Lapua does not drill their flash holes

[retired]

i think most do not understand how precise a "punched" hole can be.
lots of parts are made by forms of punching and come out precise.
some times based on the material they are tumble deburred
i have bee quite pleased with the brass i buy from lapua.
the "burr" on a lapua flash hole vs at debris on a winchester flash hole,
id night and day difference.

As Hillary Ramrod Clinton once said, "At this point, what difference does it make?"

Just picked up one of lapuas reloading books. It was pricy but has a lot of good info in it. They dedicated one chapter to how they make brass. In it they clearly state that they punch them. Its laughable that these rumors get started by arm chair know it alls.

A lot cheaper to punch. Drilling brass with HSS drills requires specially ground cutting edges to prevent the drill bit from being pulled in to the material. That and you're looking at drill motors running expensive carbide bits in the neighborhood of 5000 rpm.

People think they're drilled because they look drilled when compared to domestic brass, which will typically have a huge burr - about as big as the hole. Lapua somehow manages to put the hole there without leaving a massive chuck of brass on the inside edge.

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.

I guess I’ll have to take my borescope and start inspecting the inside of my flash holes to check up on the condition of the newer brass

A Helen Keller reference, despite her being deceased nearly 50 years now, and I'm betting most forum members -- at least those born after 1970 -- don't know who she was.

Unless you LIVE in or near alabama

Know why Helen Keller always wore yellow socks? Her dog was blind too.

Hellen Keller was alive when the thread started. Lol

I feel like i was listening to a tattletale or something. Ive never heard of a flash hole being drilled by anybody in the know. Can you imagine the production cost on that?

For those that don't know, Hellen Keller was the chemist that invented the blue liquid barbers soak their combs in

Don’t know if you were trying to be humorous I could not find that what you claim anywhere maybe you could show me where she invented the liquid we soak our combs in

It is of my opinion that Helen Keller was more courageous and strong the most all of us I could not have done near what she did with those limitations and find her name used in this post disrespectful and I don’t even live in Alabama

I just cant stand to see false info being preached as fact.

Any thought about calling Lapua and getting the fact/s straight from the horse's mouth ?

Don’t be so darned sensitive.

Live in, born and raised in Alabama. My wife is from the Shoals/Quad City area.

I load the cases and shoot! If they shot any better I'd have an orgasm every time I pulled the trigger!!

Laughing out loud!!! LOL

Lapua can make mistakes too

 

[TAJ45]

I have seen plenty that are not clean inside. I have also seen D shaped holes, which i would think is impossible if drilled. Matt

Ever hear of a Watts drill?
