If you have a reamer that is fat at the base or your chambering methods allow a "too" large chamber at the base Lapua will even have loose primer pockets.

Butch,
Thanks for the reminder about the reamer, It was not my reamer and I did not check any dimensions, but that certainly could have been an issue. When I set up a barrel in the lathe I utilize Deltronic pins, and I have a Bison 4 jaw independent chuck that I dial it in with. I use a gauge that is .0005 and I shoot for o movement to 00025" movement., then I do the same on the opposite end, then go back to the breech end to ensure there is no change in TIRO! Some day I would like to try the range rod method.

Several have tried the gerdy method and discarded it.
Fact iz
Wilbur shot Lapua brass so many firings (excess of 100) Brass would not die,, so he had to abort it,, and have a brass funeral over a 55 gal trash drum,,,,...
(he would say "old brass ,, you have served me well and brought me many-a-pine board trophy" ,, thank you much ,, but I have to pull the plug,,, good bye) he would then dump it into the barrel. and primer pockets still tite
Maybe not his exact words ( I get disoriented @ funerals) but close

Part of it
Is the already mentioned differences in dimensions. I once had a Bob Dodd action. It was a gun he built for himself then sold and I bought it from the second owner. I tried some once fired Lapua brass and it wouldn't chamber. I called Bob and he told me of course it wouldn't fit the reamer I used to chamber the barrel was ground for Norma brass. I bought some from Ken Livengood and never looked back. It shot 28.5 to 29.5 grains of N133 with no ill effects. That was my experience with Norma brass. Very good! Greg
Is there a reason why more people are not using Norma 6 PPC brass? I notice in the shoots results it seems like everyone is using Lapua .220 Russian fire formed for 6 PPC. If there is a good reason for this, please share it with me.
Thanks,
Jim

the New Norma brass is decent stuff. I have used it quit a bit. There are a couple things to know about this brass if you choose to shoot it. One main thing, and probably what I like least about the brass is the headspace. The headspace of the new norma brass is really short. If I chamber myself a barrel for this brass, I will have to stop my reamer short about .008to .010 sooner than I would with lapua 220 russian. I like a good snug fit on my brass for the first firing. If you don't stop your reamer short and you run your reamer in for 220 Russian, then your norma brass is going to fireform. what I have found if I go this rout, is that the brass will forever grow and require constant trimming. So if your going to use the norma brass, chamber your barrel accordingly. Lee

Skeetlee,
Thanks you may have just solved my problem, that would certainly explain the ruptured cases .250 from the base! I appreciate yor input.

That's pretty close! Truth is, the first time I did that was at Reidsville (maybe Roanoke)...and it was that old stuff that everybody wanted but couldn't get. You had to know what color/tint it was to get the right stuff. I remember thinking I had found some and it didn't last two firings. Of course, I shot it a hundred times but hey...It still worked...the rifle fired when I pulled the trigger. Made a hole in the target as well...somewhere!
That fellow I bought those bullet dies from had ten thousand of those good cases. He wanted too much for them at the time....I thought! Should have bought those cases and not the bullet dies.
