Thread: Short barrel magnum calibres?

Righto, Not looking for do or don't rather interested in first hand experience. Who has or had a short barreled magnum talking 20 inches or less plus suppressor and how did you rate it? What calibre and speeds were you getting out of it and what powders were you using?

Currently toying with the idea of chopping the rem mag down but don't really want to cut into into the fluting or getting a WSM and chopping to 18 inches. So hit us with what you have got.
