It is a 300 SAUM (NORMA case) or 7saum other? It is shortened to roughly the same body length as a Creedmore but with a .320" neck. We haven't shot them enough to say exactly what barrel life is, but my 6.5 Sherman has 1700 rounds through it and still shoots well. This case holds 4+ grains less powder than the Sherman and has a longer neck so it should do even better than the Sherman. With 2.9" you should be able to load even the 160's clear to the lands.......rich
It is throated for the 140's being seated at the boat tail junction. We have pushed the 160 Matrix to 3184' in a 29" barrel so 3100' is doable in a 26", but that is MAX!
