107gr .264 TMK Terminal Performance

Looking to potentially use these in a lightweight shorty 6.5 Creed. Curious what others’ experiences have been with these bullets on big game?

I've used the 107 in a 6.5 Grendel and it was fine. My sample size was maybe ~8.

I think the 130 would still be better even in a shorty Creedmoor though. That bullet is very good.

I am considering the same. I have the 130’s if I can get them to fit in my Grendel. If not I’ll take the speed of the 107 as I view my Grendel as a 300yrd set up

Yeah the 130 would be my choice otherwise. Probably the way to go just because of how proven it is. I’m sure I’d be giving up some terminal capability (especially on larger animals) going to the 107s - guess the question is how much.

My thought was that if the 107s aren’t too far behind the 130s, it could benefit me more to get recoil level down and gain some extra velocity with the short barrel.

What kind of velocities and what animals?

What kind of velocities and what animals?

Impact velocity from 1900-2400 fps. Small Texas whitetails and big Texas hogs.

What did you like or not like about the performance of the 107 TMK? I’m doing some load development for a new 12” Grendel SBR right now and it seems like a natural choice for that.

It was fine. A little on the messy side, I probably wouldn't want impact velocity over like 2400 so I won't ever use it in a cartridge with higher velocity than a 20" Grendel, at least for anything I want to eat, but I bet it'll hold together better from a shorty and work really well.
