For rifles, this 90 grain #1535 bullet was designed as a medium-velocity bullet to preserve valuable fur pelts. It has a heavy jacket that does not deform at medium velocities in varmints or small game, causing minimal damage to valuable furs. It can be used in the 6mm Remington and 243 Winchester. It may be used in magnum cartridges, like the 240 Weatherby Magnum, but it should be loaded to about 2700 fps to preserve valuable pelts.
In handguns chambered for 6mm cartridges, the 90 grain #1535 FMJBT bullet performs with good efficiency for the same purpose. It is an excellent choice to minimize pelt damage.
