The 6UM

[Formidilosus]

Would you consider this to be desirable performance, acceptable, or more of a fluke outcome? You've seen terminal performance from a decent number of these DTACs now, is this common or do they usually fragment?

There are multiple versions of DTAC’s- Nosering and none. Then multiple different versions of Noserings. For the ones commonly available on the open market, this would be normal’ish performance- the bullet starts to yaw, the tip breaks off and it continues fully tumbling through the animal. They do not fragment massively. There are some Noserings that do generally fragment heavily above 2,300’ish FPS impact.

Desirable, acceptable, etc…. Eh. Bullets that consistently tumble, while different than what most have been taught is good or acceptable, does create very good wounds. This makes 16 in animals in the last year, 13 elk IIRC, and all have killed very well. I do like them in elk. Though certainly effective in deer, not my first choice there.

Which do you prefer, 6UM or 33XC?

Both can do the same job. One is just more polite about it(6UM) The 33XC was built for a couple big areas I hunt where I need to see splash. The 6UM can do 98.5% of my hunting.

Impact velocity?

I will double check but I think 2300ish.

The bullet will go faster than I have it shooting now(3250) I was in a rush to kill a cow elk with it. When I get home I will start playing around with other powders.

Why the Tikka action instead of a custom?

Tikka is a “custom action”

Better trigger
Feeds like butter
Short bolt throw
Cheap

I've got a Sako in 300 WSM, handcuffed by magazine length. Given the big game threads on .223, 6mm, 6.5mm, I don't really see the need for a .30 cal magnum anymore.

Got me thinking about converting it to 6UM...

I agree with the bottom half.

If you took it to a GS what would change if you could.

Looks like about the same barrel life as a 28 Nosler .
