I'm 57 years old. Like to do many outdoor activities. Fishing ,hunting,hiking. I've been reloading since 1980. I work for Boeing as a Tool Grinder. I Fabricate any tool a machinest will use to make a part. Messure things in .0001" every night. I'm interested in making a load for my 300 remington ultra Mag. I bought one a couple of weeks ago. Remington 700. If any one has developed a load and could share the recipe for me to play with please do. I'd like to use a heavy bullet. 200 Gr. But I'm open for anything that shoots tight.
