Converting Lapua 6 BR brass to use in a Alpha chamber?

[TackDriv3r]

I have 200 pieces of Lapua BR brass 1X fired, can I convert 6 BR brass to 6 Dasher that had the chamber reamed with an Alpha reamer? What are the pros and cons?
What are the steps taken such as trimming, powder to use, etc before firing a 6 BR case in a Dasher chamber?
I never had done this before.

All I did was fill a case with 30 gr of Varget and set a bullet into the lands about .010 , held it with a bushing size .003 under a loaded round neck OD and let er rip, my shoulder wasn’t rolled at all in fact it looked pretty darn good so I loaded more of the same.

I’ve done well over 1000 BR cases to Dasher, using the false shoulder method. You get a very snug fit between the bolt face and the case neck. Search this site there’s several ways to do it. I have used the false shoulder with a bullet and shot matches with the rounds. After pulling the trigger you have a Dasher case.

Just check the neck diameter of your loaded rounds against the chamber.

Will Lapua brass work with an Alpha chamber? It was reamed with an alpha reamer. Reason I asked is because some fella said to use Lapua brass with regular reamer, and Alpha brass with Alpha reamer, can you confirm on this?

Can you dumb this down for me please?

I used three thousand neck tension to hold the bullet at .010 jam into the riflings while fire forming my Lapua 6 br cases into Dasher cases.

Understood, thanks

Given you've fired at once as 6BR, it may not blow out as easily as new brass. Maybe anneal first? Just a thought.

With 1X fired Lapua 6BR brass, anneal at the body shoulder junction first, then you may get most to fireform without many shoulder splits.

OP, did you ever get an answer to this question?

If so, what was the consensus?

Our dasher reamer will work with other manufacturers brass no problem. We have run peterson and lapua. The only case that it doesn't work with is the long neck norma brass.
