6 um 18” barrel voracity's with 115 dtac

[ike22]

Any one on here running a 18” barrel on a 6um? What are you getting for speed? I had unknown do a barrel action with a 18” barrel. After fire forming I loaded up 66 gains of 570 with 115 dtacs at 60 thou and am getting 3115 fps average on 5 shots. Does any one else have any data?

There’s a 6UM thread that should have all the answers
