Gee I think there aren't many manufacturers that don't make something in that calibre. Lots of options here in Aussie, just not sure what you can get up your side of the equator. They do keep rattling on about banning some stuff down here and that is one of the calibres that usually come up. Shot a Bullpup bolt action design with a muzzle brake (with and without the brake on)a couple of weekends ago. Didn't seem to unpleasant without the break either but then again I was shooting my 458 WM.

I think you should have some fun doing local research you might be surprised what is out there
