Thread: 168 TMK in 308 load development

Have recently finished my very basic load development for the 168 grain Sierra tipped match king getting pushed by 2208 in my old Tikka t3 .308 with a 22” barrel and DPT supressor. Before starting the load development I had a bit of a look on here and noticed there wasn’t much information about anyone running these TMKs in a 308. Thought I would throw up my results, might be of Interest to someone considering these projectiles seem to be reasonably readily available still.

Did a rough ladder test from 42 grains through to 46 grains while trying not to waste too much powder on paper. These were at a COAL of 2.110 off the ogive. This was as long as would fit in my standard tikka Mag. There was nothing extremely accurate at that length but 44 grains and 45.5 grains looked promising. I started seeing slight pressure signs at 46 grains.
I then loaded up a few rounds at 45.5 at different seating depths

2.095 OAL gave me just over a half inch group. I loaded up another 6 at that. Another 3 shot group at around half an inch. That will do me! After shooting at 400 yards to work out the drop, shooter app tells me these must be going around 2690 FPS.
Good to go
