Anyone shoot a 6/7.5 x 55 Swiss

I need forming information for this wildcat. It shoots 105's at 3300. Any help, please contact me at randallcullinan@yahoo.com .

Are maybe a 6.55 x 55 necked to 6 x 55 Swede, but that would be faster then 3300.

What I think he is asking about is the Swiss 7.5x55 service round necked down to 6mm - never heard of it before though.

The 7.5X55 and 284 Win have nearly identical case capacities. (That's why .30-284 is a rare beast - it's easier to use the factory 7.5.) So, look up 6-284 and you'll find everything you need to know on possible loadings etc. As very strong and good quality 6.5-284 Norma and Lapua brass is readily available, dies and chamber reamers too, it's also easier to go down the 6-284 route than 6/7.5X55mm.
