.452" Round Nose Bullets – 228 Grain (Item #: MB45CC30)
 
These .452" diameter, 228-grain round nose bullets are purpose-built specifically for shooters using cap-and-ball revolvers equipped with .45 Long Colt conversion cylinders. If you’ve been frustrated trying to figure out which bullet will actually work in your converted revolver, the guesswork ends here—this is the bullet designed for that exact application.
 
Unlike standard .45LC bullets intended for modern cartridge firearms, these are not heeled bullets. They are a true full-diameter .452" projectile that fits properly inside the cartridge case rather than relying on an undersized heel. This allows the bullet to be seated deeper to compress black powder or substitute loads, just like original percussion-era ammunition. Most importantly, because they start at the correct diameter, they will not be oversized when they leave the conversion cylinder and enter the barrel—a common problem when using conventional .45 Colt bullets in conversion setups.
 
These bullets are engineered to function correctly with Howell’s Old West Conversion Cylinders and similar drop-in systems. Their classic round-nose profile provides smooth chambering, authentic appearance, and reliable performance when loaded into .45 Colt brass. Paired with quality cases such as Starline .45 Colt, they create safe, consistent, conversion-appropriate ammunition.
