1&3/8oz (600+gr) 20ga load data?

[cpileri]

Anyone know of any ultra-heavy, 600gr / 1&3/8oz 20ga data? any shell length.

I am thinking about Ajay's 20ga Super Nitro Express idea, and found these heavy .55 cal 600gr bullets that will fit nicely in CSD wads!

Not cheap, but sometimes a great idea costs money.

I am on the trail...seems to lead to the guys who are using that uber dense TSS (tungsten) shot. They load 1.5oz in 20ga! and 2.5oz in 12ga!
I just want the powder charge.
Will keep all posted.

If your gun has a fast twist it might be possible to stabilize that big of a bullet. My h&r ultra slug will not stabilize the 350 grain Lyman sabot very well due to the 1-35 twist

[jason f]

Forgot to mention that it does stabilize a 450 gr. full bore slug quite well with 33 grains blue dot.

[cpileri]

Actually, mine is a smoothebore, so will have a non-discarding wad-slug as the projectile. its just an experiment.
What i really need is the powder charge these guys are using for 1.5oz 20ga loads.
I believe they use Longshot, but no idea on charge...yet.

Hello Elite Brother Cpileri,

Take your pick, which ever you like, I would drop the charge to 19.5, 20, 20.5 & 21 gr and watch for pressure signs from there on for 600 gr slug.

You can't say we did not give you choices:

Thanks, Ajay! Those are close.
I need to post a bunch more on shotgunworld to be able to PM hawglips and get the data- might have to buy it from him but that's OK.
I suppose i could also just dump the shot out of these:

and move on from there.


heaviest 20ga load in Hevishot manual = 1&1/4oz, Steel powder @23grns., in CSD20 wad

[hubel458]

Those are 550 magnum jacketed bullets we helped develope.
I made the first cases years ago from 460 Wea brass
I was in on the first order of 550 cal bullets that Hawk made.
I put pic in 12ga FH thread last year,
shown in CSD wadcup right front in picture

As for loads in 3" plastic, about 45 gr 4759 to start.
Be more accurate in smoothbore with minie slugs
and even better to glue the minies in so it would
work like the brenekkes ..Ed

really?!?! That's awesome. Small world! As an aside, that 550 magnum cartridge looks really cool. If it didnt need a "sporting' exception to rule (being over 50-cal), i would be looking into it harder. But back to shotguns...

So you think the 550 jacketed are too long to be accurate, and to just stick w minie balls?

[hubel458]

Without rifled barrel those would be hard to stabilize.

If you need a real big bore sometime my 585 HE has
better supply of cases( 3 barrels of them)
and more barrels full coming, and bullets and a
sporting exemption. Bullets 550,650,750,900gr jacketed
and half dozem 585-587" Minie bullets that work...Ed

[cpileri]

Thanks,Ed.
Will the 45gr of 4759 load be within SAAMI, or upwards into FH territory?
I am using a factory, non-NEF USH, regular-ol' 20ga; so need to be within spec.
C-

[hubel458]

If you use a 450 gr Minie or lighter I would be within SAami.
How heavy is the muzzle of the 20ga. What is the OD.
If it is .820" and modern gun it would hold 55gr ofl the 4759.ED

[cpileri]

The two barrels i have to use are muzzle 0.745 and 0.768, neither were ever intended to be heavy slug guns.
So i'll push to their design limits but i cant be really heay like i want to- at least to try.
Thx for the data for the 440's, and SAAMI level limits for the 600gr loads in 20ga?
I am over on shotgun world scrounging for data for loads up to 1.375 and even 1.625 in the 20ga! Those should at least get me started.

[hubel458]

When you get 600gr in 20ga with too light of a barrel you'd have to go so
much less of 4759 that it wouldn't ignite right. Have to go to smaller
amounts of something like Blue Dot , but in thin barrel real heavy
slugs go too slow with softball trajectory.. Ed

[cpileri]

Sure, and thanks. The federal load of 1.5oz goes 1050fps, or so. Id have to get out the trajectory calc to be sure, but the 600gr slug epoxied into the csd wad at 1050fps wouldnt have the BEST tranectory. But it wouldnt be too bad for short range work.
Again, id need the math to be certain.
Do you happen to know the ballistic coefficient of that bullet u developed? Admittedly, it will be different w a wad stuck to its tail, but just to get an idea.
Still learning!
C-

[hubel458]

The 600gr 550 bullet about .300 BC. It's semi round nose.
With CSD wad glued to it about .150-180 ..Ed

Those pressures might not be that high with a single projectile as they don't have the set back as shot loads.

Even better!
