.45 Raptor Duplex.

[SigSauerM7]

Is it possible to have a 150gr SCHP and Tungsten Matrix No. 4 shot underneath and be accurate in a 7.62 NATO casing blown out. (.45 Raptor).

I was watching these guys at Academi with these 6 or 7 +1 mag fed shotguns...

I got thinking that 20 rounds of 300gr (SCHP and BB shot or No.4 @ 2300 fps would be WAY better then some bullshit 12ga.

Even if it's for breaching....would a 300-400gr Copper matrix Frang slug in .45 Raptor be better?

No.4 Tungsten matrix shot penetrates as good as low recoil 00 buck....but you get WAY more shots. 15 inches in gel +.

0.5 oz of Tungsten Shot @ 2300fps would destroy 1100 fps 00 Buck. Right?

This load could go through like 2 F-150s....

AR10 with Shotgun Esque rounds seems like a great idea and I have not seen shit online about it.

Probably not even close to your expectations.
I've loaded shot shells in revolvers & levers guns single load in levers, plus multi ball loads.
It's mostly disappointing, the faster the twist the wider the pattern.
Mostly good for small game at 10 yds or less. Small bird shot 9 & 8 is used to give a better pattern. The faster ya go the worse the pattern. Plus a huge leading problem with lead at higher than shotgun speed.

Tungsten shot is heavy and fairly hard designed for smooth bore shotguns.
I wouldn't shoot it down a rifled barrel at high speed, and not expect damage.

Speer shot capsules are designed for low pressure (and only hold about 170 grs of small shot), as are most shotgun components.
I loaded 9mm with 7 1/2 shot at 6 ft it penetrated 1/2" plywood, but already had a large pattern, probably good for snakes at 5 or 6 ft, but thats getting pretty close.
Nothing special about them, but might be helpful for pest control.

Fair.

I have been enamored with all things Tungsten and Tungsten Matrix lately.

Tungsten BBs or No. 4 at 60k PSi got me thinking.

Money aside....Tungsten shot is AMAZING.

Puts the Benelli M4 into savage mode.

53 BBs that penetrate DEEPER then low Recoil 00 Buck in a 2-3/4inch shell.

That's fucking game changing performance for certain teams or tasks.

Those speer shot capsules...

Any way they could be higher pressure?

Like a Copper Flite control wad?

Even a large 8.6 BLK style bullet with pre fragmented disc's at the base would be good.

This idea has not been explored much but I have visions of F150s with 500 exit holes on it from 1 magazine. Lol.

 

[SigSauerM7]

This would be good but with a crimped bullet on top. Solid Tungsten would be good too.

I have tried all maner of low pressure recommended shot shells in pistols and rifles. Melted out lead 147 gr fmi to replace with small shot to increase the effectiveness of 9mm.
But the high pressure loads of 60,000 psi were never tried.
Problem with shot it takes up a lot of case volume, leaving little powder room.
BB especially.
Disclaimer
I do not own a 45 Raptor, and am not really interested in your endeavor as it is fought with problems.
But out of curiosity I did make a 45 Raptor with #4 lead shot topped with a 185 gr hollow base (to get more shot in) bullet.
Here is what I did make a 45 raptor out of 308, cut to 1.8" anneal, straight out neck with expanding mandrels.
Load with 39 gr H110
Seat a 45 caliber gas check, with 40 lbs of pressure over the powder.
Add 20 pcs # 4 LEAD shot 63 grains by weight.
Add 185 gr bullets seat in place... used 454 carbide sizing die which puts a lot of neck tension on the bullet to hold everything in place. 2.170" COAL
It's about 1900 fps in a 16" barrel.
The shot is riding on the rifling bore, spinning wildly with the bullet, it will spread out fast especially at 1900 fps for thin patterns, if any strike the target at 10 yds.
What happens pushing those lead pellets up against the bullet at much higher pressures than designed.
Would the heavy tungsten shot ding the sharp edges of your riflrng the first time out.
I'd only do this project with a scrap barrel, start with normal shotgun pressure, bore scope the barrel, if heavy shot tears up the rifling at 1100 fps... no use for further testing. If not proceed with caution, working up slowly, and bore scoping each time.
If you do not have a lot of experience and common sense I would abandon this idea and just use a shotgun.
But if you must here is one way to proceed.

.410 shorgun, for comparison, you can see you have little capacity even compared to a .410.
The powder added takes up 70% of the case, to get to 1900 fps in a 16" barrel.
Added Hornady 45 cal gascheck with pressure.
Then added 20 pellets of #4 Lead, enought shot for a compressed load when bullet is seated...notice the hollow base bullet.
Here is the finished product 45 Raptor shot bullet combination.
I could try it with lead shot and 1100 fps area cause I have loaded this type of ammo in the past.
But Not with tungsten And Not at 1900 plus fps.
If I was gonna do it, I'd try it with lead shot first.
So I caution against doing it.
But I wasted my time showing how it might be accomplished.
But this is better than being in the dark completely, If you insist that your gonna skate on thin ice.

Just got bullets for "my" project, 11 boxes of Barnes .510" bullets.
Yeah, just to see how fast I can push them, then drop back for accuracy if needed.

 

[SigSauerM7]

Wow. You move quickly.

That looks impressive.

That load would put a fast hurting on anything you would want to hit inside 100 or 200.

Anything inside 25-50 is finished quickly and with less effort then regular centerfire.

I think cylindrical and stackable prefragmented disc's would be good.

No. 4 TSS Tungsten penetrates deep but you get way more capacity due to density.

I bet with using 20 No.4 Tungsten and saving some space for extra H110....that speed could get to 2100+.

What are you doing with the .510?

Giant Subs?

 

[45-90]

Being an old retired machinist, I have to move quickly on projects, cause I might not be here tomorrow
I do a lot of outrageous stuff as some of my posts show.
Pushing the envelope in every direction.
I understand what if?
But I also want people to be careful as the pursuing these projects, and why I actually offer a viable solution if one were to go slow, and work through any problems.
I don't have a spare 45 cal barrel that I want to test in, and no tungsten shot.
So for now, that's just information that could help with a possible solution...or you could be disappointed in its outcome.
That's up to you.

My current project
I'm working with the 510 Whisper. Subs and supers. It really a fun caliber, just finished up making 700 cases for it.
It shoots 620 gr subs that explode on contact driving a hardened penetrator on through, made for 50BMG. Also 650 gr fmj and 750 gr Amax. 1002 gr lathe turned bullets are available with subsonic loads 1100 fps that put 2000 ft/lb of energy on target at 1000 yds.
Here is AR 500 plate at 100 yds with velocity about 1200 fps it starts to penetrate the Armor plate at only 1400 to 1450 it gets with the program and really beats up my new armor 500 plate.
These silver points are 750 gr Amax for LR.
And 700 newly machined 510 Whisper cases and 500 bullets.
The new bullets that just arrived are for high velocity testing hoping for over 5500 of energy.
So that's my newest project.

Hah. Those fatties look awesome!

Good for everything.

Are the 620 gr HE-I?

They are military APIT or armor piercing, incendiary, tracers, they explode on impact even at 800 fps muzzle velocity, a blast for plinking in the gravel pit.
This thin metal pipe holding a target was split wide open when hit by a subsonic APIT, as the tip exploded on impact.
Good for elephant hunting?
