The powder to velocity math I would wager.What math?
Todays ES was 7 FPS with a 7 round string. Average of 2862 FPS. This is with the new barrel.What kind of ES do you have? The math does seem a little out of sorts but I'm not familiar with the Dasher like I am the CM.
Oh ok. I thought you might have some real ES numbers since you seem to shoot a lot and with that load. Your ES is still probably good. Even still, ES is probably not why the numbers look a little funny. Hard to belive you didn't get more rounds out of that modBB barrel. That's not consistent with every other one I've seen numbers on but there's a lot of factors to that so who knowsTodays ES was 7 FPS with a 7 round string. Average of 2862 FPS.

Your round count and that barrel being shot out. That’s pretty normal Numbers in my opinion.What math?
Well, that was the round count so I’m not sure what to tell you as I keep logs of all of my barrels round counts. Got the barrel directly from Bartlein too as a MODBB barrel.Your round count and that barrel being shot out. That’s pretty normal Numbers in my opinion.
Figured the Mod400XYZTUV barrel would last much more than that.
I’ve seen regular dasher barrels that didn’t last long compared to others give out around 1,100 and they were run at moderate speeds such as 2800-ish. So if this barrel was just a sample that gave out early for the material it’s still good in my opinion since it lasted longer than regular stainless that gives out early. We shall see how this new barrel performs now over time now.Oh ok. I thought you might have some real ES numbers since you seem to shoot a lot and with that load. Your ES is still probably good.

Yeah I'd be interested to know how the next one does for you for sure. I thought dashers were supposed to be easier on barrel life than cm but as I said, there's a lot of factors involved in the number of good shots you get out of any barrel.I’ve seen regular dasher barrels that didn’t last long compared to others give out around 1,100 and they were run at moderate speeds such as 2800-ish.

That's consistent with what others I've seen are getting. Thank you for posting the info.My first dasher barrel is a MODBB barrel and I'm pretty sure she's done now at just shy of 2500. It spent most of its life shooting 112 match burners with varget at 2840FPS. Then the last 1/4 or so shooting 109 hybrids at 2850. The barrel is 23.5" long and used for PRS competitions. Last time out speeds had dropped about 60-70FPS. I did a very aggressive cleaning and the bore still looks rough and not completely clean. I'm going to pull it and start with a fresh tube. Just throwing this out there for another data point. It's my first dasher and first MODBB material barrel, so I haven't really drawn any conclusions yet. But Bartlein is definitely my favorite barrel so far.
Dayuuum!My 400ModBB 6.5 Creedmoor died at about 5000, factory ammo Berger 144 mostly, PRS matches, 2800-2810 fps, M24 contour, 26", 1-8tw, built by Bugholes.
Is it just as accurate?6 Dasher still purring at 2150 rounds
Still shooting a 3/8 group consistently and cleans the same. I recently, at 1800 rounds, checked the lands/jam and it moved about .060”.Is it just as accurate?
Have you noticed anything different like how it cleans or how much have the lands moved?
