The DTECH uppers are not available in the Grendel according to their website. The 22, 6mm, 25 and 6.5 DTI rounds are made from the 6.8 SPC brass which is necked down with shoulder changed 30 degrees.

I had read some on Predatormasters a few years ago about these and dug back a little to refresh memory about the rounds when it came up here this week.
DTACUPPERS do make some hotrod uppers in the WSSM family of cartridges which are cool except trying to find brass is a real pain these days for. Sure those with the WSSMs can make it from the WSM brass but that is a real pain.
