Hello everybody! I´m very pleased to have found this great website because I have lots of things to learn because in my country, it´s very difficult to practice long range shooting and that is why I don´t have here much information. I have a tikka M65 chambered in 300 win mag and I´ve just started to reload my own ammunition. I am using remington brass, winchester prime, norma MRP powder and hornady A-max 208gr bullet. Any tips? I don´t know exactly which bushing I should use in my redding die, which one would you recommend me? I´ve measured the neck of a loaded cartridge and obtain .320, is it posible?( I say this because I´ve read in this forum that 300 win mag diameter is about .334 more or less) Am I measuring it wrong? Thank you!!
