Lapua does not drill their flash holes

I guess the real question is why can't everyone else make them as good?

Quaility control and die sharpening isn't cheap, but Lapua is committed to manufacturing the highest quality brass anywhere! And their customers demand that, that is why they have that reputation and maintain that reputation,,, details its all in the details! I don't know the specifics of this industry but having been in manufacturing I know process and that is what it is all about, the same goes for reloading!
 
I could care less how they manufacture their brass. The primer pockets stay tight. I have wished for years for them to make 280ai brass. Seems more their style than 300 Blackout. Is the 300 Blackout used to form something else?

Tim in TN posted that he had a special 280ai reamer done for 30-06/280 AI Lapua brass. Is this needed? I may reach out to him. I think he lives about a mile away from me.

you can use it in a .280 or .280 AI chamber without major issues,,,(contrary to what some claim) I have done it for years,,,,I also have a reamer desighned specificly for the shorter 06' brass,,,,I use it when chambering a new bbl,,,,but the 06' brass will work with an existing chamber (it will be ~.050" short--no problem) ,,,Roger
 
I too have cut the burrs from the flash holes of Lapua brass. But it was minute compared to domestic brass.

I could NOT care less how they do it. Drilling, punching, laser beam, or shooting the flash hole in. And as part of my regular practice with new brass I always stick a deburring tool in to clean if anything is there, it's a one time operation and simple. And I don't care how any other manufacturer does it either.
 
Compared to others Lapua's burrs are miniscule. I recently did 100 rounds of .17 Fireball brass and could have used a milling machine. :(
 
Recently I have done several boxes of .222 and 6br and found the flash hole to be 99% clear 0r burrs
 
Burrs around a punched hole are a function of pin to die clearance, and type of material punched. Small pin and/or big hole in die = burr. With wear on either, burrs will get more prominent. From my perspective, flash hole burrs would be luck of the draw on the setup man, the tolerances kept on the punch and die set or how long before someone changed out the tooling.

So I have no idea why every one says that Lapua drills their flash holes rather than punching them. I would actually like to know why. I listened to the episode where Kevin Thomas for Lapua USA was interviewed on this podcast, Ep8 and in it he clearly stated that they tried drilling flash holes but went back to stamping them. IN short Lapua does not drill their flash holes. They stamp them out with a punch. He talks about it 23min into the podcast episode 8.

If this is a hot topic please try to keep it civil.

As Hillary Ramrod Clinton once said, "At this point, what difference does it make?":eek:
 
My new Peterson 6.5 CM brass has no burr around the flash hole and looks like it could've been de-burred, it's that clean. Inspecting the flash holes with a 10x loupe I can see they were punched with an excellent fitting and sharp punch and die set. Coning of the flash hole is virtually non-existent with good clean sharply defined, cylindrical walls.

I recently tossed a batch of FC brass (223) where the flash holes were off center by at least a half a hole diameter, and when cross-sectioned, it was so v-shaped it looked more like a rocket nozzle cone than a flash hole. By comparison the Peterson brass looks like state of the art manufacturing and is at least on par with Lapua brass.
