TS Customs built both of my 6/6.5 PRC. A great cartridge.Good to know. I was interested in a larger 6mm to use on a long action. Not sure it's worth it over my 6CM getting 3100 but checking. Something possibly off the 6.5 or 7 PRC case. I like improved cases so that why the interest in the primal. Easy button would probably be a standard 6.5PRC resized to 6mm. I have to make it more complicated though ♂
