RE: blackhorned caused rust
I don't think the Blackhorn folks said anything about letting the gun sight to see if it rusts. I don't do that to my centerfire. I'm not try to be a pain, just trying to be fair.
Actually,hereis what Blackhorn says and pay attention to #2 and #8:
1) Superior Ballistics and Unbeatable Accuracy
2) Noncorrosive and Low Residue
Blackhorn 209 is the first and only noncorrosive muzzle- loading propellant. It is specifically designed to be free of solid and sticky residues that lead tocorrosion with other propellants. This revolutionary feature also assures that Blackhorn 209 will not leave a crud ring that can damage sabots andaffect accuracy.
3) No Swabbing Between Shots
4) Easy Breech Plug Removal
5) No Special Primers Required
6) Not Affected by Temperature or Humidity
7) Uniform Size - "Good to the last shot"
8) Immediate Cleaning Not Necessary
Blackhorn 209 is noncorrosive and virtually free of solid residue. Only a thin film of soot remains in the barrel, which will not harm your muzzleloader.There is no need to clean your barrel immediately after use. However, as with all firearms, we recommend using at least one wet patch of solvent after
shooting to protect your barrel from moisture.
9) Cleans with Regular Solvents
10) Extended Shelf Life
