Sierra Heavy TMK 6MM Testing

Everything I’ve heard indicates stable. I plan to run it

Ok cool. I’d be doing it at 6 arc velocities.

Funny you say that. I’m so torn on staying with 6 Creed/243 or switching to either 6 ARC or 6 GT. 20” barrel Tikka. I’d prefer to shoot something with lighter recoil to allow me to stay in the scope better. 243 has been snappier than I expected.

Anyone have experience with the relative recoil between the ARC and GT?

GT would be easier cause I can just rebarrel my Tikka. ARC has more factory ammo and less recoil. Can you easily spot shots with the GT in a light hunting rifle? I’ve never shot the ARC or GT

Anybody ran the 6mm 107 tmk through a 1:8 twist? Stabile or issues?

They have been fine for me thus far. 6 arc 1:8 twist 21” barrel. Unsure on velocity with the load, but I would say 2800fps or faster. 1200-2800 ft elevation. I would have to look back in my notes to tell you pressure and humidity.

I haven’t shot the arc in a comparable rifle to a GT, but I have shot my 6BR in a comparable rifle to a friends 6GT. 6 arc is functionally identical in recoil, powder, and velocity to the BR, so I believe this is fairly analogous. In this particular case, the BR and the GT were so functionally close. Between them though, I’d pick the arc for factory ammo availability and support.

The 243 with a 107 and h1000 is definitely snappy! I was surprised aswell, but still fun to be pushing the 107 at 2950ish fps with a 20” barrel.
