No the bullet on the left is a .41 Hensley & Gibbs #258 220gr bullet, the original .41 Keith bullet. Keith drew up the design and had H&G cut the moulds for him. Keith was miffed at Lyman due to Lyman sticking his name on their 410459. Keith had nothing to do with designing the 410459 bullet. The bullet to the right is a commercial cast 215gr SWC, however they actually avg 210gr.
