Powder Coating Buckshot

[Rattlesnake Charlie]

Nickle Plated Buckshot

Someone mentioned this as "hardening" the pellets. It is only a coating. I pattered different 00 buckshot loads a decade ago. The plated but not buffered S&B shells were not exciting. At the time the best I found was the reduced recoil police Remington eight pellet load, which was buffered and not very hard lead pellets. I believe that reducing velocity reduces pellet deformation and thus improves patterning. I'm talking about no more than 20 yards now which was my specified distance as I was looking at personal protection. I never tried them at LONG distances.

My go to factory load for defense is the Remington 8 pellet load, followed by the Federal 8 pellet load.

I cast my own #4 buck and load a 2 and 3/4 hull with 15 gr. Of titewad with a cb 0178-12 wad and 17 #4 pellets for home protection. Very good pattern. I shoot these out of a remington tac 14

Once you bake the powder coat on the lead will lose all the chilled hardness you may have added. That is to say if you heated your Buckshot to about 440°F and dropped them into water they will be harder than as-cast. If you then tumble them the chilled hardness disappears as lead work - softens unlike steel that work - hardens. Same thing with reheating the shot. My cast rifle/ pistol bullets are sized then chilled (my alloy works best at 450°F as 460°F some will sag or remelt altogether) then lubed in a die that is at least 0.001" larger to not work the bullet lands.
The problem with uncoated buckshot is the setback at firing literally solders the pellets together as well as deforms them. Graphite, nickle, copper or powder coating keeps them from sticking together. The shot column will not break apart uniformly. Because I double chill my buckshot after tumbling for 10 hours the steam blows any graphite off the shot. I use Hornaday's spray case resizing lube on a flat cookie sheet to coat the buckshot as it is inert to powder and primers and prevents the buckshot from sticking together on firing. And my alloy is 11+% SB so it is about 18-20 Bn after chilling. Anything to keep it round...

The other day I test fired 2 different #4 Buckshot loads
Both were the same load
But one load used powder coated and the other non powder coated #4 buckshot from my LEE mold
All of the #4 Buckshot was cast from a alloy that is 3/4 WW and 1/4 Linotype

I use a Steel Shot Wad the CSD114 wad
These come un slit
So I added 3 slits 1/2 way down the wad for this test
20 gau card wads
I used Steel Powder Lot #2 , 100 PSI wad pressure
CCI 209 M primer
52 #4 buckshot pellets
BPI Original Design Buffer
Federal Steel Shot 3 1/2" hulls
Remington Versa Max with a 28" barrel
A 30mm UltraDot Red Dot
A extended range buckshot choke tube , Carlson’s Coyote Choke

Not sure of the velocity

The test shots were shot at 60 yards

The BIG limiting factor is ME
As recoil is STOUT
So I only shot 3 of each load

I used a 8 foot x 12 foot chunk a 3/8 plate steel painted with cheap white house paint
With a 4" black dot painted on with spray paint and a cardboard stencil

After each shot a measured the spread and marked down pellet hits and locations in a note book
Then the steel was repainted

The powder coated pellets max spread was on average 3" smaller at 60 yards
All 52 of the #4 Buck Shot hit the steel every shot
Average spread for the Powder Coated pellets loads was 46"
Average spread for the Non Powder Coated pellets loads was 49"
Centers of both loads were about 10" below Point Of Aim
So I will raise the sight about 8" when I do more tests

With these results I do not plan on powder coating more #4 Buckshot for coyote hunting

I talked to a guy on his powder coating buckshot loads
He told me he did his testing with 9 pellet loads of OO Buckshot for deer hunting
But the buckshot was not contained in a wad like my loads

Someone previously in this thread mentioned that you loose any hardening from quenching or age hardening when you powder coat.

My question now is "Can you quench right after taking out of oven for powder coating?"

Too cold here right now to be in the workshop casting or anything else.

[Plate plinker]

If the buckshot is in a wad there is not much point to PCing the shot. No brainer i would have thought but still interesting that it may have made a small difference.

[sukivel]

That’s good and thorough research Johnch!

Milky Duck: Are you allowed to own Pump or Semi Auto Shotguns in AUS ?

IF your Shotgun has a Fully Rifled Barrel is it a classed as a Shotgun or a Rifle?

I've heard too many conflicting answers to these questions. What is the real scoop?

With respect to the Thread Topic,,,

If your shot is in a Shot Cup, Powder Coating is pointless. If there is no Shot Cup, it might help a little with Shot Deformation going thru the Choke. (lubricity)

How hot is the oven? You need the shot to be around 400°F for any effect. Buy a cheap HF rock tumbler and put a teaspoon of graphite in with the shot and run it 10 hours. Round shot graphite coated in one pass. Only if you want super hard shot do you need any more than that. 5% Sb gets you to about 10Bn hardness as cast and that is twice as hard as pure lead.
Just my 2 cents....

I'm kind of surprised nobody mentioned tumble lubing to achieve what the OP was looking for. I tumble lubed some 30 cal round balls to shoot in my Nagant pistol, and they seemed to work just fine.

I hitek coated 00 Buckshot...

I hitek coated 00 Buckshot...

Did it improve patterning any?

[Ausglock]

Not really.
But they look cool with a clear plastic overcard...lol

[W.R.Buchanan]

AUS Glock: What kinds of guns are you allowed to have in AUS? Pump Shotguns? Semi Auto Rifles or Shotguns? Pistols?

Is a Shotgun with a Fully rifled barrel classed as Rifle or Shotgun?
