[QUOTE="jensenj71, post: 2745992, member: 96797"] My 338 Edge will raise a circular bump where the ejector sits with softer brass at higher pressures. I have really only seen it with Nosler brass. Opening the bolt actual shears off part of the edge of the bump creating very fine hair like shavings. No issue with the case extracting from the chamber, but as the bolt first starts to rotate the raised bump gets rubbed. Rechambering a fired brass is tight because the bump is 0.001" to 0.002" tall and doesn't line back up with the extractor. A couple of passes of the case base across sand paper reveals and removes the bump. I just backed off on pressure with the softer brass. I can easily get 2900fps with 300SMK with H1000 and 30" barrel with other brass. My preferred load is 2825fps. [/QUOTE]
