.69 Kammerlader Bullets

[hobbler]

Has anyone here used tried the Accurate Molds Kammerlader designs in muzzleloaders?
Or any other solid base designs?
Have results to report?

I've never heard of anyone using a Kammerlader design in a muzzleloader in the N-SSA. The only solid base designs used here in muzzleloaders are variations of Ritter von Lorenz's compression bullet, generally [and incorrectly] called Wilkinson bullets in the N-SSA. Assuming one had a slightly overbore diameter Kammerlader bullet, the ridges on the lubrication grooves appear to be too thick to engrave in loading like Lee's REAL bullet design. If the bullet is roughly bore diameter, one needs to expand or compress the bullet somehow to take the rifling. If one had a weapon with a Tige in the breech, like some of the French design rifle(d) muskets imported during the Civil War, one might be able to expand the Kammerlader bullet enough to take the rifling by smacking it repeatedly with a heavy ramrod when it was seated on the Tige in the breech of the barrel.

Yes sir, a maxiball by any other name would smell as sweet.
With as short of a bearing length as that kammerlader design has it would probably need to be sized with zero bore clearance in order to maintain alignment, to avoid having flyers from the base sometimes being cocked and out of being perpendicular to the bore. How much FFFg was needed to expand it would of course depend upon the rifling.
I've only used lubed and paper patched hollow base designs in the .69. An expanding solid base bullet is tempting to try out.
