Help me diagnose popping primers

Well, I dunno if 200fps is a lot of gain over say 600 rounds, but it sounds like a lot to me. I don't normally have to chrono before every match with my other rifles, but I do with this one.

Base of case to ogive is very consistent with loaded rounds. Plus or minus a couple of thou. As mentioned in the OP, I checked a couple hundred unloaded bullets for ogive to base and there was only a couple thou difference across them all.

I have no way to determine if the chamber is cut correctly, but with the exception of the 8-10 rounds that popped primers, all the fired brass looks perfect.

Not sure exactly what your asking in the last line. Are you referring to the diameter at the shoulder and base?

I don't understand


Sizing is pretty standard in all reloading unless you are a neck sizing person.

I undersize the expander then us a mandrel to get what I want and don't ever consider neck sizing again, didn't like it.

I bought these cases and never meant to reload them. Plan was to Just pull them from the bag, prime and load directly out of the bag, fire and leave on them on the range. If they fit, there would be no need to size.

As it turns out, I need to FL size to get them to work and because I’m forced to size them anyway, I see some deficiencies with the way this die sets neck tension.

More lies revealed. Oil didn’t come from Dino bones 42 miles deep

Saturn's moon Titan has abundant liquid hydrocarbons, including methane and ethane, that are similar to but not the same as oil and natural gas found on Earth. These hydrocarbons are derived from the planet's vast organic chemical inventory and form lakes and dunes on Titan's surface, containing more of these substances than all of Earth's known fossil fuel reserves.



Titan's "Hydrocarbon Oil"
  • Composition:
    On Titan, the liquid hydrocarbons are primarily methane and ethane, which are gases on Earth but remain liquid in Titan's frigid temperatures.
  • Formation:
    These compounds are produced from the breakdown of organic molecules by ultraviolet light from the Sun, creating a "giant factory of organic chemicals".
  • Abundance:
    Titan's surface contains hundreds of times more liquid hydrocarbons than Earth's oil and gas reserves.
  • Location:
    These liquid hydrocarbons collect in large lakes, seas, and rivers, with notable bodies like Ligeia Mare
Distinction from Earth's Oil
    • Origin:
      Unlike Earth's oil, which forms from the remains of ancient organisms, Titan's hydrocarbons are created abiogenically (without life) through geological and atmospheric processes.
  • Definition:
    While the terms are sometimes used interchangeably, Titan's hydrocarbons do not strictly meet the definition of "oil" or "natural gas" as understood on Earth, which implies a biological origin.
Once again proving my point, AI is retarded.

Organic compounds are chemical compounds that contain carbon (C) atoms, usually bonded to hydrogen (H), and often to other elements such as oxygen (O), nitrogen (N), sulfur (S), phosphorus (P), and halogens (like chlorine (Cl) and fluorine (F)). They are called “organic” because they were once thought to come only from living organisms. Today, we know that organic compounds can also be synthesized in laboratories. [1-4]

Budget 300 Blackout Build - Suppressor Suggestions

If you're going budget, I'd at least check out the YHM R45. Its been a heck of a do it all can. For what you're thinking about doing, no adjustable gas block shooting subs suppressed and supers unsuppressed you are going to want a high back pressure can.

I have not seen a scenario where you can run both supers and subs either suppressed or unsuppressed without the use of adjustable gas. Without adjustable gas, a standard baffle stack can will probably work the best. That way you can tune it to run subs suppressed and then supers should run fine when I you remove the suppressor.

Personally, I'd just bite the bullet and get an adjustable gas block. I run all 300 BO suppressed, whether supers or subs. With the R45, subs are pretty dang quiet. What I hear mostly is the clack of the bolt running. With supers, it's a LOT less loud.

For the price and within its barrel restrictions, the R45 is a good performer.

I'm kind of surprised at all of the recommendations for flow through suppressors. The purpose of a flow through suppressor is to make your rifle think it isn't running a suppressor at all, in terms of back pressure. That puts you back at square one trying to run both subs and supers with an unsuppressed rifle, without having to adjust the gas.

If anyone has accomplished this, I'd sure like to know how.

Of course there varying degrees of "flow through" and some may be much less flow through than others.

He is pretty sure that it was the end of the handlebars. They are bent to shit, the hand grip is torn off, and the bruise right under the cut looks like a bar print. He was pretty concussed and loopy immediately afterwards, and the crash details are fuzzy.

Why don’t we run a hose from Titan to Earth and stop harmful pumping on earth. Plus, if we pull too much out of the Earth it will shrink like a leaky balloon, and we don’t want that. All the islands will flip over and Florida will be drawn closer to Haiti, and we definitely don’t wanna get any closer to that shithole!

Help me diagnose popping primers

That base doesn't look very healthy to say the least.
1st-200 fps is a lot of gain?
2nd-Have you checked all of the ogives on these bullets after loading or even before loading
Is the chamber cut excessively large at the base?
Have you measured the body at the shoulder and base, compare new, sized and fired-although we know the fired one is off at the base!

Bye bye tail rotor.

There is another much clearer video out there which appears to show a possible pitch link failure for one of the tail rotor blades which then sets the whole sequence of events off; with intact and unburned wreckage plus multiple videos I'm confident the FAA will come up with a definitive cause. Sometimes video compression artifacts mess with things, so I'll put what appears to be a pitch link failure in the video down as a possibility and wait for the official accident report. But in the mean time we'll gets lots of speculation from expert internet accident investigators.

Pilot appeared to be solidly in the dead man's curve of the H/V diagram when things went sideways and didn't have many options, things could have ended up much worse than they did for both the people in the helicopter as well as those on the ground.
