[QUOTE="highdrum, post: 1743965, member: 13732"] Gunwerks took a 375 ruger case, necked it down to 7mm, pushed the shoulder way back and shortened it a bit to create a long necked 7mm Magnum with capacity between 7 rem mag and 7mm stw. This case first came about in 2012 or so. A lot of guys had been wildcatting the 375 rug case, but the guntwerps boys had to put their own twist and give it a neck that's like .350 long. It was new, it didn't quite due what they said it would, lot of brass neck thickness issues in reference to their reamers, guys had to get things rebarreled due to whornady making brass to thick on a lot of cases or you did a lot of neck turning. I think my rifle was chambered with revision 3 of reamer design, that was in 2014 I believe. Noble idea........poorly executed. Take a 7mm blaser case, reduce the taper and give it a 40° shoulder and you'll have a high performance 7mm that's about 88-89gr capacity. I need to sell all my 7mm lrm reloading stuff, thanks for reminding me! [/QUOTE]
