Sierra Heavy TMK 6MM Testing

If it works why change, im sticking to the 107s in my 243.

Because it’s fun to tinker with different bullets for me.

It's the "what's on the other side of that ridge" mentality. You just have to know. So you do what it takes to find out. And who knows......perhaps the 116's will shoot .250" groups.....LOL.

Let's all just "wait and see" what happens.

All of us...and see...what happens.

Lol you obviously just did the same thing with the 107s since they just were released before the 116s. So I assume you had something that "worked" before those but you changed....

Would love to see where you hit pressure using a 116 with 4350 and sc in a 243

Yeah sure, next time out I’ll bring some.
I’m thinking it tops out at or before 41.5 & 44.5

And the 243 is 1:8 instead of the 1:7.5 of my 6CM so that’s something too.

Not really just got this 243, when the 107s were released. I built a load with the 108 Eldm and the 107 tmk at the same time roughly.

Yeah it’s definitely fun! I don’t fault anyone for tinkering, if I had a 6 prc or 6 um the 116 tmk would be a no brainer for me. I’m sure it will also do well in the 6 creed/243.

Eh, the 243/6CM is like the dividing line with the 107/116. Can go either way depending on velocity. But the 116 will likely do better with quick drops, I’d bet at around 2625fps you have the same correction factor across the widest distance at the the widest range of different atmospherics. If you’re doing that, why not take the deeper penetration and edge in BC?

But if you’re like me and most of your 6mm cartridges are below that, maybe go the other way.
