I have looked around a bit for any postings on this bullet and can't seem to find any solid info on starting loads with it. I haven't had a chance to cast any bullets yet with this mold since the delivery of the GB but I intend to change that pretty soon I would be interested in knowing where most folks are starting with powder and where folks are crimping this bullet. I was planning on seating it to the top grease/crimp ring but by my SWAG puts the bullet sitting .510" inside the case. Most of my other cast bullets are usually around .350"-.383" inside the case. I was also planning on getting a modified M die spade machined by Buckshot to expand the brass to take this monster. Thanks for any info you might be able to provide whether actual experience or theory on how to proceed with pressure/seating depth of this cast bullet.
