which reloading press?

[Fitch]

Starting with long action magnums and working up from there to even bigger cartridges, the Redding UltraMag is probably the way to go. It's a reloading press designed specifically for what you plan to reload, i.e. the bigger cartridges but with the ability to do smaller ones as well.

I use the RCBS Rock Chucker Supreme and I love it.
