6 UM Reloading Thread

Let us know what you end up with. With a new throat, that looked achievable with my 24" Bartlein numbers. After chopping to 20" and 320 rounds down the tube, I just shot 62 grains with a 115 DTAC and it's only at 3000 fps. Very low pressure though, I'm going to push that up quite a bit and see what it will do.

I’m sure it’ll be a couple months before I can update, I can’t remember what my gunsmiths lead time was. I’ll make sure to post up where I land though.

Anyone used cci 250’s instead of the federal primers? I’ve got a few thousand of the cci’s but my barrel is about 10 weeks out and was gonna just casually keep looking for the Federal primers and some n570 locally to keep from paying hazmat and shipping.

I’m using them. They work fine.

I'm using them as well, with good results.

Anyone have any beta for a load with H1000 and 108/109 elds? Have a 19" 6UM30 barrel coming. Hoping for 3200.

Using the search function, couldn’t find anyone with a 16” barrel. Anyone have 6UM velocities numbers for a 16” barrel?

Had them up to 3340 in a 22" +P barrel, and almost exactly the same in a 24" with a normal throat. 3200 is going to be asking a lot of a 19" barrel. 3100 is more realistic.

Did you ever try out Retumbo on the 115 DTACs or anything else? I've got plenty of Retumbo and H1000 and am wary of N570.
