I’ve been using Peterson 6BR and 280AI brass for a long time with the 6BR now at about 15 loads and primer pockets still tight. I do clean and anneal {AMP} @ time and have never lost a piece of brass yet aside from having to cook off one piece to get the Aztec code for the annealer.I do love me some Lapua brass.
That being said, I've now bought Peterson in 6CM SRP and LRP, .260 Rem, and 300 PRC that I necked down. In all four, I've managed single digit SDs, and in the three standard .478 bolt face cartridges I've got handloads that routinely go sub half-minute for five shot groups.
I will not hesitate to buy more... but really availability has been the biggest driving factor for me. I am not a benchrest guy, so half MOA and single-digit SDs are my happy spot.
No issues with the reloading process either and Peterson. However I will admit that I'm only only my 3rd firing of some of it... so perhaps something ugly will rear its head later. Lapua brass is awesome for longevity.
With the introduction of tariffs on European products price may now also be a factor in your choice… A quality product that won’t disappoint.
