It is a dreary, snowy day in upstate central NY. So I busied myself creating something I hope is useful. I am attaching a chart I made, for IMR Trailboss powder. It is for a Lee Autodisk. I calculated this chart using the published cavity volumes from Lee and VMD value as stated by IMR. Hope this helps some of you. You may send me gratuities of 38 caliber lead bullets if you wish. Have fun.
