You fought in the Civil War, didn't you bfrshooter? jumping

Yeah, sold my guns to the Indians too!

UPDATE: I tried two more types of powder yesterday. HS 6 leads just as bad as the Universal Clays and it was one of the powders listed in the Laser Cast load data. This load chronoed in the low 1100 range.

H 110 left a trace of lead that cleaned up easily. This is a stiff load in the 1350 fps range and is the cleanest load so far. There's something to theory that you need to run these bullets a little hotter.

A couple of observations on the cylinder throats on this gun. You have to use a cleaning rod to push a bullet through. It seems to me that ideally, a bullet should pass through with minimum resistance. Am I onto something here or crazy? Also the throats are quite rough and look like they could use a little TLC via a small hone.

Thanks to Flat top ans Idaho Sharpshooter for their suggestions via a PM. I'm getting closer to success here and will post again when I find what actually clears this problem up.

You need to slug and measure the groove to groove size and make sure the throats are a little larger. That is your first step. If the throats are smaller, there is nothing you can do until they are reamed or lapped. But you NEED the barrel size FIRST.
Let's talk about bevel base boolits. I have worked with many and never found better then dismal groups with them even with no leading at all. None of the bulk BB boolits would shoot like I want.
I took the mold I have for a .357 and cut the BB out of it and tested over and over and each time, the FB out shot the BB.
These were shot at 50 yards, BB on the left and FB on the right. I called the one low shot, open sights are hard at my age. The front sight went too low and the gun went off.

I forgot to tell you to look at the poi change too. Both used the same load but the FB hits higher.

UPDATE TO THE UPDATE: Immediately after my last update, I did a little more research and yes the throats needed to be opened up to allow the bullets to pass through without being resized. I lapped the throats and it helped some.

A little less leading with the H 110 load which is the best so far.

A little less leading with the HS-6 load but still not great.

No improvement with the Universal Clays load.

I think it's time to give firelapping a try. My research is leading me that direction and it seems to be working for other people with the same gn shooting cast bullets.

I like my cylinder thraots to a thousndth over my bore and I will shoot a larger bullet than my bore and I never ever have a problem with this approach, with LBT blue lube

Before you begin lapping you probably want to ream you cylinder throats. "The Cylindesmith" is about the best way I found to get it done. You send him your cylinder and $40 and it comes back in about 2 weeks. In my case he sent me $20 back because it took less time than he expected. Can't ask for a more honest service than that. I'd also recommend the Beartooth lapping kit. At least get their lapping booklet. It covers a lot of territory.

The Cylindersmith

Lasercast says their bullets are 24BRN and it seems like they are just that.

I'm moving a 44mag at 1372fps out of an old Vaquero and haven't noticed any leading in that shooter. But as always every gun is different and sizing in barrels and cylinders are all different unfortunately. Maybe after another 500 rounds down the barrel it will smooth out some or perhaps, as mentioned, take a look at fire-lapping.

I've used Lasercast bullets in 45Colt, 44Mag, 10mm, and .357 and had good luck avoiding any leading. Just my experience.

FINAL UPDATE: I ordered the wheeler fire lapping kit from Midway last Sunday. Yesterday I firelapped the revolver. Giant PITA but the results were worth it.

After firelapping, I cleaned it again and fired 18 rounds of the Universal Clays load. This is the load that leaded the worst. There was still a tiny bit of lead in the bore but not even close to mess I had before. What lead was there, cleaned up easily.

I think I'll try 12 more rounds of the 600 grit and call it good.

Thanks to all for the sound advice given.

This just isn't true. Lead bullet fouling is all about bullet fit first. Most Rugers have very small cyl throats. so the bullet gets sized down, then has to bump as it hits the forcing cone. That lag time, when the bullet is undersized, allows gas to blow by & you get leading early in the bbl like that.
One of my RBH in 45colt had 0.450" cyl throats & 0.451" groove dia. It shot fine, but leaded badly in the first 1-2". I opened the cyl throats to 0.4515" & shoot a 0.452" bullet. The accuracy is about twice as good now w/ almost no leading pushing a 25-1 soft LHP @ 1000fps.
My hunting rev is a RBHBH w/ 7 1/2"bbl. My hunting bullet is a 27grLHP @ 1225fps, cast the same. It doesn't lead, but has a gas check. My practice bullets though are 250grLSWC run at the same vel, plain base, no leading.
Go 0.001" larger than groove dia, match the cyl throats to the groove dia or slightly larger, alloy composition is the least of your issues to 1500fps.
The other issue w/ LC bullets & low pressure Univ. load is they are too hard. The bullet skids as it hits the rilfing & you get leading early. For your lower vel/orssure loads, go to a softer bullet that will not skid on hitting the forcing cone.
