To me, no leading is acceptable, it is hard to clean and affects accuracy. I prefer to buy lead bullets with the JM Hi-Teck coating (Leatherhead Bullets among others). With the coated bullets you get a much cheaper bullet then jacketed but no leading.
The slight bulge is normal. You want to make sure that you are "over-caming" in the down stroke of your press. Lots of people screw their die in until it touches the shell plate. What you want to do is screw it down a bit further after touching so that the die is encasing the web. For me it is more of a "feel" but somewhere around a 1/4 to a full turn should be right. A Redding G-Rx die would solve your problems. I will pm you, I have a brand new one that I don't need. The G-Rx die pushes the brass completely through the die and eliminates any bulge.
You should pull your barrel and use it as a case gauge on both your sized, unloaded brass (to make sure that your dies are set correctly) and your loaded round. Once your dies are set you don't need to case gauge empties any longer. If your round passes while case gauging using your barrel and your OAL and crimp are right, the gun will run.

Don't worry about the KKM barrel, KKM makes a great barrel. If you don't like it and want to sell it, your original barrel will work just fine with the Hi-Tek coated bullets.

Are you using manufactured or casting your own? Are they pre lubed? Without a visual I can't say much for excessive leading. I run lead semi-wadcutters in my single action army and see very little leading after 100 rounds. Many factors come to play how well the barrel is lubed, how well the bullet was lubed, the bullet design all can contribute to leading. I can't say if problems will arise as I've never had any more than would from a jacketed soft point left behind. More importantly is can you clean it out.
A local guy is casting these. They are lubed but not gas checked.

Years ago when everyone shot lead the common thought was to keep the bullet around 900fps or so. Leading depends hardness of the lead, speed of the bullet and also (to a degree) the type of powder. You are running these bullets too fast.

I thought the point of a fully supported chamber was no bulge? I talked to KKM and they said send it back and we will send you a new one, they thought maybe the feed ramp got cut in too deep. Anyways, they seemed to think that it shouldn't be bulging. Also, I'm using a forster press so no camming over. The rounds shoot fine in the gun, that's not the problem. However, I wish I would have seen your post earlier as a couple days ago I ordered the same G-rx die. Finally, if the new barrel doesn't solve the bulge problem I will just use the G-rx die and keep going. Thanks for all the help.

This is what I am loading.
It doesn't look like they're lubed? Is there anything in those grooves? Kinda hard to tell in the picture...

They are lubed, it has a very slight reddish tint. Gets my fingers kinda sticky.Is he running them through a resizer after he casts the lead? Is he quenching them in water? I make lead bullets for my 357 and I found after adding gas checks the leading issue went away.

It comes out on a Brinell hardness scale about 14-16 hardness. I will drive these bullets up to just under 1000fps without a gas check. I will go up to about 1800-2100fps wit a gas check. I have some leading issues, but nothing that is not manageable. I use a lube I get from Canada called Dragon Lube.

Another question is do you know what size your barrel is? A general rule with lead is that the bullet should be sized .001 to .002 larger than your barrel. Undersized bullets can leave leading from the gas being able to cut around the side of the bullet by the bullet being undersized. Hard lead compounds the issue by the bullet not being able to slug up the base to create a better seal.:yeah: Slug your barrel by using a wooden dowel to push a bullet threw your barrel. I've found most barrels need a larger cast bullet than cal size. If your bullets are too small it will lead no matter what you try. This should be step one with any cast bullet in any gun
