Has anyone killed with the 6UM and the Barnes 112 match burner?

Probably not a good combo. The Match Burners fragment violently at 2,800fps. I would not count on them doing well at 3,300 fps.

Having said that, I’ll shoot some through mine when it’s finished.

I’ve got everything ready to send to um and get one spun up.
Is the 115 nose ring Dtac N570 combo the one to go after?

For now it is. I will be trying the 103gr ELD-X and 108gr ELD-M heavily, as well as the 100gr PVA Cayuga. My guess is that the best currently available will be the 115gr DTAC NR, and the Hornday 105gr HPBT for most users.

I know you’ve answered this before so forgive the old memory but is the 109 eld-m substantially different than the 108.
I have a bunch and they’ll probably be my fire forming bullets.
at 6cm velocity I can’t tell a difference between the 108 and 109 in deer and cow elk anyway.

Functionally identical.

For you or anyone else with experience how does the dtac perform in mule deer?

They work fine. Penetrate 6’ish inches before yawing.

2,400’ish FPS impact

What is your twist going to be and estimated velocity with the 103/108?

I just finished the podcast about the 22 creed and Hornady reps were adamant about keeping rpm’s down to 300,000 or less.

1-8” twist, 3,300-3,400fps MV. They’ll be right at 300,000 RPM.

Man I'm super curious what this 6um and a 87gr absolute hammer could come up with as far as MV

.243 Cal-087gr Absolute Hammer™ - Hammer Bullets

An Absolute Hammer™ for a 1-8" or faster barrel twist. This one will run great in the newer 6mm rifles and customs with fast enough twist to fully stabilize this one. This one has enough retained weight and shed weight to be very effective on big game. Pair that with higher than expected...

Fast. But completely opposite of the purpose. A 22CM with a 77gr LRX will do that.

What exactly is the purpose? Pardon my ignorance, my first thought is always monos since I primarily hunt deer in CA.

Light recoil, great wind and elevation characteristics
Easy to spot impacts and devastating terminal performance. So the opposite of a mono

The easiest to shoot, highest hit rate combination from 600 to 1,200 yards, with the longest danger space possible.

Man that’s a sweet looking barrel!

The Nitride turned out slick! Just need that freakin barrel.

How would you say it feels compared to a non nitrided tikka? I am seriously considering sending mine off but would like to gather a few more to cut the cost down if I do end up going through with it.

Reloading thread is updated with results from the 24" Bartlein. The load I've settled on is 67.3 grains of N570, 215M, 2.890 COAL which puts me .060" off the lands. Velocity is right at 3400. 66 grains shot well at 3340 too. I'll be taking this load out to 1k tomorrow so I'll have an update after that.

 

[Ryan Avery]

Almost there!
