Define "rounds" a little bit first -- do you mean "bang sounds" or "projectile count"?

Bang sounds can range from 5 to 10 to 20 to 30 to 40 to 60 depending on the magazine you use (and the magazine capacity laws in your local area).

For the Evil AR round projectile counts, multiply the answer you got above by 3x .....

So, using North Carolina rules, I can pack me 180 projectiles in one load up for wild pig herd thinning uses, something that makes Beto positively drool to come to get my 3x Evil Evil Evil AR.    

What stops him is simple reality --- a 12 gauge shotgun does 3 times more per bang than my evil AR does per bang.  

And even Beto isn't stupid enough to go after the shotguns, not even the Brits will go there .....


How fast did the old long single shot Kentucky rifles sling a 36 caliber ball using black powder?   1,550 fps is what modern chronographs apparently see --- which is pretty slow since I can sling 3 of them almost that fast with BLC-2 without straining things too much.

Shotguns do 1350 fps regularly with buckshot loads. so these speeds are obviously quite deadly within 50-100 yards.   80 yards is considered a common "maximum range" for shotgun buckshot as it starts to spread too far about then.   Not because it won't penetrate and kill, it just goes out of control.

The Evil   AR won't have that 80 yard maximum problem, as each pellet is spin stabilized as it would be from a Kentucky rifle.

Just a little tickler about multi-ball loadings in the 350 Legend rifle case.

I think they will separate during the trip up the case and into the forcing cone and into the barrel.

Certainly the balls will separate upon impact, making a cone shaped dispersion pattern inside the target animal.

The "3 balls still on the string" weigh within 10 grains of what the large rifle bullet weighs, and they will use the same powder charge which will barely fit under the "string of 3".

This means instead of banging a single 66 grain .224 bullet at feral pigs with a standard AR-15, you can now hit them with a string of three .355" balls flying true at greater than shotgun distances and rapidly eradicate them seed rooting nuisance making feral pigs more effectively.

Yep, the first one twists itself free of the larger mass of the remaining two upon entering the rifling, the middle one gets another twist relative to the last one when it hits the rifling, then the last one continues increasing the twist slightly while the middle one exits the barrel and stops increasing, thus reversing the direction of the twist differential between the two.

Lit burning powder gets blown in between the last two pellets when the case walls first expand to hit the chamber walls, so you got some powder pressure differential between the last two balls that will also cause them to separate going up the bore.

We know from the shotgun guys that they do not bother to separate the strings of 3 pellets as they will hit paper 50 yards away as separate pellets having just been choked once going up a smooth bore, so I think if the firing forces and a simple gentle choke are enough to separate the pellets jest dandy then I am fine in my rifle.   I have more severe forces in my gun as I am not over an ounce of shot getting slowly boosted to 1350 fps, I am a line of single pellets getting boosted up over 1550 fps fairly abruptly, dealing with a lot more force to do that in a shorter distance and a forcing cone and a rifling twist.

The shot to shot junctions will get flatted pretty good I suspect and the twist action will sever the little lead string in the middle of the flats between the pellets pretty good I suspect.

I also think this load would really confuse the heck out of my chronograph, with three little shadow blips flying past it in a row .......

Been getting some requests for a heavy subsonic load for the Legend for those who love silencers and potting pigs at night using infra-red scopes.

Got no silencer personally, I don't personally need a subsonic load for any reason ---- but such is possible using tech I have already shown to folks.

The lead locomotive in the Blue Train is a 125 grain LEE 2R 9mm pistol slug that the mold is currently available everywhere for $24-$30.  This hangs out in front of the case giving it out of the magazine and into the chamber lead in guidance that the little round ball really lacks the ability to do to a large degree.

With 3 balls it could only be a sub-sonic, cut the ball count down to 2 and it could be a fairly respectable heavy rifle loading.

Weight of lead is 335 grains for the four projectile load (as shown) and 265 grains for a two ball with the Luger style bullet in front.

These extremely heavy load weights may require slow powders like WC872 for a slow start if you were trying for supersonic, but seeing how much lead is involved the WC872 will likely have lots & lots of time to burn completely.

Or do what the shotgunners do, simply use some fast pistol powders like Blue Dot but only use a little tiny bit of them.

Upon loading the balls, you will get a chain of bulges in the case that would require insertion part way into the full length sizing die just to iron the bulges out.   This is no sin because you need to stick the finished round into the full length sizing die anyway to slow taper crimp the case mouth into the first bullet.

The lead alloy is air dropped wheel weight alloy and firing such loads will likely immediately "slug the chain of pellets up" upon firing to whatever the chamber wall and the expanded case will allow ---- the forcing cone comes next and reduces it all back down to .355" anyway.

Think revolvers and the cylinder throat slugging action and you will realize we do this sort of stuff all the time anyway in our pistols.

The untouched bullet in the front always caps the fizz anyway, so it isn't like any pressure will be lost and the entire blue train will still exit the station in an organized fashion.

MM, it is not a lube.   It is Ford Light Blue powder coating from Eastwood Corp.   Ford uses it to coat rocker arm covers and oil pans.   It is a fine blue polyester powder that you tumble the bullets in bulk (I use a small bowl tumbler) and you can do hundreds of bullets at a lick.

Then you put them on parchment paper on a cookie sheet in the oven at 250-300 degrees and fuse the powder into the slick coating you see on the slugs.   You cure it for 30 minutes total, then let it cool.

The stuff is tough, you can scratch lead with your fingernail but a fingernail will never make an impression on the powder coating.   You can beat a coated bullet with a hammer and mash it flat, and the flexible tough coating just moves right with the mushed lead.

Expanded bullets will keep the coating on the unabraded lead, it acts sorta like a thin jacket in a lot of ways.

All of the bullets you see have been sized to .3565" in a LEE push through sizer after coating and curing, none of the lead shows because the powder coat is just that tough.

Read up on it on YouTube, lots of videos out there as folks begin using it all over the place.
