The 6UM

Nose ring dtacs have notably less BC vs the standard non ringed units. I have shot prob 6k of the standards, they have all been 310-313g7 depending on rifle. The nose ring is right around 295-300g7. There are lighter bullets with less bearing that hang with that g7 bc range. I'm still waiting to get my hands on some deep cut dtacs to test out next year in the 20in 6saum. 3150-3200 should be doable as my 24in barrel ran to near 3500 before pressure.
 
6UM Brass is here and shipping. We didn't get as much are we hoped so don't wait if you need some.

They are no different than any other animal here they have to be managed and it feeds lots of children here.

There is something special about the necked down 6.5 SAUM case and the 115 Dtac NR. The 6UM is a killer!

The shot was 50 yards the PH told me to put it right at the bottom of the square. Unfortunately for giraffes they are born with targets on them. The bullet went between the ribs broke apart and took out the top of the heart and damaged quite a bit of the lungs. The bull was down within one minute of the shot. The PH said “that was not what I expected” and most Giraffes take one to three minutes to go down and more than half take multiple shots. These animal are beautiful and huge.

I’m on my 3rd night of trying to read this thread front to back, just soaking all of this in. Just got my notice the brass is on its way. I’ve had no questions on the cartridge up until this point… but, I must know how giraffe tastes after killing it with your own baby? I’m guessing pretty sweet…
 
My brass came in today as well. Ordered a .272 bushing and 100 108 eldm's for fireforming. How fast do y'all think I can run those out of a 7.5t before I start to have issues? Will they hold together if I keep the spin rate under 310k?
 
Brass is in, chamfer debur, brushed necks, leaded 210M with 57.5gr H1000 and Coated NR Dtacs to fireform. Loaded OD is 2755-276. That's gonna likely need neckturned in my 279nk chamber, we'll see what happens once formed up.

What do you like for min neck clearance hunting? That's part of where I screwed up on my one custom reamer order. Shouldn't have listened to the bench guys!
