Still leading

[Outback32]

Well I've read and read and read. Thought I did everything right and I'm still getting leading. Gun is a super blackhawk hunter. I slugged the cylinder at .432 so I sized at .432 powder coat. Loading in a 44 Russian case 240gn Lee mold. Loading 4.6gns of unique. I'm still getting minor leading in the forcing come. This sucks I've got a lot of money wrapped up in this to not be able to shoot them

[eric123]

Does your barrel have a choke point at the forcing cone or where the barrel screws into the frame?

[fredj338]

yeah gotta think the forcing cone is either really rough or you have a choke point from where the bbl screws in.

[reddog81]

Is the leading just in the forcing cone? Are you sure it's leading? Are the barrel and cylinder correctly aligned.

[Tom Myers]

Long 44 Magnum chamber - short 44 Russian case + short Lee bullet = space for blow-by before bullet seals in the throat of the cylinder????

I think it's time to try some castboolit ammo made with 44 Mag cases for that Super Blackhawk Hunter.

[dubber123]

I too would try some correct cases first. I have never cared for short cases in long chambers. That said, I would not be surprised n the least that you don't have thread choke. Its about as common as dirt.

[mpkunz]

Can you put a bore scope up that tube and post some pix ?

[44MAG#1]

Why???? Would you use a case that short in a 44 Magnum chamber????

[Cosmic_Charlie]

Are there tooling marks in the forcing cone? If there are you may as well stop with cast boolits in it until you can get that fixed. It will most likely shoot j-word bullets just fine.

[Outback32]

I will try loading some in a mag case and see what happens. I had a lot of these Russian cases and thought I'd give them a try. I will try to get a pic of the forcing cone also.

[Outback32]

There's also minor leading in a few of the cylinders

[sigep1764]

Hold on, maybe I misread this. You measured the the slugged barrel at 432 and sized the boolits at 432? Shouldn't they be sized bigger for better sealing? Say size them at .434?

[sigep1764]

What to the cylinders slug at?

[Outback32]

Cylinders slugged at .432

[Lloyd Smale]

wheres the leading in these pictures. I don't see any or at least not enough to hurt a thing. A light gray wash in the barrel isn't leading in my opinion. Its when it builds up so that you see rifling filled or accuracy suffers.

The leading is on the top groove. I couldn't get a pic of it . I put pics of the forcing cone so guys could tell me of it needed anything done to it

[Outback32]

I can hammer a bullet flat and the coating stays on.

In my opinion, this is a forcing cone that definitely needs something done to it. I honestly don't think I have ever seen one quite that rough.

[Outback32]

Well the mag cases do not lead at all. The Russian cases lead a little in the forcing cone. I wish the russians would shoot without leading. But thank you to everyone that suggested mag cases it worked. No leading at all.

[Outback32]

I just want to say thank you to everyone that helped. It feels good to be able to shoot boolits that I cast and powder coated. Next is 357 as soon as I get my gp100. I hope that goes well. I've decided il shoot plated bullets in the Russian cases and lead in magnum since that's what my gun likes.

[gnostic]

Try a .430 boolit with a good lube, in a 44 magnum case and see what happens. Normally, the barrel leads when the chambers are smaller than the barrel...

[Outback32]

.430 bullets lead the barrel my cylinders are 432 but that doesn't matter. The boolits I have sized to .432 dont lead in a mag case. That's why I'm happy

[DougGuy]

If your .432" boolits slide into the throats with finger pressure, the boolits and the throats are correct. Nuf said.

The forcing cone definitely could use work. You can go to 4D rentals and rent the kit from them, they have a 20min video showing how to use it. You don't want to make the OD of the fire ring any bigger than you have to to clean it up. This is what a good one should look like when it is cut with the 11 degree cutter:

[Cosmic_Charlie]

I had an sp 101 with a rough forcing cone. I guess ruger thinks it's o.k. to put those out for their customers.

For most folks shooting mostly factory j-words a few times a year they're actually right. Thankfully it doesn't take much to bring it up to snuff for more discerning shooters and nice folks like DougGuy are happy to do it.

[dondiego]

You may be worrying too much about a little lead. A little lead that doesn't continue to build up and affect accuracy is no problem for me. You will know real soon if you get bad leading in a .44!

[44MAG#1]

This sounds to me like the Fable of Henny Penny and Chicken Little and their episode of the Sky Is Falling situation.

Now that's what a forcing cone ought to look like!

[Lloyd Smale]

is it possible the shorter Russian cases aren't being supported and held straight enough to have the bullet enter the forcing cone in alignment. Try seating some bullet out to 44 special length and see if it cures it. Ive shot the Russians in 44 special guns but not 44 mags.

[h8dirt]

Every New Model Ruger 44 I have bought in the last 5 year’s has had thread choke. Swage a well lubricated slug and push it from the muzzle to the breech end and see if you feel it tighten right at the barrel/frame connection. If so, you’ll need to fire lap the bore to remove it.

[Outback32]

I may try to seat the bullets further out. I shot 60 mag rds monday. There was no leading at all I'm glad I found this site.

[Outback32]

I don't know how to quote ppl. But what is 44mag1 talking about fables.trying to say I'm making it up or what kinda confused

[Oklahoma Rebel]

I would just stick with the magnum cases. using a faster powder, you can load them to 44 Russian, or 44spl velocities, and you don't have to worry about blow by and leading, I think you got it figgered out though! have fun! by the way, did you say what model you have?, I have the super Blackhawk stainless bisley hunter in 44 mag, and I love it! I have never shot a manufactured load or boolit through it. I use the noe 432-277 keith style, which casts at 275grs with my alloy, and I size to 431. what boolit are you using?

If I were to guess? I'd suspect the fable comment is a "cute" way of saying lead fouling isn't a big deal.

Myself, I think your question and desire to work out this issue is a good one.

:bigsmyl2:...and I've had Henny Penny chicken, it ain't nothing to write home about :bigsmyl2: LOL.

[JBinMN]

Before you consider firelapping as I believe was suggested earlier, you may want to read about it first here:
http://www.lasc.us/bellmFirelappingBarrels.htm

G'Luck! in finding a solution, but I would think that getting that forcing cone cleaned up & smoothed out would be what "I' would consider first. ( I am not expert on this, but I know a rough part when I see it, I imagine...LOL)
;)

Just saying what some call leading may not be a big deal. Now actual leading may be. Can you tell any REAL difference in your "across the board accuracy"? Are you good enough to tell?
Does it continually build up? Does it level off and stay the same for many rounds? Or have you seen a spot of lead and started worrying.

There is no barrel that will stay spotless even with jacketed bullets. There have been so much yelling about leading I wonder if most are actually getting LEADING or are they panicking when the see a spot or two that never gets any worse.

I have the stainless super blackhawk hunter 7.5 inch. I love the gun I'm loading a 240 gn Lee swc.

[Three44s]

The forcing cone roughness will daunt you until you fix it.

[Lloyd Smale]

me too. I could never see why some get so excited about shooting Russians or specials in a 44 mag. The 44 mag cases can be easily loaded down to the same level and are easier to find and usually cheaper. I don't remember the last time I even shot a 38 out of a 357. Ive got 38 revolvers to do that with and if I want to shoot 44 specials I do it in a 44 special gun.

[Outback32]

Well I had 300 Russian cases and the reloading dies for them gave to me. That's the only reason I tried them. I will just shoot the mag cases

[Lloyd Smale]

Id bet you could find someone that would swap you two to one for those Russian cases in exchange for 44 mags. If not here at any cowboy action shoot.

[Oklahoma Rebel]

Lloyd is probably right, since they probably make the Russians in pretty limited runs, they are bound to cost more than the magnums, maybe try swap and sell ( I think you have to have a certain amount of posts to use it, but I don't think it was very much.

[9.3X62AL]

Fully in agreement with Tom Myers' posts in this thread. If accuracy is sound with castings and the leading problem is resolved by use of the full-length cases, the 11* forcing cone modification may be "Nice but not necessary". That re-cut forcing cone sure looks GOOD, though! :-)

I stopped using short brass in long chambers several years ago. I got tired of cleaning the carbon/lead/lube deposits out of the chamber front ends.
