I am working on a load with 209 BH and a 250 grain Barnes Spitfire TMZ out of my 50 Cal. Encore. They shoot great however the TMZ bullet and Sabot combo is a beeoch to load down the barrel. I have been reading about the Harvester sabots and how accurate they are and how much easier they are to load. I want to try them out but I don't know which ones I need. I have already figured out that I need the yellow ones that are made for the boat tail bullets I just don't know the right size. They make a 40-45, 50-45, and 50-44 caliber. Can anyone here enlighten me on the correct sabot that I would need ?
