Sweet! I know the area.

 

Last spring I had a few machines out in Antler and Mohall area that I was overseeing. 

 

EDIT: In fact one of the other guy's has a machine or two just outside of Donnybrook right now.

Maybe a professor here? (In link below) I remember seeing a flyer for a gunsmithing school in Pennsylvania USA but I'm not sure if this was it.

Not able to go there, that's way too far. Plus I don't see an email which would be helpful.

 

I'm sure someone here knows the math needed to do some calculations. Here's some parameters that may be of help.

 

This is a concept projectile that I made and mocked up in Blender.

  • 10.4x99mm
  • Parent case is a .50 BMG (12.7x99mm NATO)
  • Case has been necked down to accept the 10.4mm projectile, and shoulder moved closer to the base to maintain 15º shoulder angle
  • Bullet is longer than the .50 BMG.
  • Loaded round is as long as the .50 BMG.

Now let's try and make some estimated calculations as simple as possible (picture 2 for reference).

  • Cases are loaded to their appropriate maximums (see cross-section for an idea)
  • Bullets are seated to meet the case shoulder.
  • Bullet is a monolithic copper bullet weighting 570gr (a 720gr monolithic copper .50 BMG bullet was used for reference. See picture 2 for volume loss. If you want to correct me, feel free to do so.)
  • Barrel length is 29 inches.
  • Shooting platforms are two McMillan Tac-50's, with one of them outfitted with a custom .41-caliber barrel and same muzzle brake with the difference being the bore being smaller for the .41-caliber projectile, while the other is standard .50 BMG)
  • Let's set up the location at the Phoenix Rod & Gun Club, Phoenix, AZ, with a 84ºF ambient temperature, desert weather with clear skies, 710m above sea level, and atmospheric pressure set at 29.76 inches of Mercury.
  • Targets are set up at 500 yards for point of reference.

All I need primarily is the velocity of this projectile. Ballistics can really only be tested by actually making and shooting these in real life to see how they can behave, but we can discuss some theories on their characteristics, which is okay as long as it's in the realm of reality.

 

Here's some pictures for reference. Right is the .50 BMG. Left is the projectile I made using Blender.

@JurunceNK I meant you could email. I forgot to type that. I don’t know where you live but there may be gunsmithing or engineering schools or universities nearby. If the teachers are passionate enough, they may actually get back to you. Some are too busy to even reply. 

I’m not mathematically acquainted with these concepts but if you don’t email I hope someone here gets back to you.

What exactly are you looking to understand? speed? Bullet stability? pressure? case volume?

 

I can fire up QuickLOAD tonight and see about creating a custom cartridge. see what it spits out for MV of varying powders. might need more info from you to get an accurate calculation.

 

I will need details on the bullet profile. base diameter, boat-tail length to body, OAL, tip to Ogive. If this is a bullet already in production, the model number would be extremely helpful.

For the record, i predict this to be a terribly inefficient cartridge design.

It's similar to how the MP7 has an oversize case to bullet but the size difference makes a difference as it's anti personnel and armor penetrating in a small package.
There are some cartridges designed like this for long range shooting though.

I cannot think of the rifles nor ammo but here are some images that look like what I'm thinking of.

Long Range Calibers and Cartridges

These cartridges are highly specialized though. As is the .50 BMG as an anti-material rifle for disabling vehicles & causing war crimes.

I broke down and bought myself an X95!

I've always found bullpups (pardon my French for a moment) fucking sexy as all hell, but I'd had a hard time justifying the high price of most of them.

Well, I'd been saving my money for a while and of the things I'd been eyeing this was finally at the top of the list.

 

I took my Vortex Strikerfire II red dot off my AR and put it on the X95 and bought an inexpensive Bushnell TRS red dot to replace it.

While that means I'll have to go to the range and re zero both of my rifles, it also means I get to go to the range and re zero my rifles :D

 

One thing that really surprised me is the perceived weight of the X95.

Just picking my AR and X95 the they feel pretty close with the X95 feeling slightly lighter, but when I shoulder the X95 it feels significantly lighter than my AR (M&P 15 Sport II).

I'd heard that some people like the weight distribution bullpups offer (rear bias) vs traditional rifle configurations (typically front bias), and while I'll hold final judgement till after a trip to the range, just shouldering and moving with the rifles at home I really like how the bullpup feels.

I've always found bullpups an interesting form factor.

 

I can see how they would move around a lot better than ARs or other traditional rifles, since there's less gun in front of you to maneuver. I could see them being really good for home defense if the homeowner doesn't want a shotgun.

CQC is pretty much what bullpups were developed for. You get a full length barrel in a short package with a center of gravity closer to the shoulder. The tradeoff is worse recoil handling, which makes longer range shooting more difficult.

Personally, I prefer rifles for home defense in all cases. They are extremely accurate even under duress, and can be had in calibers small enough to make collateral damage minimal, which is my primary concern. Additionally, they are more easily used for property defense (dispatching an attacker before they enter your home, which may or may not legal depending on your state) than other, shorter range, options like shotguns and handguns.

My go to home invasion mitigation tool is my big ass handgun with big ass bullets that put big ass holes in big ass dudes.

 

Predators get the .223 SBR. Which reminds me, i have to buy a new 1-4x optic for it.

I would imagine legality of this can be tricky until they enter the house.

 

Outside the house, it would be hard to tell if they're an attacker/invader or not.

On the topic of self defense, it’s apparently a law in china that if a police officer had to shoot someone, he’s obligated to fire at least 1 warning shot. 

Which has resulted in innocent bystanders dying so now many carry a blank at the top of their magazine. 

Anyone have any thoughts on firing at least 1 warning shot? 

 

In home invasion, I call it a compromised position.

Generally speaking you could call a "warning shot" reckless discharge of a firearm, or at least the police might call it that. There was a case a while back where a man tried abducting a young woman who was walking with her mother, the mother fired a warning shot and scared the man off. The police charged her with "reckless discharge of a firearm". A verbal warning should suffice. Most criminals will flee at the sight of a gun because usually their goal is not worth enough to them to risk their life over.

 

Warning shots are generally a bad idea because in your typical house, a single shot from a 9mm could easily pass through a wall or two, and you don't know who/what is on the other side.


Computer's don't make errors. What they do, they do on purpose. By now your name and particulars have been fed into every laptop, desktop, mainframe and supermarket scanner that collectively make up the global information conspiracy, otherwise known as The Beast.

 

You just be careful. Computers have already beaten the Communists at chess. Next thing you know, they'll be beating humans.

The only warning that needs to be made is "Stop! I have a gun!"

I would think pointing it at the attacker would be more effective.

you stand a far better case against "ambush with intent" by announcing its presence. However B&E is usually enough to consider one's self to be assaulted with intent to inflict great bodily injury or death. The fact that you gave the intruder a chance to get right in their head goes a long way.
