6 UM Reloading Thread

[Odd1out]

I've seen anywhere from 600 to 800 round count for barrel life on the 6um. I'm wondering how many reloads ppl get from the adg brass. I want do a 6um30. Just trying figure a rough estimate on how many pieces of brass to get to cover my barrel life.

I’m getting an average of 5 firings of 6UM/40 before retiring them. So far it’s all been 6.5 saum brass I’ve resized and fire formed. Not sure if the ready to load 6/30 might go another firing

I have burned down three barrels for science. The average is 690 rounds.

My average is five reloads before I lose the primer pocket.

Different suppressor.. Used the Dead Air Sandman Long (That weighs about 40 lbs lol)

Any determination on what was causing the flyers?

Anyone load 115 Bergers? Still 66 grains of n570 I'd assume?
Got DTacs. But Bergers are easy to come by.

Does anyone know what the velocity limit is for the 115 dtac?

 

[ACHILLES]

Seems like guys are successfully running 3400fps in longer barrels with a 7.5 twist. That’s 326k rpm but I doubt the 115s will take much more rpm’s than that in a worn barrel.

 

[The Fish Box]

I’m currently a little north of 3,400 fps and was just wondering how they will like that when the barrel gets a little rough.

 

[ACHILLES]

Well I’ve had a positive experience with the 25cal 131ACE also made made Sierra.
One of my barrels had 1320rounds on it running 3170fps in a 7twist which is also 326k rpm. And I’m still running that bbl just shortened it.

Not exactly Apples to apples but might ease your mind a little.

On our 30” comp rifles, we hit 3600 fps with no issues with an eight twist
