Thread: Max fluting depth

what material. ss or CrMo?

pity the barrel is stuffed . . . be hard to measure success, unless you judge accuracy didn't get worse, it didn't blow up, it was good practice as good enough

look forward to hearing how you get on . . on here or via the News

good luck . . . R

Barrel is standard hammer forged brno. As stated above the barrel will be subjected to proof loads and will then be retired to subs only. The bore is severely pitted and very little rifling remains, thus the blase attitude towards it's survival. I'm not going to be a dumb arse and shoot full house loads from the shoulder after the job. Ball end cutter will be the go as i'm not prepared to fork out hundreds for a dedicated multi tooth fluting cutter. First thing is first, removing the barrel (mill bed isn't big enough to accommodate both barrel and action). Time to draw up a wrench

have you looked at just lathing it down to make it lighter?
brno barrels are pretty light to start with but doing this will shed alot more meat, and like you said the barrel is fucked anyway

and basically fluting is done to increase surface area while maintaining rigidity and shedding a little weight
rigidity equals accuracy to a certain extent
heat shedding by increasing surface area isnt really something valuable to subsonics as they dont generate fuck all heat


I understand if this is just for shits and giggles but if you want max effect then going down to number one or smaller profile would be more effective
