I'm getting a Remington 700 Sendero SF 338 RUM and I'm looking at some dies to reload for it. On my twin Remington 700 Sendero SF 7mm STWs I use a Forster Bench Rest Full Length Sizer Die and a Forster Ultra Micrometer Seater Die. I really like them and get great results at the range with my reloads. I do not think Forster makes a Bench Rest Full Length Sizer Die or an Ultra Micrometer Seater Die for the 338 RUM. So I have been looking at Redding dies and in particular the Redding Type S Match Bushing 2-Die Set and the Redding Competition Bushing 3-Die Neck Sizer Set. Redding Type S Match Bushing 2-Die Set 338 Remington Ultra Mag Redding Competition Bushing 3-Die Neck Sizer Set 338 Remington Ultra What would you get? Also, I can't figure out if the Redding Competition Bushing 3-Die Neck Sizer Set resizes? I also have never used a die with bushing in it so can someone instruct me how they work? Do I need to buy the bushings separately and if so where and what size? Thanks!
