’s, Minox ZP5, Zeiss V8, Swaro Z6, Leica Magnus, March FX, Leica PRS etc.
All have less of the negatives than everything I mentioned above.

I can’t imagine I have the one that’s slipped by S&B’s quality check.
I guess what I’m getting at is I’m extremely underwhelmed at what was supposed to be a $4k optic.
