+1 on MBC. Im running 158grain 18bhn's @ 1450 FPS and I get little, little leading. Face it, your going to get some leading, and its unacceptable, go back to jacketed-
Well, I heard assumptions are the mother of all mess-ups. I would estimate that various comments about Missouri Bullets posted on THR are based on hundreds of posters who have used quite a number of bullet/powder/charge combinations and fired them in hundreds of different firearms. Statistically, I think this is large enough sample size to "objectively" evaluate leading issue of 18/12 BHN MBC bullets.Jinzoningen80 said:I'm am merely using this open forum to relay MY specific experiences with MY specific guns using SEVERAL missouri bullets ... I tried 5 different types of their bullets. I've used them in 3 different guns ... I'm not trying to overexaggerate the discrepency here either - yes i HAVE gotten leading from other brands of bullets and yes i HAVE minimized leading with missouri but it was a lot harder to do and it is always present
As I've said, i have no quantitative measurements of hardness or anything else. I base my assumptions on my experiences.
Recommendations that reduce/eliminate leading are often posted based on actual experience with particular pistol/caliber/bullet weight/bullet profile/powder charge/OAL to help the reloaders requesting information.Jinzoningen80 said:I want to help the new reloader who might come here looking for guidance and find your site and try your bullets. He may invest in your product and spend a lot of time and money trying to get them to work and end up like me, with a lot of lead to clean. He may then get frustrated with lead bullets and give up.

Cast bullet hardness, specifically the hardness of the various alloys used to make cast bullets, has raised a lot of questions and confusion lately. A very common misconception is that leading is caused by the bullet being too soft and the lead gets stripped off or abraded away from the bullet's bearing surface as it passes down the bore. This misguided belief leads many new bullet casters to turn to expensive alloys like linotype, and/or elaborate heat treating methods to harden their bullets, thinking that this is the only way to prevent leading.
There are very, very few revolver applications that require a BHN of over 20. In my experience, revolver leading can almost always be traced to some other factor (inadequate lubrication, improper sizing, barrel/frame constriction, etc.). Only very rarely is barrel leading caused by the bullet being too soft. In support of this claim, let me point out that many muzzle loaders prefer bullets cast from 30-to-1 alloy (which is quite soft, BHN of about 9) and these smokepole slugs are routinely driven to 1300-1400 fps. In addition, high-velocity .22 Long Rifle ammo uses an even softer bullet at over 1200 fps (and if a .22 leads, it's a gun problem, not an ammo problem). Elmer Keith's favorite cast bullet alloy was 16-to-1 lead/tin, which has a BHN of only 11. This is the alloy that gave a roaring birth to the .44 Magnum using plain-based cast bullets loaded to 1400+ fps. Properly loaded and lubed, Elmer's alloy will leave a magnum revolver barrel shiny and clean after a long day shooting.
Lead Head, did you shoot the different powder/charge loads at the same time? What pistol, powders and charges were you using? This information may help us help you decrease the leading in your barrel.loading three different powders from max to under minimum loads and they all leaded up my barrel
