45 cal long range cast projectiles

[Plasmaboy_AU]

Hi everyone, Im looking for some 450 - 500 grain lead projectiles for a 45-90 High wall rifle. Im after a projectile thats shaped for the "Creedmore" style long range shooting .. that is, a pointed bullet, not the usual flat nose 45's available for lever actions. Coated would be good too ( such as is done with the westcasting and Hawkesbury brands ) Can anyone give me pointers of where to search?

Thanks
Andrew Smith
