6 Dasher No-Barrel-Cleaning Test

[Brucebarker024]

How do you think this chambering will compare to say a 22creedmoor suppressed, in terms of powder burnt for bore size etc.

Which will be more overbore… saum or creed?

Is your saum suppressed?

Honestly I haven’t looked at the overbore comparison but I imagine the 22 creed is more overbore.

My saum has been suppressed for the last 200 rounds. Before that it was just a brake.

Made it across the 2000 round line. I'll keep shooting it as my match rifle but with 105 Hybrids till I'm ready to switch to the next barrel, and am keeping 100 rounds worth of the current lot of 109 Hybrids and Varget to test as it gets further rounds on it. Funny enough it finished up with the single tightest 20 round group of the test. The velocity spreads and vertical at distance do seem to be creeping up.



Got my scatter plot working. Note, at 500 rounds there is a step change of ~ 20 fps less when I stopped jamming the bullets. At 1332 there is a step change of ~20 fps more when I switched to a can from a brake.





And...if you'll forgive the brag, this barrel has accumulated it's share of regional PRS & WPR match hardware along the way:
