Beretz: With guidance from Dober and Docbill on here,plus reading about everything Hagel and Page said about the cartridge,I built a 7 Mashburn Super about 2 years ago now.
I have been very happy with it,and have found the case easy to work with and a slight tick up from the smaller 7's when it comes to the heavy 7mm bullets many seem to like today.
There is no practical reason to have a Mashburn today, and put up with the inconvenience of the wildcat,especially since the gains over common factory stuff like the Remington,Weatherby,or WSM are only in the 100-150 fps range.
OTOH, if you want something a bit different that really works with heavy bullets,have an interest in cartridge history and development,like wildcats, and are bored to tears with "common" 7 mags,the Mashburn is a fun project that delivers the goods.And after you have one, those "other" 7 mags may well cease to have a reason for hanging around....they won't be needed.
After all, this is, or should be about fun and games anyway.
