I have been putting something together about the 6x45mm. I have a target rifle (It weighs 14 lb), and a walkabout rifle chambered in 6x45mm. The 6x45mm is a viable option for where I live. I have been testing bullets from 55 to 90 gr. Not all are done yet, but I will be shooting 15 in total. It keeps me out of the Corona bars.
