That 107 is an aggressive design for sure.

Left to Right:
107 TMK
108 ELDM
109 ELDM

Informative -- thank you.

I suspect the #397139 (109/110gr) seating stem might be a good fit for these.

I have a forster ultra seater in 6CM and it left no marks.

Anxious for multiple accuracy reports on the 107s. They look really intriguing…

Here was my (cherry picked best of course) of my 7 shot groups. 16.5” 6 creed. Shot three 7 shot groups and had seen enough to know the bullet works real well. Largest group was .85

Has anyone seen any load data from sierra on these? Can’t seem to find anything. Looking for 6 creedmoor and 107’s.

I was going to start with 108 data then match the ogive location or mag length whichever is longer since the 107 looks to have the ogive pushed back a little compared to the 108’s. Should allow a touch more powder or less pressure.
