Lapua Brass

[mjbine]

I have just purchase some Lapua brass for the first time. I am going to used it in my 243AI. What type of prep is needed with Laupa Brass? Do you still have to deburr the flash hole, uniform the primer pockets or not? I know with Winchester it is a must.

Thanks

You tell us
It's your brass

I use Lapua, Norma, and Winchestor in various cartridges. I have seen each better and worse than the others from lot to lot.
You check it and do what ya need or want to do

I normally don't have to de-burr the flash holes. I do trim to uniform length.

Also make sure to reduce your loads to start, depending on the caliber and lot # Lapua brass tends to be thicker and heavier, the loads you used in the Win. cases could produce very high pressure in Lapua cases!!!!
