it seems the topic of the benefits of fluted bolts come up about weekly here. there is always at least one poster that tries to justify the cool looks by saying the flutes give debris a place to go instead of locking up the action. in my opinion, this...

Old school!

Tig'ing one one side of a 416R barrel, just in front of a chamber is not something I would do, nor recommend. Probably would be fine, but I don't think it's worth the risk.

I’m no math magician but if he had the breech and 3” forward dialed in, assuming it is linear, that’s like .026”/inch of deviation. I’m finding that really hard to believe.

Ok, if you you are serious about .6” of runout at the other end, that barrel is being bent in the lathe. I can promise you that. The barrel makers gundrill would have popped out the side of their stock if that is really what was going on.

If they are doing that without bending the barrel, they sure aren’t seeing anywhere near .06” (assuming that’s what the OP really meant) of runout. Probably under .01” TIR at the muzzle.

“The right way” is still debatable. I suppose if you are getting the results you are after, it is the right way. I still think bores are much straighter than the internet makes you believe. My hunch is there are a bunch of barrels being bent into submission between spider chucks chasing a...

Yes.

I’m thinking if ATF is kicking in your door to get a potential “intent” charge, it’s going to be an add-on to a real charge you were already going to prison for.

All if it. That a rifle shot better because of “clocking”. That there is a flatter trajectory due to barrel clocking. That switching scopes between guns is easier because of barrel clocking.

I’m a bit skeptical of that.

Water based coolants have a lot of maintenance involved, especially with machines that sit more than are used. I’m not sure there are any advantages of a water based coolant for chambering barrels on a manual lathe. Rigid Dark works so good just applying it with a wash bottle, I think I’d stick...

Some people set up their barrels so the muzzle and throat are running true when chambering. There would be nothing to "clock" or index at that point.

If the bore is truly curved, you can only have it running concentric at two locations without bending the barrel. Each builder needs to decide which two locations those are.

i see no reason why you couldn’t have the throat and muzzle dialed in with the TBAS. Maybe after the throat and muzzle were aligned with only gravity acting on the muzzle, you could then use a spider to hold it in place and attach your flush system. There’d be very little stress on the barrel at...

I’d like to know how many people have verified their muzzle TDC while set up on the lathe cutting the tenon/threads/chamber is the same TDC while being hung from the receiver threads, free of the stress of being jacked around by chucks and screws 20”+ apart... Maybe do all your chamber end work...

I've got a B&S 599-579-4 and a Mitutoyo 505-742. I feel the B&S is much better made but I like the Mit better because of the drive wheel.

The "curvature" in a barrel is no where near as extreme as some people make you believe. There are ways to fit a barrel where it doesn't matter. There are also ways people use that I personally feel have a high possibility to exaggerate the runout at the muzzle end, which would be a good idea...

What's the favorite stencils for electrochemical etching? Are you having them made or making them in-house? If in-house, what's your method? Something better than a typewriter?

Since the OP was asking about having a bolt fluted, it would be highly likely to be a factory two lug bolt. On a two lug action, where most people flute the bolt body, there is the ejection port, magazine port and raceway leaving minimal actual bolt body to receiver contact in that area. There...
